How to Revive Faulty Hard Disk

20 December 2008

Introduction
There are many reasons why computer always hang or run slowly or sometimes, even re-start itself. One of reasons can be traced to the harddisk failure. Normally, one would repair the harddisk by recovering the bad sectors using "Chkdsk" in the "Windows Recovery Console". However, there will be times that even this method won’t help. This article will describe another method to revive that harddisk.

How Long the Harddisk will last After the Revival?
It will depend on the condition of the harddisk. If the harddisk had a crash, there is a good chance that the harddisk will not last too long before it will fail again. Therefore, it is good to make a safe copy of the important data in the harddisk whenever possible.

Harddrives are quite cheap nowaday; it will make good sense to replace rather than to repair or revive them. But if one had decided to give the revival a try, this article will describe one method.

What’s needed?
1. Low Level format software (free to download from here)
2. Partitioning software such as Partition Magic or equivalent

Step by Step Procedures

Using PartitionMagic

a) Non Destructive Method
This method will make use of the PartitionMagic to create a new partition to isolate the bad section and to use the healthy part of the harddisk.

The method will retain most of the applications and programs in the harddisk. One might have to perform a low level format describe in Section (b) when there are too many bad sectors in the harddisk.

1. Estimate where to create this partition
When performing "Chkdsk" operation, observe the progress counter and note down its percentage when Chkdsk got stuck. The following example will assume that the counter got stuck at 75% while checking D: drive.

2. Start up PartitionMagic
One would be greeted by this screen that shows all the partitions in the harddisk.




3. Create New Partition
Select to “create new partition” in the “Wizard” and after answering a few questions about how to use new partition and the type of file system, one would come to the following screen where one would have to specify the location for the new partition.

Since the Chkdsk counter was stuck at 75% when scanning D: drive and D: has 50 GB, one would like to create a new partition between D: drive and E: drive and take about 35-40% off from D: drive to make this new partition. One might have to release some space in D: drive if it is full. New partition can only be created from free and unused disk space.
In case when error is encountered during the process of creating a new partition, either try to resize or erase the new partition, then assign a smaller size of partition to isolate the faulty session,


Click “Finish” and subsequently, click “Apply Change” to make the changes. Thereafter, format the entire disk so that a drive number can be assigned to the new partition just created.
 

4. Check For Errors

Check the various partitions for errors using the utility programs available under the “operation” menu of the PartitionMagic. Resize the new partition and recheck for error if necessary.

(Note: The above example assumed that the harddisk is still working with some errors in one section. If the faulty harddisk cannot start properly, one would have to hook the harddisk as a slave. The latter is always recommended because one might have to tweak the size of the new partition to locate the faulty section and it would save the trouble of re-starting the computer to change the partition sizes)

Other Tools (Updated 1 May 2021)

MiniTool Partition

1.  Download free software from here

2.  Similar to MagicPartition,  this MiniTool software can also perform the same tasks.  The paid versions can also backup & recover data

b) Destructive Method: Low Level Format
When there are too many bad sectors or faulty sections in the harddisk, it is always good to backup the important data and perform a low level formatting. This low level formatting will always require the faulty drive to be hooked up as a slave drive.

1. Download the low level format program from here.

2. After installation, run “LLFTOOL.EXE” and follow the instruction to select the faulty drive and then select low level format page.

Double confirm the correct faulty drive before you press the button “FORMAT THIS DEVICE” because all data in the drive will be erased and gone permanently.

3. Create new partitions and reformat the harddisk as if it is a new harddisk
4. Reinstall operating system and the rest of the applications/software
Note: If one still encounters problem, one can go through the Section (a) again to isolate the faulty sections.

VIX, DOW and Market Movement

18 December 2008

IntroductionThe Volatility Index, commonly known as VIX, is a Futures stock index traded in the Chicago Stock Exchange. It is often referred to as the barometer of investors’ confidence in equity market. It indicates the investor sentiment and market volatility. A higher VIX will indicate a lower DOW and vice versa.

What happened to VIX lately?
The attached chart shows that VIX was having very volatile trades lately; it climbed from $20 on 1 Sept 2008 to $80 on 27 October 2008, a hefty $ 60/= or 300% jump, which had never been seen before since 1993 when VIX was first introduced. Then it made a double top formation and plunged 40% to the present level of about $50 through volatile trades.

(Doubleclick for larger view)

What's the use of VIX?
VIX has volatile trades; hence, it is good gauge to judge the movement of the equity markets, which usually have less volatile trades that make future prediction difficult.

Where Can I Get Free Quotes?One can get free quote of VIX from here and DOW from here.
Where is VIX Heading?
The attached chart shows many weaknesses of VIX; for example:

a) It has just formed a double top formation and is presently declining from its second peak;
b) It's 20 MA (green) is about to cross under the 50 MA(blue), meaning VIX is about to start its decline;
c) The top and bottom Bollinger bands are falling together with falling 20 MA and flattening 50 MA;
d) The stochastic is showing a “falling peak” with VIX dropping steadily into the oversold region. There are still rooms for further declines.

The above weaknesses will show that VIX is presently under heavy selling pressure. One should soon see VIX started to yield once it crosses below the double top support (red) at around $48.

According to rule of thumb, once VIX crosses under the double top support, it will target for $15, which a projection from the base double top support, using equal length measured from the tip of the double top to the base support.

Where would DOW be then?
There is no direct co-relationship between DOW's and VIX’s movement. But if there is any indication at all, DOW will move up when VIX is moving down. However, if the projection of VIX is correct with a target of $15, DOW may be targeting around or max out at 13,000. But to reach that level, DOW would have to break several resistances including the one at 200 MA, which could be a "tough nut to crack" unless DOW is supported by very good news and economy figures.

The US National Debts

10 December 2008

Introduction
The US Congress has just approved the bills to bailout the Wall street's Banking sector, then AIG, the insurance sector and now the 3 big autos in the automobile industry. These bailouts were estimated to be more than US$ 1 Trillion. One might ask, where does the US Government get all these money from?

The US National Debt
The U.S. National Debt is now well over $10 trillion. This is nearly double the debt in 2000, which was $6 trillion, and $1.3 trillion more than 2 year ago, when the debt was $8.7 trillion.

What's happened in the US? How can the US accumulated such debts? Who have caused all these debts?

The I.O.U.S.A Documentary Film
A documentary film called the I.O.U.S.A, tried to explain all about these US National debts in its 30-minute video shown attached.

A Nuclear Power Plant Proposal for Singapore

5 December 2008

Introduction
Singapore is too small to have a Nuclear Power Plant. “We must have the power plant located at least 30 km away from populated area”, said our Minister Mentor, Mr. Lee Kuan Yew, in a recent presentation on 5 November 2008. This article will introduce a nuclear power plant option that we can use safely in Singapore.

What is this Option?
The mini or miniature nuclear power plant (MNPP) that can be installed underground and underneath each and every HDB block. These MNPPs will not have the Chernobyl effect nor will they require the 30 km clearance rule.

What are these MNPPs ?
The MNPPs are small and self contained nuclear power generating plants that have mini or miniature or even micro reactors. The smallest reactor is about the size of a bath room (about 12 m2) and the largest, about the size of a badminton court (about 50 m2).



They can supply electricity from 200 kw, enough for a HDB block to about 45 MW, enough for 45,000 homes in Ang Mo Kio New Town. Together with other ancillary equipment such as steam turbines and generators, a 50 MW MNPP may need a space as big as a JTC factory or about 1,500 m2.

The advantage of MNPP is that the whole plant can be buried underground as shown attached.




The complete reactor unit can be manufactured in a factory, then shipped to site and then returned back to the factory for refueling.

The testing model is said to contain no cooling tower with minimum maintenance requirement. The residual or excess steam can be vented into the outer shell, where it will condense into water that can be collected and recirculated to cool the core. It would use no primary water pumps.

How Long will the Fuel last before next refueling?
Each reactor has a fuel supply for 7 to 10 years. The refueling can be done in the factory. The 200 kw Toshiba unit claimed to have a fuel supply of 40 years for a single block of building.

How Safe are these MNPPs?
According to manufacturer’s claim, the reactor is designed based on a 50-year-old design that has been proven to be safe for the students to use. They expect little objection from the countries to use the MNPPs.

What are the Expected Installation requirement ?
The MNPP can be installed underground and underneath any building.

Depth
The depth at where the reactor to be located will depend on the explosion power of the nuclear reactor. Toshiba recommended the reactor be buried 30 meters under ground in a sealed container so that it would not be easily reached by earth moving equipment.

Encasement
The reactor is expected to be surrounded by strong layers of steel, lead, and concrete in order to protect their operators from excessive radiation levels.

What about cost ?
The Chief Executive of Hyperion, who has about 100 orders, said "Our goal is to generate electricity for US 10 cents a kilowatt-hr anywhere in the world". MNPP will cost approximately US$25m each. For a community with 10,000 households, that is a very affordable US$2,500 per home.

When can we expect to use MNPP?
The MNPP is presently being developed and tested in US and in UK and would become commercially available in year 2015. In UK, Hyperion (Now changed to Gen4Energy) planned to set up three factories to produce 4,000 MNPP between 2013 and 2023. They have a pipeline for 100 MNPPs with a 6-year waiting list.

MNPP Accidents
MNPP was first used in the US in early 50s. Then most MNPP were above ground. In 1961, there was an accident happened in a facility, located at the National Reactor Testing Station approximately forty miles (60 km) west of Idaho Falls, Idaho. 2 people were killed and about 22 people were exposed to some radiations. The MNPP were subsequently buried to contain the damage.

Update: March 2016

1.  Development of Samll Modular Reactors

United Kingdom

In 2016 it was reported that the UK Government was assessing sites for deploying SMRs in Wales - including the former Trawsfynydd nuclear power station - and on the site of former nuclear or coal-fired power stations in Northern England. Existing nuclear sites including Bradwell, Hartlepool, Heysham, Oldbury, Sizewell, Sellafield and Wylfa are thought to be possibilities.^[9]

United States

The Tennessee Valley Authority announced it will be submitting an Early Site Permit Application (ESPA) to the Nuclear Regulatory Commission in May 2016 for potentially siting an SMR at its Clinch River Site in Tennessee. This ESPA would be valid for up to 20 years, and addresses site safety, environmental protection and emergency preparedness associated. TVA has not made a technology selection so this ESPA would be applicable for any of the light-water reactor SMR designs under development in the United States. ^[10]
The Utah Associated Municipal Power Systems (UAMPS) announced a teaming partnership with Energy Northwest to explore siting a NuScale Power reactor in Idaho, possibly on the Department of Energy's Idaho National Laboratory.^[11]
The Galena Nuclear Power Plant in Galena, Alaska was a proposed micro nuclear reactor installation intended to reduce the costs and environmental pollution required to power the town. It was a potential deployment for the Toshiba 4S reactor.

How Much Can One Profit From a Recession?

Introduction

There are fears that market will plunge during a bear market in a recession. But a study has shown that market could rebounce and rise 25% from its low before the recession is officially declared to be over.

The Table

The attached table from a study shows 14 recessions where bear market lasted for 6 to 34 months, the longest being the “Great Depression” in 1929. The table shows the following:

a) An average return of 8.7%, if one were to stay invested throughout the recession periods;

b) A profit as high as 25% if one were to invest during the lows and take profit by the time the recession is declared over.

The table also shows that not all the recessions have noticeable bear markets and also, 8 out of 11 recessions have created another new bull market when the recession is over.

Today and Yesterday's Bear Market

New York Times has an interesting chart that compares the present bear market of 2008 with the rest of the bear markets of yesterday.
The present bear market appears to track the 1942 or the 1973/74 bear market except the momentum is quite similar to the 1942 than 1973/74 bear market. It is hopeful that we are tracking the 73/74 market or 1st part of 1932 as we have the second World War in the 1942 market.

Why STI is Down Today?

1 December 2008

Introduction
Why STI is down when DOW and the US markets were up last Friday? This article will try to explain using very simple technical tools called simple moving average curves.


Why is Simple Moving Average ?
A Simple moving average is just an average value of a stock price, or indicator, averaging over a period of time. The term "moving" implies the average value will change or move. As the stock's price changes over time, its average price moves up or down.


Where Can I Watch Simple Moving Average Curve?
One can watch it from the any technical analysis software or free from Yahoo website. The latter only give Daily chart. Some private website, such as Shareinvestor.com , can provide intraday charts, such as 60-minute chart for a fee.

How Can I use Simple Moving Average Curves?
Most common curves being used are 200-day(200), 50-day(50) and 20-day (20) moving average(MA). The 5-day MA and 10-day MA are often used by Day Traders for day to day tradings. Among the curves, the 20 MA is most commonly used. It acts like a magnet that stock prices or indexes will always fall back after wondering away.

The MA curves are actually the supports as well as resistances of a stock price or index. For example, the 60-minute chart attached shows that STI has crossed over the 20 MA (green) and 50 MA(blue) and these lines becomes the support lines. STI is now testing the 200 MA (red) line, which is now the resistance line.

Apparently, STI just failed in the morning to break the 200 MA resistance line and index started to fall. It will fall towards the 50MA or 20 MA and wait. However from the chart, one can see that this is the 3rd time STI is testing the 200 MA line. It is always said that as more times a resistance or support is tested, it will break eventually. The rising 20 MA and 50 MA are at present supporting this action to break the 200 MA line.

What Would Happened if STI Breaks the 200 MA?
200 MA is usually taken as an important support or resistance line as it always indicate the health of the index or stock price going ahead. If the 200 MA is broken, it would then become the support that will bring STI to new highs; otherwise, it would just remain as a resistance.

Can We See What Happened in the Daily Chart?
The 200 MA may reflect in the Daily Chart as an important support or resistance event. In this case as shown in the daily chart attached, STI is about to cross the 20-day MA (green). If the resistance of the 200 MA in the 60-minute chart is broken, it would mean that STI would be able to break the 20-day MA resistance in time to come.

The side-way movement of the 20-day MA in the Daily Chart indicates that STI has begun its recovery process. If the 20-day MA resistance is broken, STI would want to head for the next resistance, which will be the 50-day moving average. On the other hand, it might reverse to go down to meet the lower trendline of the triangle that had been enclosing it since Oct. STI will want to seek lower lows, lower than 1,600 if the lower trendline is broken.

Soft Water Supply for Humidifiers

Introduction
Using hard water directly from running taps often kills the electronic ultrasonic humidifier. This is because hard water will form scales that will eventually damage the ultrasonic vibrator of the humidifier. This article will describe a method where one can obtain reasonably clean soft water for proper humidifier operation.

What is Hard and Soft Water ?
Water is said to be "hard" when it contains minerals such as calcium carbonates and other derivatives or metal oxides. Hard water usually comes from the ground water that contains a lot of minerals. One can turn hard water into soft water simply by boiling. The other way is to use reverse osmosis machines. But these methods will use a lot of energy. The other method is to find soft water sources. One of the many sources is rain water but it is not clean. Yet another method is to use condensate water.

How Do We Get Condensate Water?
One can get condensate water from cooling the air. When air is cooled to its dew point temperature (around 25 degree C depending on where you live), moisture in the air will condensate into water. One can get this water from a special water making machine.

or simply from any air-conditioning unit. This article will concentrate on how to obtain clean soft water from our normal air conditioning units.

Condensate Water from Air-Conditioner Units

Every air-conditioner unit will have a condensate water piping running from the cooling or evaporating coils to the nearest drain. This water is usually clean except for some dust particulates that are also collected together with the air that passes through the evaporator coil. Dirty water tray and piping can also pollute this water. To get clean condensate water, one must prepare the air-conditioner unit and install a water filter to receive and store the water. To filter and store the water, one can use the common mineral water filter shown as follows:-



Preparing the Air-Conditioner Unit

Every air-conditioner unit has a plastic water tray underneath each evaporator coil. This tray is always connected to a drain pipe. One must always ensure that this tray and the drain pipe are always clean and free from algae forming. One must also change the air filter at least once every month, depending on the usage.  Additional secondary air filter can be added to the evaporator coil for cleaner water to be produced.

Preparing the Mineral Water Filter

Mineral Water Filter (MWF) has a dome shape ceramic filter on top and a plastic cylinder that is filled with various mineral sand and stones.


To ensure the water remain soft, one must remove the cylinder of mineral sand or stones or replace them with silica sand that has no mineral content.

Making Water Overflow and Drain Pipe

One would have to make additional holes in the MWF for inserting overflow pipes in the top plastic container as well as the storage container as shown. The existing drain pipe should be cut and be diverted to fill water into the MWF. The new overflow pipes should be connected to the existing drain pipe as shown with a T-joint.

To facilitate the plumbing work, one could use 6 mm diameter PVC pipes as they can be easily cut and bent to shape for proper installation.

What about Water Borne Diseases?Legionnaire bacterias and algae pores are often found in water of cooling towers of the air-conditioning system; however, legionnaire bacteria will not thrive in air conditioning condensate water because the water temperature are usually below 16 degree C. One may found certain type of algae pores in the condensate water system if the system has not cleaned regularly. Nonetheless, legionnaire bacterias and algae pores are usually more than 3 microns in size. They will be filtered out by the ceramic filter of the WMF which has pores smaller than 0.5 microns. Should some algae or bacterias pass through the ceramic filters, it would not have survived because:

1. There isn't much nutrient in the filtered water to feed the bacterias/pore;
2. The ultrasonic vibrator of the humidifiers would have killed these bacteria/pore as it has some sterilising effects.


Other Usage of Soft Water
Soft water can be used in many areas where scaling is always a problem

a) in steam irons

b) in steamers


c) In Automobile as battery distilled and radiator water.

How to Make XP Run Fast again

IntroductionOften heard people complaining that their computers have been running very slow lately; sometimes, the computers may re-start itself for no reason. Running the virus scanning software did not detect any viruse. Some people resort to reformatting the harddisk which will clean the harddisk but will require one to re-install all the programs and application.
This article will describe some steps to solve some of these problems and keep the computer in tip top condition again.

Why Run Slow?Top of the list has to do with computer viruses. The other has to do with computer parasites. Besides these problems, the computer may not be as healthy. For example, the harddisk may have a lot of bad sectors or the CPU performance may be affected by faulty CPU fans etc.

Step by Step Solution1) Repairing the HarddiskIt is always good to start the troubleshooting process by checking and repairing the harddisk. Many problems are associated with bad sectors or media in harddisk. When computer encounters some read/write problem in the harddisk, it will slow down the computer; sometimes, the computer may just re-start itself without any reason. The bad media would also corrupt the master boot sectors or boot files and prevent the computer from normal startups. Once these problems are cleared, the computer should work faster and better to perform the other steps.

To check and repair the harddisk, please refer to this article.

2) Restart the computer
3) Clear the computer virusesRun whatever virus or spyware scanning software available, making sure one's computer is free from these nasty viruses.

4) Clean the rubbish and get rid of parasitesAs we use the computer, we build up rubbish and cultivate computer parasites. They are stored inside the harddisk. Computer Parasites, such as internet temporary files, are not only occupying harddisk space but also reducing the computer operating speed. These parasites are often loaded onto the computer memories without one's permission and they often takes up computer bandwidth. To clean the rubbish and get rid of the parasites, please follow the following step by step procedure

Cleaning the HardDisk
Step a: Backup the Registry and System State
It is advisable to backup the registry and the system state before carrying any modification to the registry. Follow this article to back up the registry and the system state.

Step b:Download CCleaner from this website, install and then run it (note: this cleaner is safe to use; no viruses or spyware ever detected). After starting up, one will get to the following frame:-


Uncheck the necessary checkboxes; for example, if one prefers to keep the “cookies” that store the various passwords or userids of the frequently visited website, just uncheck the “Cookie” checkbox. One would be surprised how much files that CCleaner will be able to get rid of and disk space freed up.

Alternatively, one could also use the file and cookie cleaning functions of the Internet browser; for example, in the Internet Explorer, one could use Tools/option in the menu and then select to delete the cookies or the Internet files. The other way is to use the “Clean Manager” function of the Window.

Step c: Clean the Registry
To get rid of the unwanted registry entries and entry parasites. This cleanup will make your computer run faster and smoother.
a) First, create a restore point of the registry (important). To do so, go to the restore page by clicking "start" then "All programs/accessories/system tools/System Restore" and then follow the instruction to create a restore point. Alternatively, on can click "start" button and then "run". In the drop down box, enter "%systemroot%\system32\restore\rstrui.exe" (without quotes) and click ok. The system restore point would enable one to restore the computer to its original condition when the registry is written over or damaged.
b) In the sidebar of the CCleaner, click "Registry". In the new window, click "Scan for issues". When prompted for saving, click yes. One may have to do at least 3 registry scanning before one can completely clean the registry.
Step d: Re-start the computer

5) Done. Your computer should run as fast as new.

Installation Failures in Windows Live Messenger

5 November 2008

Introduction
MSN Live Messenger is a free to use product that enables one to use internet to talk live over a webcam. Once installed, it is relative free and easy to use. However, the installation program is quite sensitive and a re-installation may not always be successful. One can try all tricks; cleaning up memory caches, internet temporary files, clean up Registry, clean all the files and all methods precribed, it just failed. This article will describe a method that has been successfully used under such conditions.

What happened?
There are many versions of what went wrong. One would get error code messages such as 0x80070643 or 0x80070057 or 0x8000ffff with scaring warnings such as "catastrophic failures", "major system failures" and other messages like "Windows Live Suite was not installed". After one has fixed all these errors, then come the sickening part; waiting for half an hour to get another “X Not installed” message, this time without any good help.

According to some forum discussions, the cause could be due to some parts or information of an older version still left in the harddisk or in the registry. Some said it had something to do with the "Windows Validity Checks" problems. The Live Message installer just could not get rid of these problems for some reason.

What to do next?
Carry out all the recommendation/advice given by Live Messager Installer
a) Making sure that one has the required capacity in the hard disk
b) Clean the internet files by using Internet Explorer's Tools/Internet option, then click "delete files"
c) Clean the harddisk by clicking start/run, then in the dropdown box, enter "cleanmgr"(without quotes) and select the default drive (C:) and clean all necessary files
d) Go to Control panel and click icon "Add/Remove program" and remove all the files associated with "Windows live" or "Live Messenger" programs
e) Download this Windows Installer CleanUp Utility program and run it. If the program does not self start, run it by clicking Start-> All Programs-> Windows Install Clean Up.

After starting up the Windows Installer CleanUp, delete all the programs that are associated with Windows Live Messenger, be it mail, tool bars, photo gallery or any other program. Search through the program names; sometimes, "Windows live" are used and hidden behind some program names. Go through the program lines one by one.
f) Download and run this full version Windows Live Messenger 8.1 from the MS website or this site (18 MB). This full version program will bypass most of the checks required normally.
Note:
1. If one were to fail to install the Windows Live Messenger using the full version installer, try to reboot the computer after having cleared the check boxes temporary in the startup tab of the MSconfig program. Thereafter, install the full version Live Messenger installer again after the starting up. There is a possibility that some 3rd party drivers or the old messenger programs could have started up during booting and could have affected the installation process. To uncheck the boxes in MSconfig:

• Click Start/run and in the dropdown box, enter "msconfig"(without quote) and click ok. In the Startup tab, note down and remember which check boxes have been ticked and untick those check boxes.
• Remember to replace the ticks of the check box after the successful installation of the Live Messenger

2) If the installation fails again, search through the program files folder (c:\program files) and delete

• Messenger folder
• Windows Live Messenger folder
• Any other folders e.g Live Messenger Toolbox
• if necessary, use Regseeker to clean up registry that has named after "Windows live" & "MSN Messenger" or "Messenger". A free copy of the Regseeker can be downloaded here.
Re-install the program again after a fresh startup.

3) One can try to install the following Microsoft Windows Live Messenger Full Version also:

a) Microsoft Window Live Messenger 8.0 from here
b) Microsoft Window Live Messenger 2008 (8.5.1) from here.
c) Microsoft Windows Live Messenger 2009 (9.0) from here.
