Hard drive gone bad?

The most common problems originate
from corruption of the master boot record, FAT, or directory.
Those are soft problems which can usually be taken care of
with a combination of tools like Fdisk /mbr to refresh the
master boot record followed by a reboot and Norton disk doctor
or Spinneret.

The most common hardware problems are a bad controller, a bad
drive motor, or a bad head mechanism.

1. Can the BIOS see and identify the hard drive correctly? If
it can’t, then the hard drives onboard controller is bad.

2. Does the drive spin and maintain a constant velocity? If it
does, that’s good news. The motor is functioning.

3. If the drive surges and dies, the most likely cause is a
bad controller (assuming the drive is cool). A gate allowing
the current to drive the motor may not be staying open. The
drive needs a new controller.

4. Do you hear a lot of head clatter when the machine is
turned on and initialized (but before the system attempts to
access the hard drive). Head clatter would indicate that the
spindle bearings are sloppy or worn badly. Maybe even lose and
flopping around inside.

5. There is always the possibility that the controller you are
using in the machine has gone south.

1. If the drive spins, try booting to the A> prompt, run Fdisk
and check to see if Fdisk can see a partition on the hard
drive. If Fdisk can see the partition, that means that it can
access the drive and that the controller electronics are
functioning correctly. If there is no head clatter, it may be
just a matter of disk corruption which commonly occurs when a
surge hits you machine and overwhelms the power supply voltage
regulator. It commonly over whelms the system electronics
allowing an EM pulse to wipe out the master boot record, file
allocations table, and primary directory. Fdisk can fix the
master boot record and Norton Disk Doctor can restore the FAT
and Directory from the secondaries.
2. The drive spins but Fdisk can’t see it. Try the drive in
another system and repeat the test to confirm that Fdisk can’t
read through the drives onboard controller. If it sees it in
another system, then your machines hard drive interface is
bad. You can try an upgraded or replacement controller card
like a Promise or CMD Technologies (there are others) in you
machine after disabling the integrated controller in the BIOS,
but if the integrated controller went south, it may just be
symptomatic of further failures and you’d be wise to replace
the motherboard. Trying the drive in another machine also
eliminates the variable that your machines 12 volt power
output being bad

3. If you get head clatter but a constant velocity on the
drive motor (no surging), you might try sticking the hard
drive in the freezer for about 12 hours. This is an old trick
from back in the days of the MFM/ESDI driver era. This can
cause the drive components to shrink enough to make the track
marker align with the tracks. We don’t see that kind of
platter spindle wear much anymore, but back in the old days,
the balancing and bearings weren’t as good. Still, under the
right circumstances, it might help. It would depend on how old
the drive is and how many hours of wear have occurred. You
have to be quick to get your info off the drive when it works.
Back then, the drives were much smaller, so there wasn’t so
much to copy. So, go after the important data first.

4. The drive doesn’t spin. Either the onboard controller is
bad or the motor is bad (assuming you did try the drive in
another machine). It’s time to hit the net and local
independent shops to see if you can locate another drive of
the same make and model that’s good. Since the drive is
probably an older drive and no longer in distribution, your
best bet is to find an identical used drive. If you know
someone with the same make and model, you might be wise to try
and persuade them to sell you their drive with an offer of
providing them with a free upgraded drive. If you can locate
an identical drive, start with the controller replacement …
this is the simplest and least invasive. If swapping the
controller doesn’t produce the desire result, you can tear
into the drive and swap the motors. While you have both drive
opened up to accomplish this, scrutinize the platters, heads
and armatures. You might even hook the drive up and power it
from a system with both drives attached. This way, you could
see anything that deviates between the actions of both drives
when they are initialized. Swapping patters is unlikely to
produce any positive result. They are a balanced system like
the tires on your car and I suspect that the balance will be
different for each drive as will other variables.

5. There’s always Ontrack Corp. who will attempt to recoup
your info starting at $500 and going up from there. They don’t
fix and return the drive either.

If the info is all that important to you, I would seek some
professional and experience technician in your locality who
makes his living from servicing and building computer systems
… not just selling them. If you have had much experience
salvaging information from bad hard drives, your likelihood of
success is low. In the case of soft corruption, all utilities
have their eccentricities. Often times, Norton Disk Doctor
will go too far (if you let it). It’s wise to just let those
utilities small steps and then have a look at the drive and
see if you can copy it off. Norton will go so far as to rename
directories and files, and even delete them or break them up
into fragments which are useless.

Here is a trick I found out from which you can protect your files and folders. You may be thinking that you need to download some softwares from internet to do that. Or you may be thinking that I will teach you to protect the files by hiding. NO ! NO ! NO !

You will learn here to make your own software to create FileProtector software. You will be able to do this just by the Notepad and the program provided here. Here is how to do that.

1) Copy the program below starting from #START# and copy upto #STOP#
2) Remove “pankaj” from the program and enter your password there.
3) Open Notepad and paste the program into it.
4) Save the notepad as FileProtector.bat
5) Double Click the FileProtector.bat file. You will see a new folder FileProtector created. There, you can store your files and folders to be password protected.
6) Double Click the file again, type y and press enter. The FileProtector folder will be hidden.
7) Double Click again and enter the password which you had set in STEP 2.
Thats all ! Your FileProtector software has been created. Now enjoy using free software created by you.

Q. What if somebody deletes my batch file ?
A. Don’t worry. You need to only create the batch file again with the same process as you did now and you will get all your files and folders back safely.

#START#
cls
@ECHO OFF
title Folder FileProtector
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST FileProtector goto MDFileProtector
:CONFIRM
echo Unprotected : Press y to lock the folder.
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM

ren FileProtector "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
echo Folder FileProtector
goto End
:UNLOCK
echo Please , give your password to open the protected files !

echo FileProtector Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDFileProtector
md FileProtector
echo FileProtector created successfully
goto End
#STOP#

1. Let your PC boot up completely before opening any applications.

2. Refresh the desktop after closing any application. This will remove any unused files from the RAM.

3. Do not set very large file size images as your wallpaper. Do not keep a wallpaper at all if your PC is low on RAM (less than 64 MB).

4. Do not clutter your Desktop with a lot of shortcuts. Each shortcut on the desktop uses up to 500 bytes of RAM

5. Empty the recycle bin regularly. The files are not really deleted from your hard drive until you empty the recycle bin.

6. Delete the temporary internet files regularly.

7. Defragment your hard drive once every two months. This will free up a lot of space on your hard drive and rearrange the files so that your applications run faster.

8. Always make two partitions in your hard drive. Install all large Softwares (like PSP, Photoshop, 3DS Max etc) in the second partition. Windows uses all the available empty space in C drive as virtual memory when your Computer RAM is full. Keep the C Drive as empty as possible.

9. When installing new Softwares disable the option of having a tray icon. The tray icons use up available RAM, and also slow down the booting of your PC. Also disable the option of starting the application automatically when the PC boots. You can disable these options later on also from the Tools or preferences menu in your application.

10. Protect your PC from dust. Dust causes the CPU cooling fan to jam and slow down thereby gradually heating your CPU and affecting the processing speed. Use compressed air to blow out any dust from the CPU. Never use vacuum.

RAM IS THE WORKING AREA (DESKTOP) OF THE CPU, KEEP IT AS EMPTY AND UNCLUTTERED AS POSSIBLE!

1) Start any application, say Word. Open some large documents.

2) Press CTRL+SHIFT+ESC to open Windows Task Manager and click Processes tab and sort the list in descending order on Mem Usage. You will notice that WINWORD.EXE will be somewhere at the top, using multiple MBs of memory.

3) Now switch to Word and simply minimize it. (Don’t use the Minimize All Windows option of the task bar).

4) Now go back to the Windows Task Manager and see where WINWORD.EXE is listed. Most probably you will not find it at the top. You will typically have to scroll to the bottom of the list to find Word. Now check out the amount of RAM it is using. Surprised? The memory utilization has reduced by a huge amount.

5) Minimize each application that you are currently not working on by clicking on the Minimize button & you can increase the amount of available RAM by a substantial margin. Depending upon the number and type of applications you use together, the difference can be as much as 50 percent of extra RAM.

In any multitasking system, minimizing an application means that it won’t be utilized by the user right now. Therefore, the OS automatically makes the application use virtual memory & keeps bare minimum amounts of the code in physical RAM.

Yes, this is right. You can have live conversation with you offline friends. The real thing is that sometimes the friends who appear offline is not really offline. He may be in invisible mode because he may be busy. You are going to learn how to find who is offline and who is online but in invisible mode.

Firstly open your yahoo messenger main window and double click on the name of the person whom you want to check. The chat window will open obviously.

Click IMVironment button, select See all IMVironments, select Yahoo! Tools or Interactive Fun, and click on Doodle.

After loading the Doodle imvironment there can be these two possibilities :

1. If the user is offline Doodle are will show this “waiting for your friend to load Doodle” continuously . You will see IMAGE 1.

2. If the user is in invisible mode and is online than you will notice IMAGE 2 just few seconds after you see IMAGE 1.

IMAGE 1                            IMAGE 2

Do you want to load the firefox faster so that you can surf faster ? If your answer is yes, than continue reading.

1. Speed your net by 20%

Microsoft reserves 20% of your available bandwidth for their own purposes like Windows Updates and interrogating your PC etc. You can get it back easily. Here is how you can get it back :-

Click Start then Run and type “gpedit.msc” without quotes. This opens the group policy editor. Then go to:

Local Computer Policy/Computer Configuration/Administrative Templates/Network/QOS Packet Scheduler/Limit Reservable Bandwidth

Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the ‘Explain’ tab i.e.”By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default.”
So the trick is to ENABLE reservable bandwidth, then set it to ZERO. This will allow the system to reserve nothing, rather than the default 20%.It works on Win 2000 as well.

2. Speed you dial up net connection

As more and more people get quick connections to the internet, such as cable or ADSL, it becomes apparent to the user of a simple dial-up modem that the World Wide Web can quickly turn into the World Wide Wait. Here a trick that can help speed up your current modem without shelling out the big bucks.

There is a setting located in your windows registry called the Maximum Transfer Unit (MTU). This determines the size of the packets of data sent between your and your server. In Windows 95, this setting is has a value of 1,500 bytes when the actual size of internet packets is 1,000 bytes. This can sometimes slow things down. To remedy the situation, simply follow these steps:

In the registry editor (Start > Run > regedit.exe), navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans. In the NetTrans folder you should find another folder named “000x” in which x represents a fourth digit. Right-click on the “000x” folder and select New and StringValue. Rename the item that appears in the panel on the right side to MaxMTU, then double-click it to bring up the Edit String box and give it a velue of 1002.

Remember to keep playing with the MaxMTU value until you feel that your internet connection has greatly speed up. Some people report huge speed gains using this tricks, while others hardly notice a difference. In any case, it’s definetly worth a try.
