Your hard drive is failing. Back up your data immediately and replace the hard drive. Clean-install Windows.

If the computer will not boot, there are a few things you can do
to try and get data off the drive. Success depends on how badly the drive is damaged. When this is all over, create and implement a backup strategy so you don't lose data again.

General data recovery methods:

*IMPORTANT* - If there is any question that the drive is at fault - it's making noises for instance - and the data is crucial DO NOTHING FURTHER ON THE DRIVE. Every time you spin that drive up you may be destroying data. If this is the case, send the drive to a professional data recovery company like Drive Savers (my preference) or Seagate Data Recovery. General prices run from $500USD on up. Drive Savers recovered all the data on a failed laptop drive for one of my clients and it cost$2,700. He thought it was worth the money; only you know what your data
is worth. I understand that some insurance companies are now covering data recovery charges so check with yours.

If you don't want to send the drive to a professional data recovery
company, you can try:

1. Pull the drive and slave it in a computer running a working install of XP. Depending on the target drive's characteristics, you may need a drive adapter; i.e., laptop-to-IDE or a SATA controller card, etc. A usb/firewire external drive enclosure works very well, too. Use the working Windows Explorer to copy the data to the rescue system's hard drive and then burn the data to cd or dvd.

2. Often XP will not boot with a slaved drive that has a damaged file system. In that case, boot the target computer with either a Bart's PE or a Linux live cd such as Knoppix and retrieve the data that way. Here is general information on using Knoppix for this:

You will need a computer with two cd drives, one of which is a cd/dvd-rw OR a usb thumb drive with enough capacity to hold your data OR an external usb/firewire hard drive formatted FAT32 (not NTFS). To get Knoppix, you need a computer with a fast Internet connection and third-party burning software. Download the Knoppix .iso and create your bootable cd. Then boot with it and it will be able to see the Windows files. If you are using the usb thumb drive or the external hard drive, right-click on its icon (on the Desktop) to get its properties and uncheck the box that says "Read Only". Then click on it to open it. Note that the default mouse action in the window manager used by Knoppix
(KDE) is a single click to open instead of the traditional MS Windows' double-click. Otherwise, use the K3b burning program to burn the files to cd/dvd-r's. - Bart's PE Builder

If you can't get data off by attaching the drive to a working XP system or by booting with Knoppix, then data recovery software will in all probability not work because the hard drive is too physically damaged.

To solve this problem you can you do the following:
Start the PC and keep pressing the F10 key so that you can enter into the BIOS Setup. There you run the self test hard disk, be patient, it will take time. After it finishes, press F10, select the option Save settings and exit. Then while booting the system press F8 and select Last known good configuration. If still the problem persists, Restore your PC with the Restore Disc.

If this error is coming from the PC Doctor or When the OS (WindowsXP, if it is) then the chances are that your hard drive is failing. Back up your data immediately and replace the hard drive. Remove the HDD and connect it as a slave into another system and copy the data. Cheers - Parveen

When computer boots up I get this error code A disk read error occured code 0F00:0666

A bad hard drive or the boot sector (the map of the hard drive contents) has an error.

You have two choices. If you run regular backups you can do a full restore including the boot sector, if not, you'd have to format the hard drive and lose your data. Then reinstall Windows and start from scratch.

The other option that loses your data, as well, is replacing the hard drive if it's defective.

Computer won't boot up. Error code 0146 and error code 2000-0146

Good day.
Error code 0146 basically refers to a hard drive. This means your computer is not detecting properly your hard drive or your hard drive itself is defective.
Let's first isolate the problem. Go to your BIOS setup (Pressing F2 upon power on) and check if your hard drive is properly setup in your BIOS. Make some necessary adjustments and save setting.
Turn-off your pc and try to check the data cable and the power cable is properly connected to your hard drive. You may also try re-seating the data and power cables - remove first and then connecting it again to the hard drive. Loose cables may cause problems. Power on the pc.
If you still receive the same error, then you need to replace the hard drive with another one.
Good luck.

Hard drive on an eMachine computer desktop has crashed. Computer won't boot. Is there anyway to get files off the crashed hard drive?

take the hard drive to a local computer guru... recovery will depend on what caused the crash, and what has happened since then. Basically, he or she will need to try to boot your hard drive with another tower, or pull all the info directly from the disks themselves. If you had to ask this question, you're gonna need help to fix it.... Sorry.

If you are getting format errors on the hard drive, the most likely failure point is the HDD itself. If you have tried a known good hard drive, then next item I'd suspect would be the system RAM

Error code 0146 , can you help me ?

If this is a Dell computer , it indicates a hard drive failure. if so here is the solution:
Look at the bios and see if the hard drive is detected.
To get to the BIOS, when you turn on the system, you will be confronted with a black screen with the dell symbol in the middle, if you look at the top left of the screen, you should see something like
Press F2 for boot options
Press F12 for setup
Keep tapping the F2 or F12 key for boot options. this will take you into the BIOS.
Check also that it says enabled
Next see if you can boot the dell diagnostics partition. {F12}, then select diagnostics, once you have the diagnostics available run the memory tests and the hard drive test.
you should get a report when it finishes looking something like this:
DST Short Test: Failed
Error Code: 1000-0146
Msg: Unit 2 : DST LOC Contains previous error(s)

0F00: 0244
MSG Block: 57301297

MSG Block: 57301297
if there are more than two errors ide suggest a new hard drive. BUT TO SAVE YOUR DATA BEFORE ------>Do you have anything important? if you do, you will need to do a repair install of XP and get your files before the hard drive fails completely. Use the service tag to obtain full specs of the computer at dells website. This hard drive has previous errors, and has generated new ones. It looks like it is getting ready to fail. You may be able to use a xp disk to perform an operating system repair, the dell operating system CD will do this also. Here is a link: If you follow the directions exactly, you will not lose any files. Please continue to post about this issue, and operate this computer as little as possible.

Hi, I get an error message when I try to connect and install a Maxtor 500 GB external hard drive to my computer. The message reads "the device cannot start (Code 10). Can you assist?

What is the error message you get?

What OS are you using?

Depends on your hard drive, some computer commonly ask for a driver when you plug something in it. might as well try reading the manual of your external hard drive, if it doesn't require a driver, then the problem "might" be in your operating system and/or in your computer.

Computer giving error: "harddrive error press ctrt alt sup to restart" on start up please help.

Generally, such an error indicates the hard drive has had a severe failure and needs to be replaced.

If a portable, you can try reseating the drive. If a desktop, you can reseat the cables.

Check in the system BIOS, see if the hard drive is identified by size/model, if it is, then you can try running diagnostics on the drive to see if you can get a failure code.

if diagnostics pass, you can try booting to your Windows CD, and run tools like CHKDSK and BOOTCFG /rebuild to fix the file system.

But you are getting a BIOS level error from what you describe and that usually means replacing the hard drive.

If you are unable to access your welcome screen, and it is giving you a hard drive related error, it may be possible either your operating system is corrupt or your hard drive has failed. If you have already tried your recovery disc, your hard drive itself may be at fault.

First, verify that there are no discs in any drives, such as floppy or CD and then try to turn your computer on. If you cannot get to your welcome screen and you get an error about your hard drive, try using your recovery discs. If that doesn't work, you most likely have a faulty piece of hardware in your system, most likely your hard drive.
