Use your meticulously kept backups, of course.
Normally the disk itself manages its way out of bad sectors, but you can get a notion of how bad it is with utilities and documentation available from WD's site.

If you want to risk the data becoming unrecoverable on a well-degraded disk, you can try using Norton Ghost or something like it (dd in unix) to make an error-tolerant direct copy onto a new volume, and try recovering that with whatever forensic tools and wisdom you like.  There are some livecd distros and designed to make this easy.

Either become really well-read on your model of WD drive by studying the industry and experimenting with many spare similar drives, or send it to the recovery companies with precise notions of what you want recovered and to what media (another HD, or DVDs typically.)

By then, you'll have thought of a backup scheme for the future, too.

Hitachi 0A59577 320 gb disk drives reporting high pending and reallocated sectors causes system to crash.Vibration 10-200mz


> high pending and reallocated sectors

The electronics inside the disk-drive is encountering "bad" spots on the surface of the disk-drive, and is attempting to allocate some of the "spare" parts of the disk-drive as substitutes for the "bad" parts.

But, it is running-out of "spare" areas to deploy.

What this means is that YOUR DISK-DRIVE IS ABOUT TO FAIL.
Buy an external disk-drive, or buy a bunch of CD-writable or DVD-writable disks, and make a BACKUP copy of your files (E-mail, music),
while you still can access your current disk-drive.

Then, buy a new "internal" hard-drive, and reinstall Windows (you *DO* have the "System Restore" disks, correct?) onto the new disk-drive, and restore your files from your backup.

If your current disk-drive is still under manufacturer's warranty, then exercise the warranty, to get a free replacement. But, make sure that you have copied all your data from the disk-drive *BEFORE* you send it to the manufacturer, because they will take *NO* responsibility for trying to "recover" any of your files.

Cannot Copy the File P3.sys


Hi,

Try to check your hard drive. Use a utility tool specially made for the manufacturer of your hard drive. Ex. Seagate Hard Drive = Seatools
Western Digital = Data Lifeguard.

Check for any errors or bad sectors on the hard drive

My maxtor external hard drive has done a scheguled Plan b backup but files that I removed from my master hard drive to free up space because I had them saved on my external hard drive are now missing from...


When a file is delete, it's still there on the drive, just as before; all that happens is that the file table marks it as free space and changes its name so it's no longer visible. There are a number of "undelete" utilities available, including several good ones, like asoftech data recovery that helped me before:

Stop code 24


ErrorCode 24 is for corrupted drives or boot partitions

  • Boot the operating system CD
  • Enter the Recovery Console by pressing 'r' when prompted.
  • Then from the command prompt run "chkdsk C: /f"

  • OR....if that doesnt work..

    Inside your hard drive are typically 2 ~ 4 discs (called "platters") stacked on top of one another, and read / write heads between each platter which collects or writes information to the drive. Because a hard drive platter sits *extremely* close to the read / write head of the drive, a single particle of smoke traveling between the two could cause the head to crash. That being said, bad sectors on the drive may be a result of corrupt medium (perhaps as a result of a warped or chipped platter, for example).
    The disk repair utility in Windows XP, called ChkDsk ("check disk"), has an option to "scan for and attempt recovery of bad sectors". However, what may end up happening is that ChkDsk will mark the sector as bad (instead of attempting to recover any information) and your hard drive will no longer 'hover' over top of that area of the drive, making it impossible to recover any data on the sector.
    What you should do is:
    1. Attempt to backup all critical files on the drive (such as your documents, favorites, pictures, and anything else you can't download off the Internet or replace elsewhere).
    2. Following that, run ChkDsk and attempt to recover bad sectors. To do this, go to My Computer, right click your hard drive (C Drive?), select Properties, then goto the Tools options menu, and select "Error-Checking". A new window will appear. Select the option "scan for and attempt recovery of bad sectors".
    This test will take a while to complete.
    If ChkDsk reports a lot of bad sectors, visit the hard drive manufacturer's web site, download a drive integrity tool, and test your drive. To find out the manufacturer of your drive, right click My Computer, go to Properties, go to Hardware, then Device Manager, navigate to Disk Drives, and collapse the menu. Your drive should be listed there. If not, open up your computer and have a look.
    If the integrity tool reports many errors on the drive, you will need to ship it to the manufacturer for replacement (information for this procedure will be on the manufacturer's web site

    Windows will not recognise my Iomega LPHD 160-U external hard drice.


    1. Start > Run > type in cmd then click OK to get a command prompt.
    2. Type in chkdsk e: /r (replace e: with the drive letter of your external hard drive).

    This won't do any harm, it will fix errors on the disk and try to recover data from bad sectors. It might not solve the problem but it's worth a try.
