Bad sectors remain after frive copy

    Hi all

    My hard drive was developing bad sectors so I (using PQ Drive Image 5) copied it to an identical new drive. The original drive had 304KB marked as bas sectors - this had been increasing at the rate of 20KB per day.

    The copy was painless but when I ran chkdsk on the new drive it still reports 304KB in bad sectors.

    I'm guessing that XP is keeping a record of these and it hasn't reset the total. (I thought that it was the drive itself that was responsible.)

    How can I force XP to reset the total?

    It sound to me like your new hard drive is bad, too. ) If you can, try a
    third drive (even an old one you have lying around somewhere) so that you
    could be sure. It's not unheard of to find a second drive failing almost
    as soon as you install it.

    Some other things to check: You might simply be shutting off the power to
    Windows rather than shutting it down first. Sometimes that can corrupt the
    disk Also, you could have a bad power supply that doesn't supply enough
    power to operate your disk drive... but that seems less likely

    I don't think Windows keeps track of bad sectors on the disk. Typically,
    that is done internally on the hard drive and Windows is blissfully unaware
    of any sector problems (until it finds it can't read the drive).

    Good luck!

    From what I have found out so far:

    Legacy windows allows sectors marked as bad to be retested through a registry key change, ntfs stores bad sector information in the $BadClus metadata file.

    A disk to disk copy also copies this file and hence the new installation still believes certain sectors have failed.
