Bad Sectors: Problems with chkdsk/f

    I have lots of bad sectors and not even able to do a restore to a previous
    restore point. I tried chkdsk/f but on restart it doesn't do the chkdsk. I
    have a Vista repair disk and I ran the repair but I still have the sector
    errors that prevent going to the previous restore point. What should I do?

    I have not had todo this, but you can boot from the install cd and run a
    command prompt.

    I think its called the Recovery command prompt.

    This should allow you to /f you OS disk as it will not have any locks.

    see

    http://www.bleepingcomputer.com/tutorials/tutorial147.html

    for info on how to boot to this command prompt.

  4. You're talking apples and oranges. Going back to a restore point does
    nothing to fix bad sectors.

    What might be happening is the bad sectors are on your root (C drive)
    and since you try to tell Vista to fix it AFTER you are already
    running Windows they never get fixed since Windows is already in use
    and the drive is locked.

    The only way to fix bad sectors and other file system errors on your
    root drive is do so BEFORE the system boots the operating system.

    The procedure is:

    1. From Windows Explorer locate your C folder, right click, properties
    tools, then tools tab.

    2. Under error checking click check now, then select automatically
    fix file errors.

    Since you are already in Windows the request will fail but Vista
    should ask if you want to schedule it to run at next boot. Say yes,
    then immediately reboot. You should see a pale blue screen that takes
    three steps running right after you see your normal boot screens but
    before Windows itself loads. This should correct the problem.

    If it doesn't repeat steps 1-2 but also check scan for and attempt to
    repair bad sectors. This can be a VERY slow process so best to do when
    you don't need the PC for hours, like a long lunch or overnight.

    If you still don't resolve check on Google for several how-to sites on
    how to force more advanced uses of chkdsk from a command prompt using
    different switch settings.

    The good news is the NTFS is self repairing and can repair all but the
    most severe file system problems. It just is getting it to do it
    sometimes.

  5. IMHO the only way to fix bad sectors is a new drive. Large numbers
    of bad sectors almost always (well, actually, *always*) indicates a failing
    drive.

  6. Yes, but try to get what data you can off the thing first. I've had
    varying success with SpinRite, haven't used it in years, it use to
    address one of the main mechanical reasons why hard drives "fail", the
    read/write heads drifting out of alignment. I think they have a NTFS
    version out. While somewhat expensive and slow (can takes days) far
    cheaper than any of the services that offer to recover lost data. In
    fact many of the firms that claim that use SpinRite themselves.

    The reason it works is it totally bypasses the OS and reads a hard
    driver sector by sector tweaking head positioning to recover what is
    possible. Often the only time you can't recover data is if the drive
    won't spin up. Such drives are usually not worth messing with.

  7. Nahhh, toss it and restore from backup :)

    Conner drives used to lock up when the spindle bearings froze,
    and you could get them moving again by picking them up about shoulder
    high and dropping them on the desk.


    I once got an IBM disk to spin up by shaking it real hard, inspired
    by those old Conners. Did the customer thank me for getting their RS6000
    to boot? No, they complained to my boss that after I'd recovered their
    filesystems their Oracle database was corrupted.

    I've had good luck with a program called restorer2000. It has a demo program
    that will allow you to recover small files. The full version costs $50.00.
    The best way to recover data from the bad disk is to in stall your OS on a
    new disk and then mount the bad disk as the second drive and run
    restorer2000. when run it gives you a windows expolrer type display of the
    disk. then you can click on files and try to copy them. It will tell you if
    it can copy the file or that it may have trouble copying the disk, or that it
    can't copy the disk.
    Good luck
