    Bad sectors are portions of the hard drive that are unreadable.

    They usually multiply, and eventually the drive will completely fail.

    But, how long that will take depends on what caused the bad sectors. If it is just a manufacturing defect, then it may be years. If it is a piece of dust inside the hard drive, it could be weeks.

    Bottom line... Backup everything on that drive that is important to another drive.

    As 'Bjorn' indicates, those are tracts that (for whatever reason) can no longer support the read/write function.

    Hard drives are made with 'backup' sectors for migrating data from failing sectors; that's one reason you see advertised 500Gb drives, but installed, they only have 480 Gb usable. (the amount varies between manufacturers).

    SMART is the built-in drive firmware for detecting these failing sectors (and some other technical evaluation 'stuff').

    The 'checkdisk' operation should be done once a month to determine pending failure of these sectors, which will enable migration before total failure of the 'read data' function.

    Data backups should be done routinely, irrespective of the condition of the drive.

    Imminent failure is NOT the time to perform BU's, as the added strain on the mechanical aspects of the drive could well fail, leaving you without data.

    No, it does not. you are able to attempt reinstalling the working device. XP or Vista will test thechronic for errors earlier than setting up. they'll "tag" the undesirable sectors so as that no tries are made to place in writing to them interior the destiny (hence not producing errors). it extremely is approximately all you're able to do without appearing a low point format (which does not fix them ... in basic terms hides them completely). FYI - low point formatting isn't for pc beginners. you would be able to desire to very actual render the HD completely unusable. regards, Philip T
