How can I access a hard disk with a bad partition?

Shakirah Faleh Lai May 9, 2012

How to skip a bad partition in a hard disk? I have installed a 40GB Samsung hard disk, but the desktop can’t read the hard disk. Someone told me that the hard disk can be used again if I skip the bad partition.

    First of please make sure that the BIOS recognise the HDD. Change the boot sequence and choose DVD Drive as ur 1st boot drive.
    Insert Hiren's Bootable cd ( for more details and download) and choose Darik's Boot and Nuke option. And proceed with the onscreen details.
    It wipes the whole drive with no recovery option.

    PBD(Partition Bad Disk) may be useful to solve your problem

    Use other bootable software for recovering/backup of your important files. Im using hiren bootable cd. This tool is very handy and easy to use. There are also lot of useful tools included which you can use for repairing some other problem. You may also want some idea i can refer you this

    You're not trying to recover, just use, correct?

    If the bad sector is at the front, where the partition tables are stored, the drive is junk. Bin it and do something else.

    The information you have been given is inaccurate. Perhaps your informant meat bad *sectors*. At any rate, if you are willing to erase the disc, then you can do a "full format" which will force the hard disc controller (part of the hardware) to "map out" the bad sectors. There are several ways to do this, here's one:
    - In "Computer" ("My Computer" in Windows XP), right-click on the drive
    - Choose "Format"
    - Make sure that "Quick Format" is NOT ticked, and click [OK]
    - When the formatting is complete, [close] the window. The disc will be ready for operation.

    If the disc does not appear at all in "Computer", let us know and we'll suggest an alternative method.

      The disc does not appear at all.

        In that case, best follow Mike and Rob's suggestions.
        Ha14 is also right, but unless you need to recover data, it's not a good idea to try to revive a sick disc, certainly not with software that costs as much as a new disc!
        Laga also makes a valid point, but how would you know which sectors are bad without high quality diagnostic software (or a lot of knowledge)?
        Hard discs are mechanical, and degrade over time, so given that a 40GB must be quite old, I would suggest repairing it only if it can be done easily and cheaply.

    you can try to scan hard drive with spinrite to correct the partition.

    You can try booting your computer with a Linux Live CD. You can use Ubuntu or I would suggest using "Puppy Linux"

    Download lupu or slacko, after buring the ISO to or CD you can boot your computer with that, you can access your harddrive from there, you can also adjust the partition using "g-parted"

    I'm not sure what is meant by "skipping a bad partition".

    You can try to
    - repair it e.g. using Easus Partition Recovery
    - recover data from it e.g. using TestDisk

    or if you just want to use the drive again (regardless of the data that may or may not be stored on it) simply format it.

      I should say bad sector, sorry I'd confused you.

        Usually bad sectors shouldn't cause a problem. Once they are marked weak/bad they will be reallocated automatically be the hard drives controller.

        Again, if you just want to use the drive and don't need any data currently on it you can use the regular format (instead of quick format). During that operation the hard drive is being scanned, bad sectors are detected and will be reallocated.

        If it's a "live drive" with usable data on it you could use a tool that offers a surface test. During this process again bad sectors are detected and reallocated. Some examples:

        EASUS Partition Master (free Home Version)

        SeaTools (for Seagate and Samsung drives)

        Data Lifeguard Diagnostic (for Western Digital)
