    Data recovery attempt using TestDisk


    Hello forum,

    I am attempting to restore lost data from an 80GB hard drive. Since I don't really want to deal with the lost data right now, I'd rather just image the drive and store it on my 350GB hard drive.

    I used the dd command to duplicate the drive to 80GB.iso. Strangely, I get different results between the drives when using TestDisk.

    On the physical drive, testdisk finds several lost partitions. On 80GB.iso it only finds a few. What explains the difference between these results? I am worried that the image of the hard drive won't be as good as the original.

    Going to give this advice a whack. Chrisophe is the main contributer to TestDisk.

    You may have to change the geometry (menu Geometry).

    If there are bad sectors, the option "conv=noerror" must be used.
