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.
