Have you ever had a friend ask you to recover data from a "bad" hard drive?
I have a Win2K box with 2 hard drives. I've told him that I can pull out my 2nd hard drive (not with my bootable partition), put his 2nd hard drive in, and use utilities to recover his data. I'll then burn it to DVD's for him.
My question: what do I have to do before hand? Or will the O/S not be confused when suddenly it sees that the 2nd hard drive is different with different partitions?
