I am selling an old 20GB hard drive to a friend for 30$. I need to check to make sure this is the right drive out of three of them because one is a back up drive with some important files. I should sell this early Tuesday afternoon.

I have not been able to find out which drive is which. I know which drive the back drive is but I want to make sure before I sell the other one.

Maybe I'll just sell the the drive in the Win98 box now because I am sure it is not the back drive. The back up drive must be the one with the slave setting on the jumper.
