I've got a very maddening problem!
The motherboard in my old HP computer died and I have got 40 GB worth of data on the hard drive that is still working.
I got a new XP computer and added the old hard drive as a slave, to get the data out, but apparently the old XP program is locking me out!
How do I get around this block, so that I can get onto the old data, to save it, and get it ready to be reformatted, for use in another computer?
