I have two older computers (about 8 years old) The one has a good hard drive with XP pro installed, but it has a slower processor in it. The other computer has a faster processor but the hard drive is shot. I tried putting the good hard drive into the other computer with the faster processor, but there are issues. I believe there is some trick or something I must do while the hard drive is still in the original computer, before I switch it to the other computer ??? I really do not want to wipe the hard drive and reinstll everything. Any help here, Thanks, Mike
