I have a known working Maxtor 160gb hard drive loaded with XP. However the motherboard on this PC is working intermittantly. I have been given a working Compaq evo PC with a western digital wd400 hard drive also with XP. I would like to use the Maxtor hard drive with the compaq instead of the western digital one. If I remove the western digital drive from the compaq and replaced it with the Maxtor hard drive, then the compaq recognises that the hard drive is now a maxtor. A message appears on screen asking to press F1 to save these settings. I press F1, the screen goes blank but the PC does not load into XP. I have set the links to cable select and also master but get the same results. Any ideas what the problem is ?
