Ive got a 80gig maxtor hdd as my slave. the master is the 40 gig that came with my HP computer. Right now XPpro isnt detecting that i have the 80gig slave connected. when i put my old other 80 gig as the master then xp detected the slave. but i switched back to the 40 gig master and alas, no slave. any idea what could be causing this?
