okay so i just bought a new 250gb maxtor onetouch 4 mini hard drive. i installed the manager software on my xp partition but then when i boot into vista the hard drive doesnt show up. it says right on the back of the package that its vista compatible. is this because i installed in on xp? when i click manage under my computer in vista and then go to disk management it shows up but says its unpartitioned space. but im sure thats incorrect because it works fine in xp. so could someone tell me whats wrong? can i not have it working in both OS's?
