Subject: Computer can't see 1TB USB drive

I have a 1 TB sata drive formatted with Acronis as a single logical NTFS
partition. I formatted it via USB using a Vista Thinkpad T60. The drive
works fine on the Vista T60. When I connect it to an IBM ThinkCenter XP
desktop, it is not seen. The little bell sounds indicating it is connected,
but no notice on screen, and not seen by Explorer, Disk Management, or
Acronis. The desktop bios is latest Jan 2008. The desktop has a
larger internal 1.5 TB D: drive which works fine.
Can anybody help me get this workng, or tell me why it won't work? Thank you
very much.
