Hard drive wont show up in disk manager/my computer

Ok, so I have had this external for about 3 years now, and I have never had any problems, its always been used on a windows system, but gone through xp vista and now I’m using windows 7. Yesterday I was at university, the drive had been plugged in for about 12 hours in a really hot room, but was running fine, my friend asked me for some files and plugged it into his Mac (dont know if this could cause any errors?). When I got home I tried to do some more work but the drive wouldn’t show up, It reads it as a mass storage device under device manager and it appears in the Disk Manager but when I try to initialize it I get an error saying : Virtual disk manager : Incorrect Function. Under the device properties in Printers and Devices it shows that the HDD has 0 space for all of the options. I was thinking about getting another case to test if that could be the problem but wondered if anybody else had any ideas? many thanks zef
