recently i bought an 80 external HD. I am running windows XP, the day i bought it it worked fine, it showed up next tt C drive in my computer and everything...later that night i noticed that it wasn't there anymore...i have read dozens of forums trying to figure out what is wrong. i have checked the device manager and it says that all drives are working properly, but it doesn't even recognize that my HD is plugged in. I have also explored around administrative options, but it also does not even show up in there! I am not incredibly intelligent when it comes to comps...so any help that anyone could give me that would be easy to understand would be awesome...PLZ HELP

note: the HD came with an install disk, but nothing on it seems to work...
