My fathers Compaq desktop's hard drive puked out on him. I am considering replacing it with a used one. The guy he took it to told him that Compaq is fussy about the hard drives. I would assume this is a mobo issue if it is even an issue at all. I do not know what model of Compaq he has, I haven't gotton it back from the guy he took it to yet. I do know that it has a floppy, cdrom, basic ports on the mobo (nothing fancy), no usb in the front. It is an AMD K-6 II 450 with a 6.4 (I think) hard drive. Anybody have any ideas on this one?
