It works in this computer. and its hooked up right in my other. Maybe a new hard drive?????????
I cant really suggest much more cos Glasius has covered it but, take the case off, take out all of the cables connected to the drive and put them back in fully or you could swap the drives round, making it a slave and seeing if its being picked up then. Failing that, i think it might be time for a new drive...
Yah, run the disk as a slave on the computer its working on. See if you cant format it with NTFS there.
okay this may sound stupid.. but how is that gonna help my other computer????
if you format with NTFS you can run a checkdisc and look for erros on hdd. Not sure why the other machine isnt picking it up in BIOS. Faulty IDE cable? Wrong IDE port on mainboard? Run "Autodetect HDD" in Bios?
