Are the drives larger that 540Mb? Typical size for an older 486 , so you may need software to force the bios into larger drive access. Check the Quantum Fireball drive sites for thier bios patch. If no luck e-mail me at , I think I still have it. Otherwise check the bios settings to see if LBA mode can be toggled on. This would also clear the process. Checking cables and master/slave jumpers on the drives for correct positioning is all I can suggest.

Have you fdisked it yet? It won't detect it, unless there's a partition on the hard drive. Get a startup disk, then start the computer with the startup disk in. At the a: prompt type fdisk, then create a partition. Reboot, and it'll show the hard drive. Make sure you format it after you reboot. Just leave the floppy in and at the a: prompt type format c: and let it do it's thing.
