I have an IBM Aptiva model 2176-C55, And I am unable to format the HDD using the "FDISK command" in DOS 6.22. I get a message saying "error reading fixed disk". I am certain that the HDD is working as I've hooked it to another PC, and I've checked all cable connections from the Drive to the motherboard. The hard drive is a Western Digital WD800BB, and I have the jumpers set to primary. My issue is that I cannot get the PC to detect a HDD in the BIOS, and I cannot run the FDISK command to format the drive. If anyone is familiar with this system, any help would be greatly appreciated. Thanks!
