Make sure the ide cable has the hard drive on the end of it. not on the middle. Set the jumper to Cable Select (CS) or master it it is the only device on the cable. It should also be the Master on the Primary IDE port. Then boot into the BIOS by pressing DEL. Then change the boot order to Floppy,C,cdrom. Then go to the BIOS section for the Hard Drive. If it is on auto temporarily set it to manual. It should let you see the Tracks, Sectors, Cylinders. If it does set it back to auto. Try using a boot disk. If it boots use FDISK to see the Harddrive/partition information. You have to set up the Partition, etc, and format it.
There is always the slight chance you have the Cable backwards and are plugging the drive into the port plug. This will not happen if you never unplugged the ide cable. If you do not like my post feel free to point out your opinion or my errors.
