Also Id try going into your bios settings (F12, F10, whatever key your
bios uses upon booting) and running the disk detection part. some
motherboards (older ones?) dont detect new hard disks at each boot,
you may need to select auto for the ide channel that the disk is in.
I would tend to agree with vince though, if its not showing up on the
bios' POST then you likely have the jumpers set wrong - either both
drives on that ribon set to slave or both to master.
Also, you didnt mention if it is IDE or not, im guessing it is, but if
you are trying to set up SCSI disks or SATA disks then its a whole
different kettle of fish that Ive never swum (this a word?) in!
