Is this a USB HD ? 2.5" hard disk.
I do not realise people can still buy 3.5" harddisk so small.
Usless you are using a 4-5 years old PC (pentium 2 or P1) this should not be bios problem.
If using Win2000 or Window XP
after you plug in the HD
press start > run > type compmgmt.msc , press enter
In computer managment click disk management (second last on the left)
choose the disk you want on the right screen, left clik to delete partition then recreate partition than do quick format.
XXXXXPlease make sure you choose the correct HD before proceed else you delete the wrong HD no person can help you.XXXXX
or you can use programme like partition magic or Norton utilities to help
Also Ghost have a programme call gdisk.exe or gdisk32.exe whcih can help
