SATA drive installation

My brother has reformatted his PC and put windows XP back on. The drive that windows is on is IDE (C drive). Since reformatting the PC his second hard drive which is a SATA drive is not being recognised. It is not being recognised in the BIOS either. All the cables are correct.

What do I need to do to get windows to recognise the SATA drive? The SATA drive contains important information that cannot be lost so the fix cannot including reformatting the drive.

Motherboard = Chaintech 7NJS

SATA drive = Seagate Barracuda 7200.7 model ST380013A8

The PC does not have a floppy drive. Has a CD player and DVD re-writer.

i thought the problem was the fact that XP by default can only regognise upto 137Gb HDD but, because your SATA HDD is only 80Gb that is not the case you just need to tell XP you’ve added another HDD by: Control Panel > something like admin tools (if visible) > storage > right click on unallocated space, format & assign space to a drive letter

sorry i’m a little vague, but, i don’t & haven’t used XP for a while now
