Hi and Welcome!
your computer has a Via chipset. Unfortunately, the Sata controllers of early revisions of Via 8237 southbridge are not very compatible with optical drives.
Return the drive and get one with P-ATA interface or
Buy a [I]non-Raid[/I] Sata controller PCI card, preferably with Silicon Image chipset (3512 or 3114) or a Promise controller.
Some Raid controllers with Silicon Image chipset can also be converted into the non-Raid version, see here: http://club.myce.com/f7/silicon-image-based-sata-ide-controllers-flashable-not-252721/
