the liteon SHW-160P6S showed up on the bios so that probably means the problem lies in the WinXP Pro x64 OS itself. In the device manager, I have uninstalled it and used the scan for hardware change.. it found the cd/dvd drive but with an error: "A problem occured during hardware installation. Your new hardware might not function properly." (or something like that) so I checked the detail info.. here it is: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Click Troubleshoot to start the troubleshooter for this device." okay I clicked the troubleshoot buttion and came up with nothing.
Any suggestion? Should I get a new cd/dvd burner drive (probably sata one like this one Lite-On LH-20A1S SuperAllWrite) I already have some extra SATA connections that came with ASUS motherboard box.
Edited: I forgot to mention that I did found a good working ATA IDE cable.. and replaced the old one with it.. still got the same result.
