|You telling us you have a new Sony RW drive without telling us whether it's IDE or SATA doesn't tell us much - quote the model number. |
Requirements for an optical drive, and the disks it can recognize, to be recognized properly in XP.
See response 4 in this - the same applies for disks that are not blank:
ADVENT 3219 desktop specs and info
If you haven't loaded the main chipset drivers, you must load them.
Info at the end of those specs tells you where to load drivers from if you have the Recovery disks for the computer, or if you don't have them, it has a reference to where you might be able to get them.
OR - you can search of the web for: SiS661FX drivers
AND - SiS964 / 964L drivers
According to that info, your computer model did NOT originally have any CD-rom ONLY drives.
Lite-On XJ-HD166 16x(48x) DVD-ROM
(CD-rom and DVD-rom, or CD-RW [CD-rom and CD-RW] and DVD-rom; can't burn DVDs)
Lite-On LTR-52327S 52x CD-RW
(CD-rom and CD-RW; can't read or burn DVDs)
Your mboard has two IDE data cable headers, and two SATA data cable headers.
The main chipset supports only the original SATA specs - up to 150 mbytes/sec max burst data transfer speed. If you install a hard drive with SATA II specs ( up to 300 mbytes/sec max burst data transfer speed), the mboard's chipset may recognize it anyway and run it at up to 150mbytes/sec max burst data transfer speed, or it may NOT recognize the drive at all, unless you install a jumper on the drive to limit to the original SATA specs - up to 150mbytes/sec max burst data transfer speed.(No SATA optical is capable of SATA II specs. There is no advantage to installing a SATA optical drive in comprison to an IDE one, other than convenience - the max burst data transfer speed is never faster than 66 mbytes/sec.)
It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittent, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.
Try another data cable if in doubt.
Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)
The same thing applies for the SATA power connection.
If you install a SATA hard or optical drive,
- if the bios has the SATA controller set to SATA mode (a.k.a. AHCI mode) you must install the drivers for the SATA controller in Windows.
- if the bios has the SATA controller set to an IDE compatible mode of some sort, then you don't need to install the drivers for the SATA controller.
