LTR-40125s not working

I have an external IEEE 1394 (firewire) LTR-40125s (the external casing is made by Oxford Semiconductor I think) that connects to a FireWire PCMCIA adapter card. It doesn’t burn, and doesn’t automatically read media, so I 2x clicked on the E: drive icon; even though there was a cd inside it said ‘please insert media’, so I opened the device manager-- the burner is shown under ‘Disk Drives’ (instead of dvd/cdrom drives) as ‘Oxford Semiconductor Ltd. OXFORD IDE Device IEEE1394 SP2 Device’ and under "SBP2 IEEE 1394 Devices’ as ‘SBP2 Compliant IEEE 1394 device’. The drivers it is shown as using are ‘disk.sys’ and ‘partmgr.sys’ for the first category, and ‘sbp2port.sys’ for the second. I think the problem is that it the computer is not reading the drive as a CDRW at all, but as some other sort of disk drive. Any ideas on how to fix this?
