So I got a new DVD+-RW drive a while back.  It was working perfectly for a while, and then it suddenly ceased to work.  The drive SHOWED up in Windows and BIOS and such, but it just wouldn't work....  I left it alone, hoping things would GET better, but no luck - in fact, it got worse...  The drive ceased to show, and BIOS stopped detecting it as well, and not only that, but it began to crash my computer.  I just disconnected it and left it alone for a while, but today, I decided to give it another shot.  I cleaned out the whole thing, and connected it.  BIOS now detects it and Windows can find the drive, but it won't read ANYTHING =\  I looked for drivers (No luck) and I installed the newest firmware, and tried everything I can, but it just won't read disks.  Can anybody help?

It's a NU DVDRW DDW-082, and I'm running XPSP2 on a 2.4GHz P4 with 512MB RAM.  ANd oh, btw, the IDE CABLE is good - I tried switching the Master/Slave, but the CDRW drive still WORKED, yet my DVDRW drive still wouldn't.  Any help or suggestions would be appreciated =]
