I just bought a Lite-On 48x12x48 CDRW and put it in a FireWire case, which was originally from a QPS Que! 8x CDRW. Mac OS X doesn't recognize the drive at all. I also had a 32x CDRW in the case a few weeks ago, and it worked fine, so I know it's not the IDE->FW bridge that's causing problems (limiting which drive can be used or anything). Toast 5.2 doesn't recognize it, either. What's going on? Do they have drivers for X?
