My system is a mid 2007 24" iMac with OS X 10.5.7.
The internal superdrive was giving me problems, so I took Brains' advice and purchased a USB 2.0/firewire 5 1/2" external enclosure ($75 for a nice solid aluminum unit
Adelong Computers Zynet 5.25" External DVD Burner USB+Firewire IEEE1394 (240V Powered)) and an LG GH22NP20 burner unit (called a SuperMulti burner).
It assembled easily and was recogised by OS X. I've connected it via the firewire 400 port. System Profiler identifies the drive as having burn support (generic drive support).
The drive reads disks perfectly well but I haven't been able to burn DVDs in the finder or with the "Burn" application. It all appears to be fine until I press the burn button, when the unit reports that there is "insufficient space" on the disk. This problem is also reported by others at
Apple - Support - Discussions - DVD burning problem LG Super Multi- .... When I use Disk Utility to examine the drive it says "Burn Support - Unsupported".
I've tried moving the jumper on the drive from master to cable select, but still no success. The drive's firmware version is the most recent from the LG web site (v1.03). Does anyone know for certain whether this particular LG drive model works with OS X?
The drive performs and burns perfectly in Windows 7 RC1 when I boot up the same iMac via Bootcamp. It uses the Microsoft generic driver.
My guess is that the Apple generic driver does not support the drive as well as the windows generic driver.
If I have to get another burner unit, can anyone recommend a 5 1/2" unit which they know is fully supported by the current Apple generic driver.
