Firewire DVD burner - works in OS 9 to Leopard, not in SL

Hello!

A while ago, I figured that it would be nice ot have an external DVD burner - as one that I wouldn't disturb via vibrations when using my MBP, and could use with my old Macs without a burner.

This burner is an NEC DVD+/-RW DL burner, as listed below. I pulled it from an old windows computer that died, and placed it into an older LaCie FW 400 enclosure. Under the older OSs - Tiger, Leopard, even OS 9 in CD-burn mode - it worked just fine, and could burn all supported formats without difficulty. In snow leopard on my 2.2 Ghz MacBook Pro (Late 2007), not only will it not function as a burner, but OS X itself does not recognize the drive. That is, System profiler detects the LaCie enclosure, but as far as SL is concerned, the enclosure has nothing in it. SL doesn't see the DVD burner, and neither does Toast. I tried placing a commercial DVD-ROM in there, but OS X wouldn't read the disc either.

Do you know how I can fix this? Or, is there really nothing I can do except use it with the older Macs? It worked fine with this same MBP before the update to SL for what it's worth...



Thanks,

-Dan

Interesting! I'll have to try that.

I finally got chance to mess around with the drive and such, although I haven't tired this. I actually discovered one fix, described here:

It works perfectly, although I don't much like having to use an old version of the extension. Still, everything seems to work well, so that takes care of the problem.

Of course, next time Apple updates the OS, that may change...


Chen: I'll have to give this a try at some point, although it's quite odd that SL would recognize a drive if booted with a disc in it, but not otherwise. Go figure!

Thanks for the help everyone

Rebooting with a dvd inserted sometimes did help. But mostly not. But:
I can confirm - updating the firewire-firmware in my LaCie dvd burner (1.05) solved the problem completlely.
(The funny thing is: this update is pre-SnowLeopard ! So maybe the older LaCie firmware was not a perfect firewire implementation, and Snow Leopard's implementation is too strict. But that's guessing...)

My 5.25' firewire enclosure was Taiwanese made and 9 years old. But the DVD-RW was Pioneer and 2 years old.

My 5.25' firewire enclosure still not work (the only way to use it was just insert a CD in it then boot my Mac). I think the Apple engineer of Snow Leopard never test with OLD (at least 5+ years) firewire enclosure, so they didn't found this problem.

The Lacie enclosure user were the same. If you guy never update the firewire enclosure's firmware, your Lacie just like a 5+ years old box, but once you update your Lacie box firmware, the box was a newbie one.
