Did you figure this out? I’m having a similar problem with my 24" Intel iMac. The old driver broke, so I replaced it with the AD-7630. I works great, burns and reads DVDs, but after a burn, I can’t eject the CD. Also, can’t launch any new apps and have to reset the iMac. It appears like some kernel thread/driver gets hung.
Any insight appreciated.
I put all energy saving stuff to “off”, but the behavior is the same. After a while, the drive will still be visible in the system profiler, but it won’t do anything else.
I went by the store I bought it from to test it there, and they face the same problem with 3 different units, so it is not a bad drive.
While I was there I noticed that the new iMacs have the Optiarc AD 5630 drive (which aparently works) and comparing the two I saw that in the System Profiler Report: Low Power Polling the 5630 has “yes” but the 7633 has “No”.
Does anybody know what is that Power Polling thing and if it is fixable by a firmware or a kext tweak?
And a second one: Is there a chance of crossflassing the drive to a 5630 (probably not I presume)?[/QUOTE]
