I just installed one of my Pioneer BDR-S09 sata drives in a Mac Pro (3,1).
All works ok, incl. burning, excep that:
The drive goes to sleep by itself. When this happens, the drive disappears from the Disk Utility, from Roxio toast and the whole system. One has to power down the system, reattach the cable and then the drive will show up again (for a while).
I've already set the Disk Sleep OFF in Preferences / Energy saver in OS X.
This has not solved the issue.
I do not have the same issue on the LG BH16NS55 sata drive. It keeps running and doesn't go to sleep.
So, is there a way to program the BDR-S09 drive internally (perhaps in Windows) so that it doesn't go to sleep?
Or is there an OS X hack that keeps a specific SATA device running by polling/accessing it in order to keep it awake?
