Dual hard drive gets "lost"
I have a 64gb ssd as system disk and additionally a 500gb hdd as data disk in a pata optical bay enclosure. all works great and quick, but randomly after awaking from sleep mode the data disk is "lost". not visible in finder, not visible in diskutil. after a restart the data disk is here again. disk check with diskutil or DriveDx show no errors on the disks.
Is this a good question?
