The RAID kept breaking with a RAID integrity error. I thought one or both of the drives was bad, but they work fine individually prior to the RAID and have worked fine for years individually after I stopped using them in RAID. I still use them today.
I'm not sure what the problem is, but Googling found this:
...which mentions Greens use some sort of frequent "Intellipark" idle method that, perhaps, is bad for RAID on non-Windows operating systems.
