I keep getting various errors when trying to a) eject one of my external RAID arrays, and b) empty the trash, which contains files from said RAID drives. It gives me an Error -50 when trying to empty the trash. When I try to eject the external drive it says it can't because it's in use. Using the lsof command in Terminal reveals that Finder is "using" the file. What the hell? Any ideas? This is ridiculous. On my rMBP, for what it's worth.
