However, it works in neither cases. Attempting to dd from the drive results in a "dd: /dev/da0: Invalid argument". FYI: I had been experiencing the same with a 2 TB WD MyBook on OS X (Mavericks). The drive was being used for Time Machine backups, but it would at irregular intervals it would just 'disconnect' itself. My guess is that there's a firmware problem in the USB3 chip in those drives. After trying to get the issue fixed for almost half a year I returned it and replaced it by a Seagate, which has been working flawlessly ever since. I'm just saying, perhaps the problem isn't with FreeBSD but with the drive. Cheers.
