I am currently looking at this board for my first FreeNAS install. I had noticed on the NAS4Free forums that someone over there mentioned this device had trouble with hot plugging a replacement drive, and that it was a driver problem between FreeBSD and ASROCK. I was wondering if someone who had this board could test for this functionality with this board.
I have the board. No I can't test for you as it's not near me to test.
But *some* of the ports don't support hotswap. Not all, but some. I don't know which ones, but if you do some testing I know at least 4 of them do because the FreeNAS Mini has 4 bays and all 4 are *definitely* hotswap capable.
