Last week we got a real read error reported on the disk
(with a useful log entry, finally), so we arranged a
replacement disk.  It has been working flawlessly so far.

So maybe it was really the disk causing the trouble.

However, the strange thing is that _no_ ATA errors were
logged at all previously.  If gmirror disconnects a drive
because of ATA trouble (i.e. a read/write error), I would
expect that the ATA driver should report that read/write
error, shouldn't it?

Best regards
