Sorry for being unclear. I meant the disk driver, not ATA in general. I expected to get a bit more than the simple word "FAILURE" from a UNIX system. ;-) Typically a read or write error should be reported (along with the block number), or a time-out, or a DMA error, or whatever. Anything. But a little bit more than just "FAILURE". > The following gmirror error messages is then an expected > consequence. Yes, that's clear.
