Question on this... I noted that if I come up on the "fixit" disk, I can use atacontrol to 'create' a RAID1 array across two disks with ONLY the motherboard IDE controller! It also APPEARS to read/write to both disks - and if I disconnect one of them, intentionally "failing" it, it also appears to do the 'right thing' and keep running in degraded mode too! However, a "rebuild" (once one 'replaces' the dead disk) instantly returns and does nothing. Is it thus correct to conclude that the DRIVER abstracts the RAID1 function internally, and that the only thing you lose is the ability to replace/recopy the array? That is, in the event of a failure you could dump the remaining (good) disk, replace the bad, re-initialize the array and then copy it back - you'd lose "hot" rebuilds, but not the inherent protection of the mirroring.
