Anyway - what exactly happens when a PATA harddisk dies? Will this only lead to logentries in the syslog, or will this crash the machine due to hardware reasons? Probably there would also be a difference if you would do RAID on the same channel (e.g. hda, hdb) as a mulfunction of one device could jam the whole IDE channel. The same thing can apply to SCSI, too - I once experienced this myself when a fautly SCSI-CDROM jammed the whole SCSI-bus and crashed my machine. I hope that SATA will be a lot less critical, it should support hotplugging (at least with SATA 1.1, it's a pity that it's not supported with 1.0 right away) and there is only one device per channel.
