According to the linux RAID HOWTO...
http://www.tldp.org/HOWTO/Software-RAID-HOWTO-4.html#ss4.1
'It is very important, that you only use one IDE disk per IDE bus. Not
only would two disks ruin the performance, but the failure of a disk
often guarantees the failure of the bus, and therefore the failure of
all disks on that bus.'

Then again, the HOWTO is somewhat out of date.  Perhaps dieing disks
killing the bus is just folklore?

Haven't really helped, have I? :)
