Hi Gordon,

Is there any particular Reason, why a mainboard failure should result in 
massive data loss?
But you can be assured, that a disk failure in such a volume will most 
certainly result in massive dataloss, since the filesystem spans across 
all disks.
Is there any partuclar reason for using truecrypt?
