hi ya
best way to test raid5 is to write large ( 1Gb-2Gb ) data files to it...
and than compare the files....
-- oooppss... just re-read david's post.... skip the part about
powering down the disks..etc...
than pull one of the disks offline....
and see if it still compares...
insert a fresh disk in its place...
and see if it re-syncs while you are creating a new "large file"
-- for testing raid1 mirroring...
- write to "A".... and take "a" offline
and see if the mirror ( "B" ) has the data you just wrote
taking scsi drives offline is tough ???
taking ide drives offline is easy ... use hdparm to shut it down ???

=== best way to make sure you dont lose the data on the Raid
=== is to have a backup somewhere else...

have fun raiding
