It is my understanding that fsck will only check 1 drive on a bus at a
time.  I see this with my IDE drives.  You said that you only see about
1/2 a dozen start up.  Are you sure this isn't *5* (one on each SCSI
bus)?  And then when a drive completes, another on the same bus is then
scheduled?

Isn't this list for Fedora Core questions?
