Hi!

[Replacing Mylex RAID adapter with Symbios SCSI adapter]

My thoughts exactly. Maybe if the disks on old controller were 
configured as JBOD (no RAID) it would work, but if they were 
configured as RAID array then I think that only the Mylex adapter is 
able to adequately read the partition(s) on the array.

I'm not such a big RAID expert either, so of course my thoghts are 
worth exactly what you paid for them :-)
