Hold on a second ...
Are you using a SCSI backplane?
If so, that's the difference right there!  ;->

SCSI backplanes and host adapters work very, very different
on transient (or failure for that matter) than _any_ ATA or
regular SCSI (without a backplane).
They are still formulating similarly for SATA, and there are
some SCSI adopted standards for SATA backplanes.
But with SAS, much of that is becoming moot.

Okay, now things make far more sense.  ;->
