SYMPTOMS
Under heavy stress or when restarting during Setup, there can be disk
corruption with a DPT caching SCSI host adapter.
This only happens when the write cache of the DPT adapter is enabled and
hardware level RAID 5 is used.
CAUSE
When there is a reset on the SCSI bus because of a timeout or a system
Reset, the Windows NT driver does not properly handle the uncompleted
commands in the command queue of the DPT adapter.
RESOLUTION
To resolve this problem, contact DPT for an updated version of Dptscsi.sys
or for information on updated firmware. You can contact DPT at:
