Yeah, I would say that you have either some bad hardware or a bad driver. Drivers that sit at the kernel level that can not be paged out can cause a blue screen if something goes wrong. You can post the bytes here and I will see what I can do.

The lights on the HDD array are green in OK status. Adaptec told me Adaptec
Storage Manager will not work with Windows 2003 Server and that this was not
a problem with their SCSI card. The OS is not part of the RAID array. Only my
Exchange Program Files and DB are on the D: drive raid array. Because the C:
is not part of the raid array, would this rule out the SCSI raid system as a
cause of the problems?
I continue to get a "unresponsive system" in which there is only a black
screen. The problem has grown from intermittent reboots in which the server
would come back online to the unresponsive black screen with no error
messages other than the dpti2o. I have to manually power off and back on.
After restarting, I see the window where you choose what happened such as
"power failure" or "system unresponsive" and then log in. There is no error
code or message displayed anywhere.
I have seen the Blue Screen of Death only once. It led me to this info from
its error code...
0xC0000185 STATUS_IO_DEVICE_ERROR, caused by improper termination or bad
cabling on SCSI devices.
I reseated the SCSI cable and termination appears to be correct. My gut
feeling is this is a hardware issue, but I can't nail down which component is
failing.
Are there any resources online to interpret the System Log Event Properties
DATA that is displayed in BYTES?

I would look at the Adaptec Storage manager if you are using it and inspect every disk that could have possibly generated a log entry about any Bad SCSI statuses. You should see a SCSI status similar to this output below:
Bad SCSI status - Check condition
28 00 02 D3 31 00 00 00 80 00 00 00
NOTE: If the first byte is the SCSI Status (0x28), then this indicates that the drive's Queue was full and it could not accept anymore I/O requests from the controller.
and
Request Sense
70 00 06 00 00 00 00 28 00 00 00 00 29 02 00 00 00 00
Unit Attention
NOTE: The 12th & 13th positions indicate the important response from the device - in this case 29 02 indicates "SCSI Bus Reset Occurred".
Do you have any drives that have orange or red lights on them as this would indicate a problem with that drive in your array? You might be able to look at this: http://www.moojit.net/Networking/downloads.shtml. I have never used this utility but you can give it a whirl.

Regarding the \Device\Scsi\dpti2o1 message, does the 1 at the end of dpti2o1
relate to hard drive 1 in my array?
