SCSI_DISK_DRIVER_INTERNAL

SCSI_DISK_DRIVER_INTERNAL is bug check 0x2D. Microsoft describes the code as very infrequent and does not publish meanings for its four arguments. The name places the stop in a SCSI disk-driver category, but it does not identify a target, LUN, SCSI status, sense key, or failed command in a documented parameter field.

Do not manufacture SCSI sense data from the arguments

Sense information and storage-request details have their own structures and logs; the public 0x2D contract does not map the bug-check arguments to those fields. Use the dump to establish the active storage stack and the driver routine involved. Then correlate with storage diagnostics only when the captured path supports that direction.

What to collect

Keep the exact stop arguments, Windows build, storage driver versions, and original dump.
Run !analyze -show 0x2D and !analyze -v, then inspect loaded storage-related modules on the stack.
Compare system or storage events around the crash as supporting evidence, not as replacements for the dump context.
