Hi All,
I want send Passthrough commands which are 32 byte like Read-32 (SCSI
Block command - section 5.11)
Both SCSI_PASS_THROUGH(defined in ntddscsi.h) and SCSI_REQUEST_BLOCK
(define in srb.h) structures in windows DDK have
UCHAR Cdb[16];
Please let me know how to send 32 byte CDB from windows application.
Regards,
Vijay Anand

I don't think Microsoft has implemented support for 32 byte CDB's yet. Our
solution was to implment a custom IOCTL to which we sent the 32byte CDB, then
issue another cdb using a standard scsi-pass through SRB. The driver would
detect this and convert the 16 byte request into a 32 byte cdb. To do this
you will need access to the driver source and have HBA hardware that supports
32byte CDB's.
