Your best bet is is call your friendly Hard Disk retailer and as for a product
manual. This has worked for me from both retailers and Segate (Seagate in the
USA even sent me a manual!). Other manufacturers may call the book with SCSI
commands something other than a "Product Manual", but ask and thou might
receive. SCSI commands differ slightly from device to device.

The other avenue is to mail mr SRC@SCUZZY.UUCP (Heiko Blume) who at one point
mailed a very good article to comp.periphs.scsi. We only have it on paper here
and we don't want to type it in :-( .

Also, you might try to find a document describing the "Common Command Subset"
which most devices should support.

Happy SCSI'ing and try to avoid the "SEEK RECORD AND SCOUR DISK" command :-).
