Subject: More cleanup of the SMART ATA passthrough commands
X-Git-Url: http://git.xnk.nu/?a=commitdiff_plain;p=JMraidcon.git

More cleanup of the SMART ATA passthrough commands

SMART data gets received in the same format as the drive normally
emits it, but with the command header still present (meaning
the actual drive data starts at offset 32)
