Dear smartmontools developers!

Until the very recent version of smartmontools (5.39), SMART through USB was not possible on Mac OS X, because the Mac OS X kernel does not support SCSI pass through (reasoning of Christian Franke).

Meanwhile I googled for: ​http://www.google.com/search?q=mac+osx+scsi+passthrough+usb

And found a person, who wrote a SCSI pass through driver for Mac OS X: ​http://tinyco.de/2009/02/04/writing-a-mac-osx-usb-device-driver-with-scsi-pass-through.html

In the site's comment section I asked as Stefan Nowak whether this code could be used for passing through SMART: ​http://tinyco.de/2009/02/04/writing-a-mac-osx-usb-device-driver-with-scsi-pass-through.html#comment-24129787

And the developer answered within the site's comment section as wagerlabs, that it should work: ​http://tinyco.de/2009/02/04/writing-a-mac-osx-usb-device-driver-with-scsi-pass-through.html#comment-24130057

I don't know low-level coding, otherwise I would offer my help. Please, dear Darwin related smartmontools developers: Could you built SMART through USB support into the Mac version of smartmontools?

Regards, Stefan Nowak

The ATA SMART RETURNS STATUS command provides the result in the ATA output registers. Buggy ATA/SATA drivers and SAT Layers often do not properly return the registers values.

If a SAT Layer does not provide an ATA Return Descriptor with the output registers, smartctl 5.39 prints the following message and aborts:

Error SMART Status command failed
Please get assistance from http://smartmontools.sourceforge.net/
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

Smartctl should not abort in this case and print a more specific warning message. The output for 'smartctl -H ...' should be as follows:

SMART overall-health self-assessment test result: UNKNOWN

I have a Lenovo (IBM Thinkpad) Modem T60 with an internal Hitachi HTS723225L9A360 that shows up as "Not in smartctl database". Attached is a log from smartctl -a /dev/hda
