According to http://www.seagate.com/support/disc/manuals/ata/cuda7200pm.pdf
this drive has SMART capabilities.
(AFIAK, all modern ATA/SATA drives have.)

I presume the controller firmware/driver modifies the returned IDENTIFY 
sector (clears the SMART support bits) but does not adjust the checksum 
accordingly.

Another method to hide SMART feature set would be through DCO. But the 
checksum should be correct then.

Driver bug?

Does the *-hardened kernel version probably modify or restrict I/O 
controls ?
