     586=== On OSX smartctl prints `ATA_READ_LOG_EXT (addr=0x11:0x00, page=0, n=1) failed: 48-bit ATA commands not implemented` ===
     587
     588When I run {{{smartctl -x}}} output contains lines that:
     589
     590{{{
     591ATA_READ_LOG_EXT (addr=0x11:0x00, page=0, n=1) failed: 48-bit ATA commands not implemented
     592Read SATA Phy Event Counters failed
     593}}}
     594
     595This is because OSX provides very limited SMART API and direct disk access is not allowed. It is possible to use Linux LiveCD to get full information about the drive.

     598=== OSX - External USB / !FireWire drive diagnostics support  ===
     599
     600Mac OS X does not support diagnosing external drives using S.M.A.R.T. technology “out of the box” . In order to allow your Mac to diagnose external drives, you will need to install a special third party driver. Please note that this is a requirement of Mac OS X, and not smartmontools. Links:
