39 | | The [https://github.com/RJVB/OS-X-SAT-SMART-Driver OS-X-SAT-SMART-Driver] provides access to SMART data for SAT capable USB and Firewire devices on Mac OS X. This works without {{{-d sat}}} option. Note that this does not support USB bridges with vendor specific commands (JMicron, Sunplus), 48-bit ATA commands ({{{-l xerror}}}) or non-SMART ATA commands ({{{-s apm,N}}}). Full USB support would require SCSI pass-through support which does not yet exist on Mac OS X. |
