Running storage device self-test on OS X

How do I run a device self-test on storage devices on OS X?

I want to send the ATA-level commands to perform self-test on a device -- not the SMART tools. I ne开发者_运维知识库ed to do it from C without the use of any 3rd party or external tools.

The smartmontools package contains two utility programs (smartctl and smartd) to control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (SMART) built into most modern ATA and SCSI harddisks. In many cases, these utilities will provide advanced warning of disk degradation and failure.
