Features
The SMART ENABLE OPERATIONS command enables access to all SMART capabilities within the device.
Prior to receipt of this command attribute values are neither monitored nor saved by the device. The device
will preserve the state of SMART (either enabled or disabled) across power cycles. Once enabled, the
receipt of subsequent SMART Enable Operations commands does not affect any of the attribute values.
If the values in the Features, LBA Mid (Cylinder Low), or LBA High (Cylinder High) registers are invalid, an
Aborted command error is posted.
Upon receipt of this command from the host, the device sets BSY, enables SMART capabilities and
functions, clears BSY, and asserts INTRQ.
