9.0 Deviations from standard

The device conforms to the referenced specifications, with deviations described below.
The interface conforms to the Working Document of Information Technology, AT Attachment with Packet Interface
Extension (ATA/ATAPI-6) Revision 3, dated 30 October 2001, with the following deviation:
Standby Timer
Write Verify
S.M.A.R.T. Return Status
Standby timer is enabled by STANDBY command or IDLE command. The
value in the Sector Count register shall be used to determine the time
programmed into the Standby timer. If the Sector Count register is zero, the
Standby timer is automatically set to 109 minutes.
WRITE VERIFY command does not include read verification after write
operation. The function is the same as WRITE SECTORS command.
S.M.A.R.T. RETURN STATUS subcommand does not check advisory
attributes. This means that the device will not report a threshold exceeded
condition unless the prefailure attributes exceed their corresponding
thresholds. For example, a Power-On Hours Attribute never results in a
negative reliability status.
