SEAGATE 600 SSD PRODUCT MANUAL, REV. B 31
4.3.3 S.M.A.R.T. commands
S.M.A.R.T. provides near-term failure prediction for drives. When S.M.A.R.T. is enabled, the drive monitors predetermined
drive attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R .T.
makes a status report available to the host. Not all failures are predictable. S.M.A.R.T. predictability is limited to the attributes
the drive can monitor. For more information on S.M.A.R.T. commands and implementation, see the Draft ATA-8 Standard.
SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4
H
) that eliminates
unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:
http://www.seagate.com/support/downloads/seatools/.
This drive is shipped with S.M.A.R.T. features disabled. You must have a recent BIOS or software package that supports
S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses.
Note. If an appropriate code is not written to the Features Register, the command is aborted and 0x 04 (abort) is written
to the Error register.
4.3.4 SSD Percentage Endurance Remaining Indicator
An application can interrogate the drive through the host to determine an estimate of the percentage of device life that is
remaining. Seagate SeaTools diagnostic software has the capability to report the indicator value.
