7.3.3S.M.A.R.T. commands

S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive moni- tors 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-5 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4H) that elimi- nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at: http://seatools.seagate.com.

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.

Table 8:	S.M.A.R.T. commands

D0H		S.M.A.R.T. Read Data
D2H		S.M.A.R.T. Enable/Disable Attribute Autosave
D3H		S.M.A.R.T. Save Attribute Values
D4H		S.M.A.R.T. Execute Off-line Immediate (runs DST)
D5H		S.M.A.R.T. Read Log Sector
D6H		S.M.A.R.T. Write Log Sector
D8H		S.M.A.R.T. Enable Operations
D9H		S.M.A.R.T. Disable Operations
DAH		S.M.A.R.T. Return Status

Note. If an appropriate code is not written to the Features Register, the command is aborted and 0x04 (abort) is written to the Error register.
