SMART commands

SMART provides near-term failure prediction for disk drives. When SMART is enabled, the drive monitors
predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a
failure is likely, SMART makes a status report available to the host. Not all failures are predictable. SMART predictability
is limited to the attributes the drive can monitor. For more information on SMART commands and implementation,
see the Draft ATA-5 Standard.
SeaTools diagnostic software activates a built-in drive self-test (DST SMART command for D4
unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:
www.seagate.com/support/downloads/seatools/.
This drive is shipped with SMART features disabled. Users must have a recent BIOS or software package that supports
