SeaTools diagnostic software activates a built-in drive self-test (DST
S.M.A.R.T. command for D4

) that eliminates unnecessary drive returns.
The diagnostic software ships with all new drives and is also available at:
www.seagate.com/support/npf/seatools/seatool-entry.shtml.
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 0
x
04 (abort) is written to the Error
register.
