SCSI low-level utils

["T. Horsnell" <tsh mrc-lmb cam ac uk>]

Can anyone recommend a utility which will let me do SCSI-disk things
like surface scan, low-level format, bad-block re-vector and such?
Rather like the scu utility on my Alpha box.
smartctl cant do this stuff, and I've so far located Joerg Schilling's
sformat-3.4 (which was last modified in 1998 and which currently wont
compile on my Opteron box) and the Seagate 'seatools' utility (which
doesnt offer low-level bad-block testing/revectoring).

Any advice appreciated.

Cheers,
Terry
