Not really, scsi(8) was flushed out at my request and expense to replace
just 1 of the tools I had to run under DOS frequently, several of the
other tools I use less often and have not sought out a FreeBSD replacement
for.

The ``tool'' I usually use for running a ``verify with remap'' pass is the
aha2940 BIOS lately, since I can just pop the drive on a test setup and
fix it.

scsiformat(8) is destructive only, I can't fix a drive full of data
with it.  :-(.  How hard would it be to extend it so that it does
what the aha2940 ``verify'' mode does?
