Under what circumstances ?  I have TWICE had to rescue SCSI discs
that would not remap bad sectors on read.  The last time was only
a year ago, and I clearly remember the scenario:

	VREPAIR.NLM (netware's version of fsck) refused to fix the disc
	because it was reading a bad sector in the file allocation area.
	When the adaptec verifier was run, it allowed the remapping to
	be done, resulting in a good sector with bad (inconsistent) data,
	which VREPAIR was then happy to overwrite with data from a
	redundant copy.

I don't know enough about SCSI to comment on what should happen or
what behaviour one can configure from the various configuration
pages on the drive, but I can certainly say that the adaptec BIOS
has rescued me once.  So I'll always keep a 1542 somewhere around
just in case. :-)
