Re: bad144 - how useful still? Because it's annoyingly ubiquitous.

bad144 is not used by NetBSD/vax.  

Well, that???s . . . awkward :-)

The executable may not be built, but don't the drivers (or the disklabel
code -- yow!!) still respect the bad sector lists?  The most likely use
I can see for STD 144 handling in the kernel is if one needs to read a
disk, or even a disk image, which has sectors reallocated using this
mechanism.

The individual drivers have to consult the table, and .. precious few of them actually do.

A middle ground between effectively putting this back into the individual
drivers whence it came and ripping it out totally might be to add a utility
that reads the remapping data, and then constructs a disk image that doesn't
need it.

The responsibility is already on individual drivers.
