This program can be used to issue a REASSIGN BLOCKS command to a
direct-access SCSI device, such as a disk, to map out a bad block.

The comment header from the top of the source file is appended below
for reference.  See it for usage, how to build, etc.

This program is provided in the hope that it will be useful, and provide
and example of how to use NetBSD's SCIOCCOMMAND ioctl, which provides
a mechanism for user-level processes to send raw SCSI commands to a
device.

The author of this program is Jason R. Thorpe.  He may be contacted
by sending e-mail to thorpej@NetBSD.ORG.

/*
 * sdremap <dev> <blkno> - tell a SCSI disk to remap the bad block
 *                         specified on the command line.
 *
 * Compile this on your favorite NetBSD 1.1 system with:
 *
 *	cc -I/sys -DOLD_SCSI_BYTES -o sdremap sdremap.c
 *
 * or on newer NetBSD systems with:
 *
 *	cc -I/sys -o sdremap sdremap.c
 *
 * It will be pretty obvious if you need to add or remove the OLD_SCSI_BYTES
 * define; this program won't compile if the setting is incorrect.
 *
 * When you use this program, make sure the disk you're mucking with
 * has no mounted filesystems (unless that's just not possible, in which
 * case, make sure they're mounted read-only, and you're in single-user
 * mode).  You must use the "raw partition" of the disk.  On an i386, this
 * is `d', and everywhere else `c'.
 *
 * I.e.:
 *	./sdremap /dev/rsd1d 356642

 *	Handle multiple blocks with a single command.  I'm just lazy.
