NAME
smash - rewrite bad disk sectors
SYNOPSIS
/etc/smash device sector
DESCRIPTION
Smash attempts to read the named (decimal, 512-byte) sector from the
named device, and prints the error status from the read and the data
read, in octal, regardless of the error status. It then prompts to
which there are three answers:
y Write the data back to the sector.
c Write zeros to the sector.
anything else
Quit.
After the sector is written, it is read again and the cycle repeats.
Writing the sector, even if its contents could be correctly read, will
recompute the error correcting code. This may make soft ECC errors
vanish, and will recover what can be recovered (sometimes not much)
from hard ECC errors.
