Subject: Bad sector lockout program

MC:CPM;FINDBD ASM is the source code for the latest version of
"FINDBAD", a program which runs under CP/M 1.4 or 2.x.  It
attempts to read all sectors on your disk (non-destructive
test) and builds a table of group numbers to allocate to a
dummy file so that CP/M will not attempt to use those areas
of your disk.  It's great for "validating" new disks.  Sure
saves the grief of later finding out that there are a few bad
sectors on your disk and getting a BDOS ERROR message when you
end that two-hour edit session!  This program was originally
published in "Interface Age", but has undergone many significant
improvements since its publication.
