BD is a ‚Bad Disk‘ program that replaces FBAD (FINDBAD). It writes
a [LOCKED].OUT file with blocks containing any bad sectors. The disk
can then still be used in a normal manner. Unlike FBAD it also shows
the names of any files that were affected. This universal version is
for both CP/M v.2.2 and v3.0 (often called CP/M+). 90 records, 12k.

 Note:  BD v04 works equally well on either CP/M v2.2 or v3.0.

Numerous programs exist to check disks for bad records. Several of them
are commercial programs such as BADLIM, DSKMGR and RECLAIM. A few are
free such as BD, FINDBAD (often called FBAD) and Verify.

All these programs construct a file which includes the bad records. BD
is the only free program that also shows the name of any file that has
one or more of the bad records.

BD v04 is current. I tried on earlier releases to make it work on CP/M+
as well as CP/M v2.2 but with unsatisfactory results. A friend from
Australia (Jonathan Saxton) became interested in the program. He is the
sharpest person I know with regard to CP/M+. He was able to finish up
the program for satisfactory use with CP/M+. BD04 now works automatic-
ally with CP/M v2.2 or v3.0 either one. Read the BD.HLP file to see what
features the programs offers and how to interpret the information it
supplies.

This program is a „must have“ utility that any CP/M user should keep on
his master disk. It is not only more versatile than FINDBAD (or FBAD),
but somewhat faster, as well.

 HINT:  Rename to BD.COM when placing on your master disk.
