I would like to locate a good disc diag for the CCS Double Dens
Controller or find a good diag (one that does a life test) that work
through BIOS rather than the hard coded disk i/o. Any help in finding
this asap would be appreciated.C70:info-cpm (08/01/82)

If you would like to have a program to test diskettes, there is
one called FINDBAD (version 5.4 is the latest). It reads every
sector and when it finds a bad one, it adds that CP/M "group"
to a table of group numbers which is put into a dummy file at
the conclusion of the run. The program does not write to the disk,
only reads. By creating the dummy file, it causes CP/M to think
those groups are "in use", this "locking out" the bad sectors.
This public-domain program has been around for quite awhile,
works on CP/M 1.4 or 2.2 (does version number test and then reads
the disk parameter block to determine physical characteristics of
the disks). It works great on hard disks too.
The file is available from MIT-MC as AR20:CPM;FNDBAD 54ASM.
