Subject: FBAD58 latest version of bad sector lockout program

The latest version of FINDBAD, the program which does a
non-destructive read of a disk and then creates a dummy file to
allocate bad sectors so CP/M won't use them, is now available from
SIMTEL20:

Filename                       Type     Bytes   CRC

Directory MICRO:<CPM.DSKUTL>
FBAD58.AQM.1                   COM      25216  F3D9H
FBAD58.COM.1                   COM       2176  D033H

Here's the update author's comments on what's new in this version:

...Added the ability to keep bad blocks that were flagged in a
previous [UNUSED].BAD file.  If a block was ever flagged as bad by
this program, it is probably weak.  If on a subsequent test, it makes
it through the BIOS retries and is read successfully, I want the block
to stay in the UNUSED.BAD file.  Removed the code in LTOP which
cleared the high byte of HL after a call to SECTRN.  My BIOS (Morrow
DJDMA) sets the high bit of HL to indicate SIDE 1 of a double sided
drive.
