PackDev Patch document 1.0
			==========================

Introduction
------------

PackDev 1.9 is an excellent and versatile disk-archiving program. It is
available from Aminet, as util/arc/PackDev1_9.lha

PackDev can be used to archive any volume, including floppy disks, MO disks and
so on. However, there is a bug in version 1.9.


The Bug
-------
Some original disks of mine have an invalid bitmap. These disks have been
write-protected from the day I bought them, and I am not about to write-enable
them to be validated.

It is not possible to determine which blocks are used for an invalidated disk.
Using the ALL keyword it *should* be possible to read all blocks. However,
because of the bug this is not possible.


The Solution
------------
The solution to this problem is to make a copy of your PackDev 1.9 executable
and apply a simple patch. Use the patched executable for reading invalidated
disks.
