This directory contains a crc listing for disks 129-145 in my library,
generated directly from my current master disks. The crc file for disk
142 could not be produced because it consistently caused the crc program
to guru. Each listing was generated with a sequence of commands of the
form:
rls >ram:d001.files -q df0:
crc <ram:d001.files >ram:d001.crc -g
crc <ram:d001.crc -v
The last command is simply a check to make sure that the crc list
can be used to validate the disk contents.
These lists can tell you a lot about the state of your copy of
the library disks, but NOT whether or not you have an exact
duplicate of the library disk master. In particular:
(1) This mechanism only validates the file contents.
Generally this is what you are most interested in.
(2) It will not detect files which have been added
to a disk by a third party (and hence are not on
my master disks).
(3) It will not detect that a disk is infected with
a bootblock virus.
If you regularly distribute large numbers of my disks to third
parties, and one of your disks fails the CRC checks, you should
probably arrange to acquire a "good" copy. To ensure that only
valid copies are passed on, the disks should remain write protected
at all times.
