Subject: Problems with SIG/M and CPMUG files

We are finding an alarmingly large number of files in the SIG/M and
CPMUG set on the SIMTEL20 have CRCs which do not match the documented
values.  This was NOT caused by MODEM, but by flakey disk drives used
for an intermediate disk-to-disk copy step.  Those drives were suspect
for some time, and have now been pulled for alignment.
(Unfortunately, the CRCs were checked against the "bad" disk instead
of the original or the documentation files.)

I fear that we may have to re-upload the entire set of 151 disks as
well as the 60 new ones that I'm in the process of converting to
5-1/4" N* format for upload.

While we sort this all out, we ask you to double-check the CRCs of any
files you may have FTP'd from either MICRO:<SIGM.*> or MICRO:<CPMUG.*>
against those listed in the CRC lists in their respective volumes
before using those files.

We are extremely sorry for this inconvenience.
