Here I have corrected one mistake that I made in previous post.
Also, I have tried your suggestion and the results (checksums) still do
not match. In the process of the "dd" commands I am also getting:
acd0: READ_BIG - ILLEGAL REQUEST asc=0x64 ascq=0x00 error=0x00
this happens in either of the two "dd" commands used here.

Actually, the results from the "dd" command was a result of a pasting
faux pas on my part,
i.e., it should have been:
# dd if=/dev/acd0c of=/usr/home/rclark/dup.iso bs=2048
dd: /dev/acd0c: Input/output error
94609+0 records in
94609+0 records out
193759232 bytes transferred in 126.003480 secs (1537729 bytes/sec)
However, I did as you suggested:

MOST RECENT RUN THROUGH:
-----------------------
# rm dup.iso
# dd if=/dev/racd0a of=/usr/home/rclark/dup.iso bs=2048
dd: /dev/racd0a: Input/output error
94609+0 records in
94609+0 records out
193759232 bytes transferred in 126.659459 secs (1529765 bytes/sec)
# md5 4.7-RC1-mini.iso
MD5 (4.7-RC1-mini.iso) = f154f318622bddccd245d5b5e1af314a
# md5 dup.iso
MD5 (dup.iso) = 93511ace0a9e84eec1c9b76de79a53dc
#
Note: During the above process I re-started the process from the
beginning: burning same iso to clean cd media etc. Using your
suggestion the md5 checksums still do not match.
Thanks,
Rob
