| 2190.1 | Always more questions | WAYLAY::GORDON | Resident Lightning Designer | Fri Jan 31 1997 11:25 | 10 |
| Are the VMS versions of the source (original disk) and where the CD
mount was attempted different. As I recall, SECURITY.SYS was introduced
around V6.0 and I have vague memories of problems around the transition but
it's been a while.
Image Backup should certainly work. Did they do an ANALYZE/DISK/REPAIR
of the partition before the burn?

Created in ALPHA 6.2. Did not work in the reader. Tried to read
it on another ALPHA 6.2, same error.
DId not do the analyze/disk/repair prior to the burn, but the partition
was still out there and we ran it. Other than the usual whining about
quota.sys it ran without error.
Any other ideas?

| 2190.3 | How about... | DAVIDF::FOX | David B. Fox -- DTN 285-2091 | Mon Feb 03 1997 08:23 | 11 |
| Did you try explicitly mounting the CD /NOWRITE? I realize that VMS does that
by default on CD's but since you're having trouble mounting it, force it to be
read-only and then see what happens.
Also, was the source disk mounted SYSTEM? If so, SECURITY.SYS might have
changed or an in-memory buffer might not have been written to it. Can you mount
it privately, do the backup again, and burn again?
I'm grasping but maybe a couple of possibilities.

| 2190.4 | Let's see how many problems there are... | WAYLAY::GORDON | Resident Lightning Designer | Mon Feb 03 1997 09:52 | 13 |
| Mount both the partition and the CD /FOREIGN and use DIFF (or CMS DIFF
is better if they have CMS installed) and see it the bit patterns are the same
on both (You probably want some non-default switches on DIFF and direct the
output to a file.) If they're not, the something happened during the record.
What brand of CD-R media? Which InfoServer model? Which recorder?
Are there any apparent scratches on the CD?
Have they tried a second record? If not, don't ask them to yet, but
that's going to be a possibility down the road. After all, might just have
been a media glitch.

Doug:
Diff was not effective, as they re-wrote the partition and the CD in an
attempt to resolve the problem.
CDR media is 3M CDR 650/74
CDR is : Sony CDU920S
Infoserver 1000 (publisher)
3.4
The CD looks burnt!
The original source disk is mounted /system, and cannot be dismounted
to try this privately, as the disk is constantly in use. Even if
we re-burn and diff the CD, the cannot divulge the contents of the diff
cause then they would have to kill us... <haha) its a very classified
site.
The partition is around 500MB and the data is around 250-300MB.

| 2190.6 | You did give me a suggestion | WAYLAY::GORDON | Resident Lightning Designer | Thu Feb 06 1997 12:45 | 11 |
| They wouldn't have to kill us - I don't need to see the diffs, just
know if they're different or not.
I do have a clue though from what you said. Was the original source
disk in use when they did the image backup to the partition? Did they use
/IGNORE=INTERLOCK? Essentially, if they want to insure a usable image backup,
the backup process needs exclusive access to the device. This is a VMS
restriction and is true for image backup to any medium. It has nothing to
do with InfoServer and CD-R.
