Ouch. Where are you? Maybe one of us could simply mail you one?

That would be great!

My address is:

I have never even heard of a CD exploding, let along have it happen to
me before!

Thanks

Exploding CDs have been known to happen. Particulary in high speed
players where a disk is damaged. Dropping a CD/DVD can put a small
invisible crack in the disk and that caused the problem.

I've heard of this happening a few times - particularly when
the 56x CD players were introduced.

My concern would be the damage to the CD drive when the CD came apart.

I doublt that the disk has ever been dropped or damaged. My guess is
that it was just old and perhaps the plastic has become brittle with
age.

I have always thought that CDs were a great and inexpensive way to
archive stuff but if they disintegrate with age I may need to rethink
that! Of course even a bunch of copies may be worthless if they all
explode when you go to read them 10 years later!

The drive is pretty much toast as well. Millions of tiny pieces of
the CD are now in the drive. Even if you could remove them all it
quite possible that the exploding CD damaged the drive as well.

I really do need to find a replacement SCO 5.0.6 disk. If anyone can
mail me one I will be happy to reimburse you and put you on the top of
my "good guy" list.

I'll try to send one today. Now, if you've got some old 5.0.6 or 5.0.7
*license* or two you can sell off cheap, I've got a use for them to
set up a virtual system while some old systems stay active. It turns
out that VMware Workstation works quite well for virtualized 5.0.6, as
long as you use the IDE drive configurations and don't mess with SCSI
in the installation process.

Yeah, I'd strongly consider replacing that for any server grade
machine. As wonderful as CD's are, mechanical damage to them from mis-
handling and degradation ov their laminated surfaces from age,
especially in cheap CD-R's, makes them less robust for long-term
storage than many people realize.

I have ISO images of sco506j.iso, sco506j_supplement.iso, and one with 506
updates which could be used to burn new CDs (useless of course without
licenses).

I have been doing major digging through my file cabinets here since the
floor in my office is being replaced as all my shop area. I have found
several unused user license packages for Open Server <= 5.0.6a.

I haven't forgotten you, I've got a cleanly burned CD in my hands. But
the UK "Post Offices" close damned early, and I can't use work mail
for this.

I was able to burn a CD from a image I received from Bill who is
certainly at the top of by good guy list. Thanks Bill.

I was not able to copy a customer's disk remotely. I did a dd if=/dev/
rcd0 of=/tmp/sco5.0.6.iso but when I used this image to burn a CD
under windows it would not boot. When I used Bill's image and windows
to burn the CD it worked great. Not sure why my attempt did not
work. Anyone have any ideas? Is dd not the way to create a bootable
ISO image?

Next time someone is nice enough to copy something for you that might not _technically_ be legal to copy (from a company that just spent 4 years and all it's fortunes trying to sue everyone it could over just such technicalities no less!), thank them by having the clue to shut up about it, or at least not advertize it to the world and all of history from now on in a public, searcheable, online archive!

At least you didn't say "Bill"'s last name. Hint: DON'T

dd if=/dev/cd0 of=file.iso works fine.

/dev/rcd0 is the programming interface to the drive, where commands are sent and status is read, not where the payload data is read/written, at least not by the likes of dd.

Usually

/dev/r... is the character device
/dev/... is the block device

Sometimes the character device is needed. So your statement is not
totally correct.

I always do a sum -r on the image and the device to make sure they match.

From man sum...

-r
Use an alternate (older) algorithm to compute the
checksum. This alternate algorithm is sensitive to the
order of the bytes in the data; the standard algorithm is
not.

Good Luck,
