I'm trying to write a set of eight files to CD-R using RSJ. However,
while trying to copy the first of the eight from hard disk to CD-R, I
get a SYS0023: Data error (cyclic redundancy check), while RSJ gives
me a Reserve Track/Medium Error/CD control error (check ASCQ). But
where is the problem? If the problem is with the CD writer, then
why doesn't it happen when I write the second through eighth files
of the set (which has been done successfully)? If the problem is with
the original file, then why doesn't it happen when I copy it to another
directory or another physical disk? If the problem is with the cache
file, then why does it happen even when I use CDCOPY, which bypasses
the cache file?

Is it possible that the content of the file is somehow triggering a
false positive on the CRC? Is RSJ triggering both the SYS0023 operating
system error and the RSJ error, in which case one could suspect a bug in
the RSJ code?

I had a somewhat similar problem with A/D Creator when the image file was
on a drive that was starting to fail. I would be able to create the image
file, but when I was burning the CDR I would hit an error as it was
reading the image and the burn would abort. Are you using Dani's drivers?
If so, run diskinfo -c and see if you show errors on the drive holding the
file or the cache. If so, you might be seeing the same problem I had.

In my case I corrected this by creating the image file on another of my
drives. I also used NDFS to mount the image file and verify it as fully
readable before I burned it. You might want to try this method and see if
you encounter any problems with the image file before you burn it with
RSJ. At a minimum it will allow you to see if it is a burner problem. If
RSJ can't burn the image try using cdrecord to do the job. If neither can
do it and you don't show any disk errors I would suspect a burner or media
problem.

If you have UDF installed you could try copying the file to a UDF
formatted CDRW to see what happens.

If you have UDF installed you could try copying the file to a UDF
formatted CDRW to see what happens.
I do have UDF installed, but the only blank RW media I had available
was DVD-RW, so I formatted that as UDF (successfully) and then tried
to copy the file to the UDF drive. I first got a SYS0029 (unable to
write), after which I tried to copy a bunch of different files to the
drive, all resulting in SYS0030 (unable to read). So I removed the
DVD-RW and inserted a pressed CD to see if the device could read it
(I used PMSEEK to search for a random string of characters), at which
point OS/2 locked up.

After rebooting, suddenly I could use RSJ to write the file that had
previously caused the CRC error to a CD-R without problems, and I also
performed a routine backup to DVD+RW (I recycle my DVD+RW media after
three backups) without problems.

So apparently the system was in a weird state when I first tried the
operation. About the only aspect of its behavior that I found unusual
prior to the problem occurring was that after exiting a text editor,
the focus would jump back to some other window rather than the one from
which I launched the text editor. I've seen the same bahvior on my
office OS/2 machine. Seems to be a window-dependent phenomenon. From
some command prompts, I can launch the editor and have the focus return
to that command prompt window after I exit the editor, but one particular
command prompt window won't recapture the focus after exiting the editor.

Yep, LUSER. As in, Dickless Thollon is a LUSER.
