Hi folks.

I've been given a CD-ROM (disk), which I can't seem to read with
DR-DOS. I get an "I/O error reading drive F:" message, yet under
Linux and W95, using the same hardware, I can read this silly
CD-ROM without problems.

On one PC, with a 6 speed NEC drive, I have DR-DOS 6.0 and
have tried both MSCDEX and NWCDEX. Both give that I/O error.
Rebooting in Linux 2.4 (Mandrake 8.0), the CD-ROM reads fine.

On another PC, with a 40 speed Pine drive, I have DR-DOS 7.02+
with NWCDEX. This combination gives the above error. Rebooting
in Windoze 95SR2, again the CD-ROM reads fine. "Shutting down
to M$-DOS" (MSCDEX loaded via AUTOEXEC.BAT), I can access
the CD-ROM without error, although it shows no files, due to LFN
issues (I think).

So, why do I get these I/O errors under DR-DOS if I try to access
this particular CD-ROM, yet not Linux or W95, using the same
hardware? Is there some fix for this (eg. some special "driver")?

BTW, I'm told the CD-ROM was "burnt" on a Windoze 2000
system using some software called "Ahead Nero" (never heard
of it, but then I'm not familiar with CD-ROM burning, anyway).

TIA,
Joe.
