Does anyone has the same problems fixed?
We are using the SCO OpenServer Enterprise Version 5.0.2 on a Standard-PC
with an Adaptec SCSI controler (7870 or 1542CP) and a Plextor SCSI CD-ROM
(PX-12CSi) or/xor a player from Toshiba (XM3801TA).
We know they are not on the HW compatibility list of SCO, but as you know
it is very
difficult to get those oldies :-).
We have no problems reading "printed" CD-ROMs e.g. the one with the
But we can't read a CD-R(ecordable) we or another one have "burned".
To fix the problem, we have tried and changed crosswise the writer HW (HP
Ricoh), the media (YAMAHA, sev. SONYs, FUJI) and the writer SW (EasyCd Pro,
cdwrite under Linux, SW from YAMAHA). We have made some investigations to
correctness of the SCSI bus termination and the functionality of the CD-ROM
(no problem reading a CD-R under Windows95 !), but we always got the same
the SCO operating system:
1) The command "cksum /dev/cd0" prints the error message
cksum: Fehler beim Lesen der Daten von /dev/cd0: E/A-Fehler (Fehler 5)
This message is in German, translated:
cksum: Error reading data from /dev/cd0: I/O-Error (Error 5)
2) Because we can mount the cdrom and traverse the directories on the CD-R,
we tried to
read the files on it. We found out that we can read (or cksum) some
files and some others
not. The error message is the same as in 1).
3) The program "custom" (we want to make some installations with the CD-Rs)
an error message like the one in 1).
We suggest the problem is in the driver of the SCO operating system which
probably can not
handle all messages from the "new" CD-ROM player while reading a CD-R !?
Please write me any solutions or hints to find out what is going wrong.
Thanks in advance,
