From: James Stuckey on
Hello,

I posted a few days ago about not being able to read a CD/DVD. I'm still
having the same issues.

I assumed that I could do: stuckey(a)debian:~$ mount /dev/scd0 but doing so
gives me:
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Using "mount -t iso9660 /dev/scd0 /media/cdrom0" instead I still have the
same problem.

*Checking DMESG I see:*

Replying to debian-user......

1. Take the cd (you burnt with this drive) and try to mount it using another
cdrom to see the quality of that cd.
2. Take a readonly cdrom/cdr(written from some where else) and try to use it
in this drive to see how the drive works.

Please reply to the list instead of reply to any person.

I am not sure why this is happening. But I have noticed that all cdroms are
not equal. Some disks give out read error on some drives, where as they
work on other drives. Your problem may not be related to debian/win/mac,
but it may be related to that particular cdrom drive on debian.

Compatibility of read only disks are much better across drives.
Another suggestion is that, when you write cd/dvd disks, do it at a lower
speed, at least this gives better compatibility across readers

I suppose I should use "reply to all" which puts debian-user in the CC:
field?

I'm using Taiyo Yuden discs. They're said to be of good quality. The drive
in question is an ASUS 20X DVD±R DVD Model DRW-2014L1T.
