I appreciate the suggestion but that seems to not be the problem. I opened etc/fstab and here are the two lines that relate to the CDROM drives:
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0
/dev/scd1 /media/cdrom1 udf,iso9660 user,noauto 0 0
The error message I get is "wrong fs type, bad option, bad superblock on /dev/scd0, missing codepage or other error"
When I enter "dmesg | tail" I get:
[ 41.292244] eth0: no IPv6 routers present
[ 48.578826] NTFS-fs warning (device sdb1): parse_options(): Option utf8 is no longer supported, using option nls=utf8. Please use option nls=utf8 in the future and make sure utf8 is compiled either as a module or into the kernel.
[ 48.631984] NTFS volume version 3.1
[ 48l653769] NTFS-fs warning (device sdc1): parse_options(): Option utf8 is no longer supported, using option nls=utf8. Please use option nls=utf8 in the future and make sure utf8 is compiled either as a module or into the kernel.
As a result, this raw beginner is still completely stumped. All of the above is Greek to me and I have no idea what to do to get my cdrom drives to work. I load a disk and get the error message "Cannot mount volume. Invalid mount option when attempting to mount the volume 'UDF Volume'." All I do is load the disk into the drive and then close the drive. It fails to read the disk and returns the error message.
