I just upgraded my system from 6.1 powerpack to the new 7.0 version, and
now I can't access my cdrom. When trying to mount it I get a
"/dev/cdrom: Input/output error".
here is the recent output of dmesg...

I added a link to dev/cdrom using the command as suggested in a cdrom
howto.
ln -sf /dev/sr0 /dev/cdrom
and here is a copy of my fstab;
/dev/hda1 /mnt/nt ntfs exec,dev,suid,ro,noauto 1 1
/dev/hda2 /mnt/nt-d ntfs exec,dev,suid,ro,noauto 1 1
/dev/hda5 / ext2 defaults 1 1
/dev/hda6 /usr ext2 defaults 1 2
/dev/hda7 swap_upgrade swap defaults 0 0

/dev/cdrom /mnt/cdrom auto user,exec,dev,suid,rw 0 0
/dev/sda4 /mnt/zip auto user,exec,dev,suid,rw,uid=500 1 1
This was after I fixed the entries for zip, cdrom, and floppy, the
install had messed these up, and I
have gotten my zip to work again, but I can't seem to get the cdrom to
work.
Any Ideas??
