I was mounting some cd when i had to confront this error:

root@comarez joeri # mount /dev/cdroms/cdrom1 /mnt/cdwriter/
/dev/cdroms/cdrom1: Input/output error
mount: block device /dev/cdroms/cdrom1 is write-protected, mounting read-only
/dev/cdroms/cdrom1: Input/output error
mount: you must specify the filesystem type
root@comarez joeri #

I really does not make any sense to me. First it turns an i/o error then claiming it has been mounted ro. Yet another i/o error ending with mount telling me to specify the fs.

here's fstab:

/dev/hda1 /boot ext2 noauto,noatime $
/dev/hda3 / ext3 noatime $
/dev/hda2 none swap sw $
/dev/hdb1 /mnt/data vfat users,umask=0, $
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro $
/dev/cdroms/cdrom1 /mnt/cdwriter iso9660 noauto $

If anybody could tell me where i should be looking to solve this?

thx for ur replies.

Use the -t flag to specify that you want to use the ISO9660 file system (this option supports extensions such as MS Joliet too): mount -t iso9660 /dev/cdroms/cdrom1 /mnt/cdwriter

You cannot mount unwritten media (unburned CDRs) and you can't mount audio CD's - neither of those use the ISO9660 file system! In short, you will need a readable data CD in the device (nope, you can't mount a CD-ROM without a disc in it either).

what exactly are you trying to do? if you are trying to burn a cd, then you need cd burning software... if you are trying to mount a cd you know should have data on it, remove the disc from the drive and check for scratches, perhaps the cd is too badly damaged to be usable
