Now I can't mount them. e2fsck shows no problems. I also can dd them to a file, then mount the file. But I want to be able to simply access them directly. Current system: RH 7.1 with all updates. Sorry, I can't remember the exact command I used to create the images. I also want to better understand the output of dumpe2fs, and how to relate this to mount. I will be very grateful for any help that increases my understanding of what is going on. $ sudo mount -t ext2 /dev/scd0 /cdrom -o ro mount: wrong fs type, bad option, bad superblock on /dev/scd0, or too many mounted file systems Other symptoms: $ sudo fdisk -l /dev/scd0 Note: sector size is 2048 (not 512) Disk /dev/scd0: 0 heads, 0 sectors, 0 cylinders Units = cylinders of 1 * 2048 bytes Disk /dev/scd0 doesn't contain a valid partition table $ e2fsck -v -n /dev/scd0 2>&1 | tee e2fsck-v-n-dev-scd0 e2fsck 1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09 /dev/scd0 has gone too long without being checked, check forced.
