mount: /dev/cdrom: can't read superblock
when i try to mount my cdrom:
$ mount /mnt/cdrom mount: /dev/cdrom: can't read superblock $ echo $? 32 $ is my disk damaged or what? how can i do rescue the information? i will thank you a lot for any suggestion.:( |
Shouldn't that be "mount /dev/cdrom /mnt/cdrom" ? Actually, you shouldn't need the "/mnt/cdrom", as usually yuor system will already have an entry in /etc/fstab that tells it where to mount the cdrom. Also, be careful about what kind of CD is it that you are trying to mount? Mounting an audio CD will return that kind of message, but a normal data CD should mount fine.

every thing with /etc/*tab is ok.
my disk is DATA, i dont know what filesystem type, so this is one more question, how can i know the file system without mounting the disk. :). My disk did work fine without problems. But in the time it torns slow and finally, dead. Many of my disks have thit same problem. :,( thank you fouldsy |
The filesystem for a CDROM drive is iso9660. A CD created with Nero InCD or Roxio DirectCD will be UDF. Is the CD store bought or one that you have burned? Have you tried these CDs in another PC? It is possible your drive is failing.
With CDs you have burned yourself make sure they are kept out of the sunlight and in a temp controlled environment. |
Yeah, i'd check the drive itself. If it seems to be struggling spinning the CD's up and then slowly spinning down and sitting doing nothing, it sounds like it might be hardware, unless all the cd's yuo are trying are fautly. Follow michaelk's suggestions of trying manufactured cd's that aren't scratched or been exposed to extended sunlight, etc.

try:
Code:
mount -t iso9660 /dev/cdrom If this works and doesn't work the second time, as others have mentioned, check the cdrom for hardware issues. --S.A.K |
mount -t iso9660 /dev/cdrom /mnt/cdrom
is working, thank you every one, nice people. :) :) Now. when the mounting finalize, i read very slow the content and some folders fails :( why that is happening? what can i do? THANKS |
It's still going back to a possible hardware problem or corrupt CD's from the sound of it, I'm afraid. Try other CD's, or if possible, replace the CD drive and use the same command to get the CD's mounted and see if you can then browse all files + folders correctly.
