Mounting a CD-RW

mvendramini · 08-08-2003, 08:49 PM

Hello there.

I'm having trouble trying to mount a CD-RW on my LG cd-rw recorder.
On my /etc/fstab I have:

/dev/cdrom /mnt/cdrom iso9660

And the error output reported by mount is:

mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)

I can successfuly mount and use any other CD-R, and the recorder itself works pretty well on win98. What's wrong?

Is the CD-RW blank?

Is the CD-RW defective?

Is the CD-RW recorded in some format other than iso9660?

Some older CD machines are CD-R and will neither read nor write CD-RW which has different optical qualities than either a CD or CD-R.

I'm quite sure the issue is related to the Linux configuration. The CD-RW works (say read/write) on win98 (using that easy CD creator thing).

When I tried to mount it, it was not blanked, and I tested the session under windoze.

Please help!

when you say this:

Code:

/dev/cdrom /mnt/cdrom iso9660

are you actually saying that this is all thats in the fstab for this device? or did you just not put the rest of the stuff in your post?

Do you mean a DirectCD formated CD? Those CD's are not an iso9660 format. The filesystem is called udf and that is why you get the wrong fs etc message. You can try to mount as such

mount -t udf /dev/cdrom /mnt/cdrom

If you get an error that udf is an unsupported filesystem then you will have to recompile the kernel.

Nope, it''s not formatted with DirectCD, it's an ordinary CD-RW created as "Data CD".

And yes, I've cut off the rest of the entry for the cdrom, as well as for the other devices.

mount also produces this error message, should it be important:

mount: block device /dev/cdrom is write-protected, mounting read-only

well thats not an error message, as its a cd and they are read-only....yes you can write to a cdrw but not for the case being you are mounting the cd, its not like you can go an drag and drop or copy files over to the cd as its mounted , so thats a message you will see when mounting any cd..

Well, ok...

Thanks for the info but, what about the real problem?
