Mounting and formatting DVD-RAM

I have had these (or somewhat similar errors) as well, but this is one upgrade and a fresh install ago so don't know how I solved it then. I checked some of my old links (as I only ever tested CDRW which may not be identical to DVD-RAM) and cam across this in the Gentoo WIki, which mentions (1) not to use cdwrtool (only for CDRW), but mkudffs instead. If that gives trying to change type of multiple extents it suggests not using mkudffs but dvd+rw-format /dev/hdc instead. I guess you have not yet tried to do this (especially after doing up the pktsetup thing). Just an idea..

Thanks, pindakoe. I appreciate your input. I will give it one last go, but if that doesn't work, I don't know what to do. I'm a little skeptical that it will work, but definitely will give it a go.

 

After this, the only thing left to do is to go to w.... hrmh.... to 'another place' and format it there to UDF. :blink:

Nope...

[root@localhost ~]# mkudffs /dev/sr0
   trying to change type of multiple extents
   [root@localhost ~]# mkudffs /dev/dvd
   trying to change type of multiple extents
   [root@localhost ~]# mkudffs /dev/cdrom
   trying to change type of multiple extents
   [root@localhost ~]# mkudffs --media-type=dvdram /dev/sr0
	 trying to change type of multiple extents
	 [root@localhost ~]#

 

And once again, the same I tried earlier:

[root@localhost ~]# cdrwtool -d /dev/sr0 -q
 using device /dev/sr0
 wait_cmd: Input/output error
 Command failed: 5c 00 00 00 00 00 00 00 0c 00 00 00 - sense 05.30.02
 [root@localhost ~]# cdrwtool -d /dev/dvd -q
 using device /dev/dvd
 wait_cmd: Input/output error
 Command failed: 5c 00 00 00 00 00 00 00 0c 00 00 00 - sense 05.30.02
 [root@localhost ~]# cdrwtool -d /media/cdrom -q
 using device /media/cdrom
 set_options
 can't unlock door
 [root@localhost ~]#

 

In the last try (as well as a few posts earlier) it says: "set_options | can't unlock door". What's all that?

I can't say it will help for sure, but when I had DVD problems, this page was of great help to me:

http://fy.chalmers.se/~appro/linux/DVD+RW/ (especially the Tutorial).

 

Yves.

Thanks Yves; I didn't see anything there that would give me something new.

 

It may be that I'm just too thick to figure it out... :unsure:

I haven't figured this thing out yet. What I did was format this DVD-RAM in Windoze with InCD (came with NERO 6) to different versions of udf. I thought: Hey, this will solve my problems! Alas, no...

 

I now get Mandriva to recognize the DVD - it even let's me see the contents of the DVD, but it won't let me do anything with it. In other words, I don't have any rights to the DVD - even as root.

This is what I now get in Terminal:

[root@localhost /]# umount /dev/sr0
   [root@localhost /]# mount /media/cdrom
   mount: block device /dev/sr0 is write-protected, mounting read-only
   [root@localhost /]# umount /dev/sr0
   [root@localhost /]# mount /dev/sr0
   mount: can't find /dev/sr0 in /etc/fstab or /etc/mtab
   [root@localhost /]# cdrwtool -d /dev/sr0 -q
   using device /dev/sr0
   wait_cmd: Input/output error
   Command failed: 5c 00 00 00 00 00 00 00 0c 00 00 00 - sense 05.30.02
   [root@localhost /]# mount /media/cdrom
   mount: block device /dev/sr0 is write-protected, mounting read-only
   [root@localhost /]#

Any ideas how to proceed?
