CD-RW compatibility


i am having a problem mounting and accessing cd-rw's burnt with nero under windoze xp. it only seems to be cd-rw's though...cd-r's that i had burnt before mount just fine. i thought maybe a bad , scratched or smudged disk but i have the same problem with brand new pristine cd-rw's. perhaps nero? is there another windoze app with better linux compatability?

the cd-rw's were burnt iso9660 / mode 1 / joliet (also tried no joliet) / no relaxed settings

i have the all the file systems compiled into my kernel and i am not using scsi emulation...2.6.6 kernel

this is my fstab:
/dev/hda3 swap swap defaults 0 0
/dev/hda1 / ext2 defaults 1 1
/dev/hda2 /home ext2 defaults 1 2
/dev/cdrom /mnt/cdrom iso9660 noauto,user,ro 0 0
/dev/cdrw /mnt/cdrw iso9660 noauto,user,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,user 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0


*note: on two occassions i COULD mount and read the cd-rw's using the exact same settings, but after erasing and burning again i got the error again...

mount: wrong fs type, bad option, bad superblock on /dev/cdrw,
or too many mounted file systems

...i also receive the error when trying to mount it on the cdrom




it is almost as if the cd-rw's are being seen as audio cd's

If it possible that the dvd is using the udf file system. This link might help.

Did you burn multi-session or leave the disc session open? I'm not sure how the filesystem would differ (if at all) in this case.

Just to see, you could try mounting as a UDF filesystem. That would be the first thing I would try.

mount -t udf /dev/cdrw /mnt/cdrw

I have had no problems with CD-RWs burnt in XP (not with nero, with roxio-style drag and drop straight to the CD folder). I have not tried it with a multi/open session disc though.

You could insert the disk while running k3b. It may provide information on the disk that will help you mount it properly.

One other idea is to install supermount. I believe it is available for slackware. Then you could mount a cd/dvd with either an iso9660 or udf filesystem.

mount -t udf /dev/cdrw /mnt/cdrw

no multi-session
finalized
disk-at-once/96


'mount -t udf /dev/cdrw /mnt/cdrw' produced the same error

when using k3b and the cd-rw disk in the cd-rw drive...the drive spins and it tries to read it and i get either could not mount device or k3b freezes

when using k3b and the cd-rw disk in the cd-rom drive...same as the cd-rw drive plus my hdd light goes steady as if the contents of the disk are being copied to the hard drive.



linux box
cd-rom: BCD - F520D CD-ROM
cd-rw: YAMAHA - CRW2200E

windows box
cd-rw: LITE-ON - LTR-48126S

okay...i just burnt it again and k3b reads it now


the only settings changes i made were:
changed write speed from 4x to 2x
changed disc-at-once/96 to disc-at-once
changed no relaxed joliet to allow joliet filenames > 64


will see if i can reproduce this successful burn later
