DVD-RAM?!?!?!?

I installed Ubuntu Gutsy. I correctly read my DVD_RAM but I cannot write
it in packet-writing mode (drag & drop). It is mounted read-only.

Suggestions?

Thanks a lot.

Remount it read/write then! :p

Presuming that the device for your DVD-RAM is */dev/sr0* and the mountpoint
is */mnt/dvd* - check your */etc/fstab* and/or */etc/mtab* for the correct
device if you're not sure - issue a command such as the following...:

sudo "mount -o remount,rw /dev/sr0 /mnt/dvd

For future use, you may want to edit */etc/fstab* and replace the /ro/
by /rw/ in the record for that device.

I would also strongly recommend the following reading - in a console window:

man mount

... and...

man fstab

UNIX is not user-unfriendly. It just expects the user to be a little more
computer-friendly. <grin>

Which filing system do you use on the DVD-RAM? The ISO system used for
-RW and -R is "read only" and cannot be mounted R/W. There is a UDF
filing system which is intended for DVD-RAMs and packet writing, but I
cannot recommend the Linux implementation. It does strange things when
overwriting existing files. Something like ext3 with noatime works fine,
though.

So long,

Actually, ISO9660 is append-only. You can't mount it rw, but you can
append additional stuff to an existing CD using appropriate mkisofs and
cdrecord options (or growisofs -M for DVDs.) In general, you wouldn't
use ISO9660 on a DVD-RAM medium.

Interesting, I hadn't heard of that. Then again, 4G isn't as much data
as it used to be, so I tend to save things until I have that much data
and just burn a single-session DVD+R.
