according to the documentation you're citing there's no need for the
format and a simple overwrite is sufficient.
I took it to mean that I can simply run the growisofs command on a
dvd-rw that has been previously recorded
and it would do the rest, but
it refuses to do this claiming
that the disk is not empty or some similar error.
Would you know what actual argument combimation does work, or whether
'overwrite' means using some other tool?
OK, I'll make it easier to understand, since you did not quote my reply from
it, I will;
If you want to nullify the media, e.g. for privacy
reasons, do it explicitly with 'growisofs -Z /dev/scdN=/dev/zero'
(remember seeing this??)
My DVD burner is /dev/hdc so as an example;
$ growisofs -Z /dev/hdc=/dev/zero
WARNING: /dev/hdc already carries isofs!
About to execute 'builtin_dd if=/dev/zero of=/dev/hdc obs=32k seek=0'

Actually takes about 25 minutes on my laptop system, I then can write a new
data session to the DVD+RW media (can do the same with DVD-RW media but I
only have DVD+RW available).
Notice I used the actual device (/dev/hdc) in the growisofs command instead
of the sym linked /dev/cdrom;
$ ls -l /dev/cdrom
lrwxrwxrwx 1 root root 3 Feb 22 09:40 /dev/cdrom -> hdc
You might want to check that your burning DVD media rpm packages for RHEL3
are current;
cdrecord-2.01.0.a32-0.EL3.2.i386.rpm 25-May-2005 10:44 467K
dvd+rw-tools-5.21.4.10.8-0.EL3.2.i386.rpm 25-May-2005 10:44 81K
