Summarizing
a Long story: I'm using Ubuntu 7.10 gutsy, and I've been
working/researching for almost one week on how to create a multisession
DVD+R for backing up. I've moved from growisofs to genisoimage to
wodim, finally to cdrecord cdrecord 2.01.01a37. I manually installed
cdrecord 2.01.01a37 from smake. I seem to be able to create the first
track with mkisofs and burn with cdrecord. It is mountable and
readable. But when I get ready to do the second track with cdrecord
-msinfo dev=3,0,0; it states:
cdrecord: Cannot read first writable address
----------------------------
Here is what I've done. For the first track:
mkisofs -v -o track_01.iso -R /media/sdc1/backups
Next I burn:
cdrecord -v speed=2 dev=2,0,0 -eject -multi -tao -data track_01.iso
I noticed that durning the burn:
Starting to write CD/DVD/BD at speed 4 in real SAO mode for multi
session.
I thought it was a bad DVD drive, so I switched it with another, and I
still received SAO, even though I stated -multi and -tao.
See comment below
Finally I
do my:
cdrecord -msinfo dev=3,0,0
And get:
cdrecord: Cannot read first writable address
Doing a cdrecord: cdrecord -minfo dev=3,0,0:

Note the lack of TAO here, so SAO is used instead. I assume that's
acceptable, Joerg understands these mode well enough to get it
"usefully right" here. So I don't think there's a problem with SAO.
My drives return TAO, SAO, or both, depending on model. Example:

I can mount this. I'm new to all of this, but I'm assuming it is
closing the disc. I am open to suggestions. Thanks
I think this is a clue, "block device /dev/scd0 is write-protected" may
indicate that you are running as non-root, after being root to write
the first session. In any case, it is probably related.
