can't read DVD+RW in Sony DW-G120A immediately after growisofs
I'm now quite confused. I'm attempting to use a Sony DW-G120A DVD+-RW
which I have mounted in an external USB chassis. I have successfully
burned CD-RWs with cdrecord, but am having no luck burning a DVD+RW. I
have formatted two different DVD+RW blank and tried to record with what
appears to be no success.
I can not read the recorded DVD+RWs in a DVD-ROM drive in my laptop.
nile:509 $ cat /dev/hdc | file -
cat: /dev/hdc: No medium found
(perhaps that drive is just stupid)
I can read a commercial video DVD in the USB-attached Sony DW-G120A.
I can burn a DVD-R in the Sony, I can read that DVD-R in both the Sony
and in my laptop DVD-ROM (and play it with ogle).
I am not experienced enough to figure out what is going wrong with the
DVD+RW.
