dvd+rw-format -blank /dev/hdc
on other disks works fine and I can write multiple times (which is what I wanted as I am using the disks for backups).
Is there any way I can recover the disk? Or am I stuck with a hole in my back up set :o|
Surely it is possible to just force a write to the disk without checking what format it currently holds (maybe this is a naive view of how it works though).
Cheers

Reading the dvd-rw page though (http://fy.chalmers.se/~appro/linux/DVD+RW/-RW/) I thought I liked the sound of Restricted Overwrite mode so I ran the command
dvd+rw-format /dev/hdc
The format apparently went fine with no errors. However no when I try to write anything to the disk I get
Executing 'mkisofs -r -J stuff.mp3 | builtin_dd of=/dev/hdc obs=32k seek=0' :-( track is formatted for fixed packet size
This reminds me very much case with SONY unit [equipped with earlier firmware] and Princo media, which is indirectly mentioned on -RW page as following: "... [poor media support by unit firmware manifests itself] in bizarre ways... DVD-RW media might [reportedly] perform as write-once or maybe twice or three times... [etc]."

^^^^^^^^^^^^^^^^^^^^^^ After dvd+rw-format you should have observed "DVD-RW Restricted Overwrite" here. And the fact that you've observed ":-( track is formatted for fixed packet size" error message means that formatted procedure succeeded in some degree, because "Restricted Overwrite" does *imply* fixed packet size. So media appears to be screwed up in bizarre way....

... therefore I would strongly recommed to try another media brand before drawing final conclusions. There also it a possibility that it was media defect on that particular disc. Did you try one or several discs? A.
