Retrieving data from old DVD with open session
0
Given that my current Easy HDD Recorder by PackardBell is not working anymore, I have a bunch of recorded DVDs with an open session which I cannot see on the other devices. In particular, it seems that the DVDs are in an open session that has not been closed yet.

Captcha does not let me post answers. So as comment: The first track is unwritten. No chance to read it. For track 2 try "dd if=/dev/sr1 bs=2048 skip=15888 of=dvd_track2.img" or "sudo mount -o sbsector=15888 /dev/sr1 /home/famiglia/point". (I you need more diagnosis, mail to me: scdbackup at gmx dot net)

It seems that there is no superblock in the DVD, and therefore in no way I am able to mount it. Is there a way through which I can manually/automatically create a superblock, so that the dvd_track2.img will be now visible?
– jackb
Dec 30 '18 at 16:03
Question is what kind of storage structure is on the DVD. The complaint about no superblock might mean that there is a filesystem superblock but it is not recognized by Linux. Normal UDF for DVD should be recognizable.
– Thomas Schmitt
Dec 30 '18 at 20:12
The first sectors in the DVD are not written but, other finalized DVDs that I have, are in the standard DVD video format, and therefore they should be in UDF. I sense that the DVD recorder used to writhe those sectors only when finalizing the DVD. Therefore I'm wondering if it is possible to create a superblock for the dd-ed img file.

Well, yes. But somebody would have to find out from where the recorder took the necessary info to create a chain of up to 5 UDF descriptors up to the root directory. Maybe you find some data recovery tool which can detect the files in the dd'ed image by their content. (Google: foremost.sourceforge.net ... "file carving" ... help.ubuntu.com/community/…)

Captcha does not let me post answers. So as comment: The first track is unwritten. No chance to read it. For track 2 try "dd if=/dev/sr1 bs=2048 skip=15888 of=dvd_track2.img" or "sudo mount -o sbsector=15888 /dev/sr1 /home/famiglia/point". (I you need more diagnosis, mail to me: scdbackup at gmx dot net)

It seems that there is no superblock in the DVD, and therefore in no way I am able to mount it. Is there a way through which I can manually/automatically create a superblock, so that the dvd_track2.img will be now visible?

Question is what kind of storage structure is on the DVD. The complaint about no superblock might mean that there is a filesystem superblock but it is not recognized by Linux. Normal UDF for DVD should be recognizable.

The first sectors in the DVD are not written but, other finalized DVDs that I have, are in the standard DVD video format, and therefore they should be in UDF. I sense that the DVD recorder used to writhe those sectors only when finalizing the DVD. Therefore I'm wondering if it is possible to create a superblock for the dd-ed img file.

Well, yes. But somebody would have to find out from where the recorder took the necessary info to create a chain of up to 5 UDF descriptors up to the root directory. Maybe you find some data recovery tool which can detect the files in the dd'ed image by their content. (Google: foremost.sourceforge.net ... "file carving" ... help.ubuntu.com/community/…)
