ok. I believe you are describing a Rewritable DVD.
they do in fact have a UDF file structure
IF this is a rewritable disk the file structure would be subject to change.

Scan Disk is a tool to check for issues with a File Allocation Table (FAT)
I dont believe it works with UDF..Ive never had to look that up.

the UDF may be possible to recover/correct.
if ISOBuster cant read/repair it.. you are SOL.

UDF Reader as well as professional CD, DVD, BD and HD DVD data recovery tool !

IsoBuster is, among many other things, a perfect UDF reader. Because it is a stand-alone tool, without any drivers installed, it is a very stable way to read and copy data from the UDF file-system to your HD (or any other location). And because of the highly integrated recovery procedures it is able to cope with many physical and logical problems that prevent other UDF readers to get to your data. It's a powerful tool and only one click away from opening your UDF discs.

Imagine you insert a CD in your drive and you know you copied data to the CD via a UDF drag and drop application, but now suddenly the CD appears blank. Simply start IsoBuster and it will show you all the files and will allow you to copy (extract) these files to any other location on your PC or network.

Also, suppose some very critical pointers were destroyed by your drive or write application so that the data is "virtually" gone, then IsoBuster features the option to " Find lost UDF files and folders ". During this scan IsoBuster picks up all the files, folders and file-system remains and puzzles them all together best as possible. The track record speaks for itself.

IsoBuster recovers from, so called packet written, or drag and drop created, discs created with: Roxio Direct CD, Roxio Drag-to-Disc, Ahead / Nero InCD, Prassi / Veritas / Sonic DLA, VOB / Pinnacle Instant-Write, CeQuadrat Packet CD, NTI FileCD, BHA B's CLiP, Sony abCD, Sony Mavica, and many more ...

Last, IsoBuster is also a Mount Rainier (MRW) and (Method 2 / Method 3) remapper that automatically detects and remaps the data in the background if the CD or DVD formatting is not supported by your CD or DVD reader.
