Faulty DVD +RW
"In windows explorer I noticed that the faulty disk was not correctly recognized, not even showing a label. Explorer only sometimes showed (not always) that disk had full capacity available although I knew that that was not the case as I burned something to it but was not able to read it.
As I desribed earlier to my opinion the problem is caused by a damged or faulty TOC on the disc.
What I did, I decided to fire up once again good old DVDdecrypter and check out all the menus if there is a way to change and write a new label (volume name). As this should overwrite the existing content of the TOC.
It appears that this option is available. In the tools menu of DVDdecrypter under tab ISO.
Followed the popupmenu and selected an image (iso) to fill in a label name and hit ok.
Then I burned my image with DVDdecrypter to the DVD and voila succesfully completing (first it start erasing, then writing).
After that did the final check, fired up windows explorer and yes!!! the disc is recognized and readable again on the PC.
Showing the label and correct amount of bytes used. Also dir's and files are visible again in windows explorer.
Also it plays now again without a problem in Powerdvd.
So job done and one DVD+RW disc recovered for further use.
The writing of the new label apparently repaired the fault in the TOC, which caused the PC DVD drive not to recognize the disc correctly.
Hope it works for others to, who knows how many DVD+RW's have been thrown away by mistake as people thought they could not be used anymore because of formatting problem caused by faulty TOC".
I do not take credit for this, I found this solution somewhere on the net.
