Recuva doesn't recognize 25 and 50 GB UDF DVDs.
Has anyone a solution for this problem?
Recuva won't/can't recover from rewritable DVD. It isn't meant for optical drives.
There are tools that can (google) but whether any tool will be able is going to depend on just how the DVD was erased.
Thank you for your help.
In the meantime I had success using Diskdigger
