Can I recover my video after a disc error?

[Linda1957]

I have a Hitachi Camcorder that uses the mini dvd discs........on finalizing one of them I got an error message (901). I would like to know if there is any way I can get this disc to finish finalizing so I don't lose the irreplaceable footage I had on it. Also, I was wondering if anyone has an error code list for these discs. By the way, the discs I used were Memorex........and I had a few other problems with error codes on them, but I was able to recover those. Thanks in advance to anyone who may have information to let me know if there's anything I can do.
