Hi to all out there. I would just like to post this for all you people out there that have errors writing CD's. If u ever get an error that states...............Session fixation error, could not perform fixation. There is a way to make sure your data is not lost and also it saves alot of cd's. In my opinion it has something to do with the quality of the media thats used. Anyway to retrieve your valuable data either purchase the following software or you could download if u know where to look!! DVD X Rescue. Every disc that has caused this error I have retrieved 100% of data. The only problem I have found is the time it takes to read the info from the disc and place it on your PC, So that's a small price to pay and you can still keep things archived. Hope this helps at least 1 person out there.
