My Drive show some disc as empty and complete
same disc
In friend’s drive-incomplete.

why is that and how can i continue multi session of the dvds?


#2

For some reason, multisession is not working 100% of times in DVD media. Actually, very often it fails with the risk to loose all data.

My suggestion is to recover all data with your friend drive, and save them on your HDD…

I also suggest to not use multisession with DVDs. The best alternative to a multisession disc is an USB pendrive. You can find a 8GB pendrive at a reasonable price, it is a rewritable solution and there is no need to use multisession or other tricks :slight_smile:

Additionally, the LG drive has ancient firmware. Latest is 2.00 (see http://club.myce.com/f91/post-new-firmware-tool-announcements-here-210819/ for details)
