I recently backed up some personal files on DVD+R using Lite-On Drive and Sonic RecordNow. Now when I load the DVD+R disc in the drive it acts like a blank disc even though its obvious that data has been written on the disc. Any answers on how to get my data off the disc???
You can try IsoPuzzle (free), CDRoller, or IsoBuster (both trial ware).
IsoPuzzle has a nice feature where you can use different optical drives on other computers (which might be better readers), and add the collected data back to the recovered image on your own machine.
