I bought a new Dell e521 a couple of months ago. I just decided to start backing up my DVDs on DL instead of compressing them. I have Verbatim DVD+R DL disks and have tried 4 times to burn DL and they all failed after about 50-60%. I have Alcohol 120% and that didn't work. I also downloaded CloneDVD and it failed as well. I have this DVD burner: TSSTCORP DVD+-RW TS-H653A D300 1009 Any ideas? Anyone know where to get the firmware update? Can't seem to find anything. Thanks.
