If you own the internal Sony DRU810A DVD writer (not the UL external drive) then there is a new firmware upgrade available. This will update the firmware from the production 1.0a to 1.0d. Apparently you can expect writing performance and reliability improvements. The firmware can be downloaded from this location: http://sony.storagesupport.com/dvdrw/dru810adwn.htm It arrives in a .zip file and the executable is contained within. Installation is painless but does require a system re-boot. I have not tried the drive since upgrading but will tomorrow and am very hopeful that it resolves this drives general weakness with DVD+DL media changing 40-50% of the following into coasters: TraxData DVD+R DL - RichoJpn D00 RiData DVD+R DL - Ritek D01 Infiniti DVD+R DL - MAG D01
Have been burning all week and have had 100% DVD+R DL successful burn rate using Infiniti MAG D01 media. After I use up all this stock I will try others....but it is certainly looking like the firmware update has done the trick.
