I bought 851S, upgraded it to GS0F (from GS08). I have a dell desktop, WindowsXP Home. I have two problems:
When I burn an ISO image with Sonic software, after burn process Windows reports that there is no disc in the drive. Media type Verbatim x4 +RW. Afterwards I can erase the media. When I use DVDDecrypter to burn the same ISO image on the same DVD, I have no problem.
BookType change seems not to work. I set it using the tool provided by Lite-on, burned an ISO image using DVDDecrypter on Verbatim DVD+RW and on TDK DVD+R, then I checked type using the tool provided by Lite-on and kprobe. Both report DVD+R(W).
I don’t know if I should return the drive as faulty.
