Hello, I'm reporting in with the same problem. I have a brand new Asus Z96J laptop with a TSSTcorp CD/DVDW TS-L632D dual-layer DVD burner and any disk I put into it and try to browse using the Explorer, I get the "prepare this blank disk" dialog. (System came with Vista Home Premium pre-installed) However, I can open up a command prompt, do "d:" and press Enter, and then do "dir" and press Enter and I can see all the files on the DVD. Is this a new Vista security feature? I have to resort to msdos copy and xcopy to read optical disks? I discovered this problem while trying to resolve a different issue: not being able to burn dual layer disks. (This right after fixing the problem with the ACPI Lid driver where my display would remain black if I closed and reopened the lid.) Finally I installed Ulead DVD MovieFactory 5 and it was able to successfully burn *AND VERIFY* a dual-layer disk with over 7Gigs of stuff burnt onto it. Imagine my surprise when I eject and reload the disk to get the message "prepare this blank disk"... fortunately I was able to verify on a separate computer that it burned successfully and the problem is related to Vista. Hope this helped someone out there -Steve.
