i burnt a dvd with alcohol 120% on a Verbatim DVD-RW, the burn process appears to close the session and change the DVD-RW to DVD-ROM! The disk was unreadable in the DVD-player and unreadable in my computer.
I could not reformat it with alcohol or nero, kept getting error in CDB field!
I contacted the DVD-RW dealer who suggested that a UDF format was needed because I burned an ISO larger than 2GB. That worked and I could read the DVD-RW again.
But! the disk failed when I tried to copy a Video_TS folder to it. It is now unreadable again and unformattable! its a coaster.
So yeah it seems closing the session changes the booktype when burning an ISO with alcohol. I wish I could some how resurrect this DVD-RW! :sad:
