I am having slight problems burning CDRW. I get them burned without errors. When I try to mount it after burning I get an error saying it's wrong format. But if I mount an CD-R disk and after unmounting it I again mount the CDRW it's readable.
Same happens every time if the burned CDRW is mounted first. After mounting some other disk first the CDRW is readable.
The same happens if I try to read that CDRW in Windows XP too. I don't have any problems burning CDRW in Windows on the same machine.
