text: 1. try to write on a lower speed\n2. Sometimes dvd-rw don't have a large enough buffer to hold data and on buffer memory down the error occurs, so you have to let the comp just to write the disk and close other apps\n3. I could be because of the files you want to write, they could be corrupted or, I don't know,  they do not have the proper access property\n(4). Clean disk may occur when the inserted cd is clean and you try to write(continue) a multisession disk.\n(5). Sometimes there are incopatibilityes of drive with the cd/dvd - my LG didn't wanted to write properly a sony cd-rw\n Good luck!
