i use cdrdao 1.1.5 and get the same problem after every writing: the cd-rw isn't blankable anymore. i didn't get any errors while writing but neither cdrdao nor cdrecord is able to blank the disk afterwards. i tried it with --force, but its not possible to delete the stuff cdrdao put on it. i've killed several cd-rw's this way (most were virginal) and tested it with two recorders (ricoh mp7200 and a sanyo). i have no problems with writing to cd-rw's with cdrecord on both burners and can blank the cds afterwards (not the ones cdrdao has written on of course). i also tried writing with generic-mmc instead of generic-mmc-raw but the result was the same: a killed cd-rw :( now i've heard that ricoh drives dont make an OPC if you don't force it and are therefore susceptible to rw-problems. does cdrdao force OPC? could this be part of the problem? any help would be appreciated Patrick |

Cdrdao does a forced OPC but I think if a drive does not perform an OPC automatically it will also not perform an OPC if you ask for it (the OPC command is optional and not mandatory). Anyway, the OPC should not be related to destroying CD-RWs. In fact a writing software should not be able to destroy a CD-RW; only the recorder's firmware is able to do that. Even if cdrdao was sending a faulty command to the recorder it should not make a CD-RW unusable. Here are some questions that come to my mind: Did you get an error while writing the CD-RW? What error do you get when blanking the CD-RW? Did you try full and minimal blanking? Did you write in DAO mode with cdrecord?
