Re: Setting booktype on BTC 100[48] drives
First of all can you confirm that this actually affects DVD-dash recordings as well? I'm not sure what you mean by your first sentence. You can set the book type for DVD-RW media to DVD-ROM. I wondered if booktype settings apply to both DVD- and DVD+, or DVD+ only. Given the dvd+rw-mediainfo output you provided, the answer is both. I just wanted to be sure, that's all. It does seem to restrict the book type depending on the current media. At least, when I try to change DVD+RW media to DVD-RW book, it gives me an error: Perfect. # scsi -f /dev/rcd1c -c 'fa 00 32 00 00 00 00 00 00 00 aa ff' Could you try scsi -f /dev/rcd1c -c 'fa 00 32 00 00 00 00 00 00 00'? As already mentioned the command seems to be 10 bytes long, 'aa ff' appears rather as dummy padding than meaningfull part of the command. I also wonder if you can try 'fa 00 32 00 01 00 00 00 00 00'? The -s 3 option sets the timeout to 3 seconds. Sometimes it takes a few seconds to return; other times it returns immediately. However, even when it does return immediately, the drive may still be writing to the media and will reject additional commands with ASC/ASCQ 04/08 (LUN not ready, long write in progress). Perfect. A.
