Aye. Ouch by now I've discard two drafts of line-by-line replies. Perhaps first I should say, yes I have studied cdrom/ ide-cd/ sr here. Jens Axboe & friends have taught me how those work in a tangle of recent linux-scsi threads now paused at "Re: [PATCH] CDC_WR". Maybe here I mean to ask: can we easily nutshell for me how well write-protect works now in sd? I understand that we find mode sense of header alone and mode sense of xFF troublesome. I'm not clear how often we try those techniques. Do we try only soon after plug in or also soon after each disc insertion? Tell me that much and maybe I can more concisely make the rest of my confusion clear. Pat LaVarre
