Re write-protect, personally I know only of discs that have write-protect tabs. Are we saying some SCSI drives have write-protect switches also? Only tape drives or also the disk drives of sd and the disc drives of cdrom/ sr/ ide-cd? Are we saying for some reason that we prefer detecting the write-protect of such a drive once at plug in rather than again after each disc insertion? For what reason? Pat LaVarre
