Ouch, yes, please, never assume I've tested unless I say so explicitly.

So far I've just seen the expected, with one rewritable and one
read-only disc, in a pair of USB and PATAPI drives:

$ sudo plscsi /dev/scd0 /dev/hdd
export PLSCSI=/dev/scd0       // B Iomega   RRD              DB76
export PLSCSI=/dev/hdd        // @ Iomega   RRD              74.B
$
$ sudo blockdev --getro /dev/scd0 /dev/hdd
0
0
$
$ sudo dd of=/dev/scd0 bs=64K seek=0 count=1 if=/dev/zero
dd: opening `/dev/scd0': Read-only file system
$ sudo dd of=/dev/hdd bs=64K seek=0 count=1 if=/dev/zero
1+0 records in
1+0 records out
$
$ # swap discs
$
$ sudo dd of=/dev/scd0 bs=64K seek=0 count=1 if=/dev/zero
1+0 records in
1+0 records out
$ sudo dd of=/dev/hdd bs=64K seek=0 count=1 if=/dev/zero
dd: opening `/dev/hdd': Read-only file system
$

Excellent, I conclude I have understood correctly.

I trust you will tell me if I can help further.
