It's me again, with another weird IDE device..
The device is a Panasonic PD/CD-ROM drive. Under Windows it enumerates
as two drives, apparently LUN 0 and LUN 1. LUN 0 is a CD-ROM, and LUN 1
is the PD-RW block device.
(PD is Phase-change Dual, a rewritable optical disc format developed by
Panasonic in the 1990s, it stores 650MB on a CD-sized disc encased in a
DVD-RAM-like caddy)
Unfortunately Linux 6.12.9 (on Debian Bookworm) only detects the first
LUN, the CD drive. If a PD disk is inserted into the drive then there's
no way to read it.
It seems like the Linux ATAPI layer only supports a single LUN. Is there
a way to extend it to support the second LUN on the Panasonic drive?
Thanks,

Phil.
