Bug#994532: Installer only gives internal hand drive install option not external USB drive

[Ross Maloney]

Package: debian-testing-amd64-netinst.iso

Hello.

I have tried to install Bullseye from both the standard 11.0.0 release
and also the daily builds of 16 and 17 of this month.  I am installing
on a MacPro 2019 using a boot image which I dd from the netinst.iso
posted images.  Everything functions normally in the non-graphical
install until the manual partitioning of the disk phase.  At this stage,
the USB drive I have connected to the MacPro is not seen.  This is the
problem.  Installation on this external drive is the aim of the
installation.

I have previously installed Bullseye sid on this hardware
configuration.  That image dated 12 October 2020 gives the
identification 5.8.0-2-amd64. This problem appears to be related to the
installer.  I have checked the hardware configuration by installing the
old October 2020 image successfully today.

Is there a reason the installer now in use only offers limitted drive
options, or is this a bug?

Regards,
