(kernel 5.13, Debian/sid)
I recently installed a PCI SATA adapter: 06:00.0 SATA controller: Marvell Technology Group Ltd. 88SE9215 PCIe 2.0 x1 4-port SATA 6 Gb/s Controller (rev 11) (prog-if 01 [AHCI 1.0]) Subsystem: Marvell Technology Group Ltd. 88SE9215 PCIe 2.0 x1 4-port SATA 6 Gb/s Controller Flags: bus master, fast devsel, latency 0, IRQ 146 I/O ports at c050 [size=8] I/O ports at c040 [size=4] I/O ports at c030 [size=8] I/O ports at c020 [size=4] I/O ports at c000 [size=32] Memory at df540000 (32-bit, non-prefetchable) [size=2K] Expansion ROM at df500000 [disabled] [size=256K] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [70] Express Legacy Endpoint, MSI 00 Capabilities: [e0] SATA HBA v0.0 Capabilities: [100] Advanced Error Reporting Kernel driver in use: ahci
and now disks attached via these sata ports show up as "Removable".
In 2016 (kernel 4.4) this was introduced and some fix was done in git commit dc8b4afc4a04fac8ee55a19b59f2356a25e7e778 Author: Manuel Lauss <manuel.lauss@gmail.com> Date: Sat Feb 27 16:10:05 2016 +0100
ata: ahci: don't mark HotPlugCapable Ports as external/removable

I also miss the possibility to disable hotplug in the SATA extension card, so I see now all connected devices as removable devices in DE.
Is this to be expected? Is there a way around this?
