It is not mounted automatically, according to df -h.

It is neither listed in fdisk -l.

I do not notice a different number of entries in /sys/class/scsi_host/ after unplugging the SATA data cable.

Note that I notice that the connected HDD is rotating.

BIOS:

Why Hot Plug disabled by default? For security?

I switched to Enabled for all slots.

After hot plugging:

sudo fdisk -l
Output: 
Disk /dev/sda: 5,46 TiB, 6001175126016 bytes, 11721045168 sectors
Disk model: TOSHIBA HDWD260 
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

nautilus and df -h do not show anything more.

umount works as expected.
