Something like that. But..

In *nix the whole disk is normally given at connection time a device
name like /dev/sda
whereas its *partitions* would be /dev/sda1, /dev/sda2 etc etc.

when its mounted under /media it may have another name.

The mount command will show what devices you have and where they are
mounted.
So with the disks attached try

mount | grep '^/dev'

To identify the device name.

E.g. when I use the above command on as USB  attached raspberry PI
bootable drive on my desktop machine I get this:

/dev/sda5 on / type ext4 (rw,relatime,errors=remount-ro)
/dev/sda1 on /boot/efi type vfat
(rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
/dev/sdb1 on /media/leo/bootfs type vfat
(rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)
/dev/sdb2 on /media/leo/rootfs type ext4
(rw,nosuid,nodev,relatime,uhelper=udisks2)

This shows that the actual PC is running off /dev/sda. but the Pi disk
has been given the name /dev/sdb

The fact that its been automounted on /media is irrelevant You can only
mount *partitions*  but you want the whole disk - in this case /dev/sdb2
