I have connected a hard drive to my TP Link router to use as a shared data storage, however this doesn't seem to work properly.

In the management interface, it shows it as a connected USB Disk, but with 0GB size.

In the USB Storage dialog, it doesn't show at all.

The Disk is a total of 4TB, I tried it formatted as NTFS and FAT32, and also split it into smaller volumes in case the router OS couldn't handle drives of this size, but nothing made a difference here.

I found a thread discussing a very similar issue for a different router here: https://community.tp-link.com/en/home/forum/topic/227202

However the solution here seems to have been a firmware update, and I am already on the most current firmware version that is officially available.
