mounting a 16TB USB on Fedora 40

[Ranjan Maitra]

I recently got a 16TB USB disk and was trying to mount it on Fedora 40 using spacefm. I get the following:

Mount /dev/sdb:

Status: Finished with error (Exit status 1).

Object /org/freedesktop/UDisks2/block_devices/sdb is not a mountable file system.

My first instinct was that I got taken for a ride so I hopped over to a colleague's Windoze machine, but there the USB drive is visible (with the capacitty of 15.2 GiB, as expected).

So, is there anything special that I have to do to mount it on Fedora 40, because of its size?

Thank you for any suggestions, and best wishes,
Ranjan
