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.

You could try 'lsblk /dev/<device>' and see what that outputs, see if that helps make sense of a) the device's partition layout and b) any filesystems on those partitions. For example:

root@fedora:~# lsblk /dev/nvme0n1
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
nvme0n1     259:0    0 953.9G  0 disk
├─nvme0n1p1 259:1    0   600M  0 part /boot/efi
├─nvme0n1p2 259:2    0     1G  0 part /boot
└─nvme0n1p3 259:3    0 952.3G  0 part /home
                                      /
And then 'lsblk -f /dev/<device>' to show what's known about filesystems:

# lsblk -f /dev/nvme0n1
NAME        FSTYPE FSVER LABEL                 UUID                                 FSAVAIL FSUSE% MOUNTPOINTS
nvme0n1                                                                                            
├─nvme0n1p1 vfat   FAT32                       DC0B-5B4B                             579.7M     3% /boot/efi
├─nvme0n1p2 ext4   1.0                         3352353a-c664-4631-aec0-82ba2ceec4bc  614.8M    30% /boot

                                                                                                   /
 I suspect if you've formatted the disk on Windows you'll have NTFS or exFAT?
