Question Problem with flash drive not listed in File Manager ?

[thomastt371]

I'm running Linux Q40S and when i plug in a flash drive a pop-up tells me it's mounted and it's listed in disc drives but not listed in file manager ?

What simple steps can i take to resolve this issue, ?
It only started yesterday. before that all processes were working normally.

Can anyone help ?

Does the flash drive work/appear as expected on any other systems?

It might be unformatted.

Most flash drives these days arrive formatted exFAT. Some of my really old USB memory sticks are FAT32, but I reformat some modern drives from exFAT to NTFS in Windows.
