The problem is detailed below.
After having formatted the USB pendrive with WinManagement, no more options appear for it.
Also, Diskpart (with admin rights) detects it only as a Volume, NOT as a Disk, also refuses many seemingly
useful commands.

(This pendrive can also be only partially detected in an other laptop, by a linux Gnome file browser, where I had no success with my beginner knowledge & some linux command line tools either.)

Thanx if help comes.

It would suggest that when you first formatted it you did not use a default, file allocation block size.
It`s odd how it says it has no volume capacity, or free space so it suggests it cannot read the current file allocation block size to what it was formatted too. the default should be 4096.

Greets Maestro Shaun o, & thanx!

Yes, something went wrong, maybe with block size.
But for sure, I forgot this step:
Create a Simple Volume

If I understand correctly, then as this tutorial says, this command would affect the selected disk (if trying it in command prompt with Diskpart), so perhaps I shouldn't try it, as the USB pedrive is not listed among drives (only among volumes).

Or could I somehow amend / repair bad reformatting? But no option seems for it...
