[SOLVED] Trouble with new USB

[Alex]

EDIT:  Can you plug in the USB, open Thunar file manager and look to see if it shows up under "/mnt"?  If yes, see if you can save something to it.

Yes it shows up under /mnt:

Can you open GParted and do Device -> Create Partition Table -> "msdos"; then make a new FAT32 partition that covers whole disk?

Yes:



But it still does not work. 

I have researched the problem online a bit and it seems that problems between Lexar USBs and Linux are not uncommon, but i do not think that is the problem here as the USB worked untill I fiddled with it - I feel that I somehow removed the part of it that tells any (it now wont even work with Windows - I tried it on my daughter's computer - it does not even 'see' it!) computer how to store data on the USB (is that the USB 'booting' software?).

I think that I should be doing something like is described in this article:

But I can hardly understand 1/2 of what he is talking about! LOL
