Cannot access usb drive -- you do not have permission error
 

My ubuntu system on my hard disk has problems with gparted...

So I booted from a usb in order to use gparted to shrink a partition on it (formatted as ext4)

The exact error is:
You do not have the permissions necessary to view the contents of “37e11092-192f-4e1a-bde0-2ac5ea808028”.

Here are some specs. Please help.

What are the exact steps taken that lead to this error? It's not clear why you would need to "view contents of ...8028", which your df output shows is a (USB) device (because it is unpartitioned) with EXT4 filesystem.

Note that partitioning utilities of all types normally require superuser permission, so either sudo or root login to run them.

Exact steps:

1. Boot with usb
2. Plug in second usb that I want to work on
3. Immediately I get the error:

You do not have the permissions necessary to view the contents of “37e11092-192f-4e1a-bde0-2ac5ea808028”.

Exactly what does this entail? What do you see on the screen right before you plug in the other stick? We can't reproduce what you did if we don't know what you did. Most people don't boot from a USB stick to use a partitioner on another stick.

I'm just going to start from scratch. I thought there might be a simple way to get permission. Thanks for your help.
