[ubuntu] caot create partition table

I have attached a picture of gparted screen showing the offending thumb drive info and other stuff. My problem seems simple. I have this thumb drive and thought to format it and then give it a new partition after deleting any others to make sure it was absolutely clean. Anyway, I formatted it and deleted partitions and then created a new partition table and then tried to add a partition. When I try and add the partition I get "No partition table found on device /dev/sdc".

I then tried to use fixparts but it could not open the mbr and failed with:
Loading MBR data from /dev/sdc/
Problem opening /dev/sdc/ for reading! Error is 20.
Unable to read MBR data from '/dev/sdc/'! Exiting!

I then tried fixdisk and got:
Unable to open file or device /dev/sdc

I have, basically, destroyed the sd card (micro), I think. Hopefully I am wrong and somebody has a fix?
