Drive Formatting - Not Operational

I have a Sandisk Wireless USB Stick, that has data stored on it. Whether Arch, Debian or Ubuntu I am unable to format the unit. Firstly, I attempted gparted to attempt to format the device (/dev/sdc) however upon performing the action (and being flagged as "successful") the content of the USB remains.

When I look at blkid I get the following information:

   /dev/sdc1: SEC_TYPE="msdos" UUID="833C-CDB0" TYPE="vfat" PARTUUID="0dfab3a5-01"
   /dev/sdc2: LABEL="NEW VOLUME" UUID="523E-7BD9" TYPE="vfat" PARTUUID="0dfab3a5-02"

Further to this I attempted dd the disk to get an outcome, but I still get the above behaviour of files magically returning:

home# dd if=/dev/urandom of=/dev/sdc bs=1M

Within GNOME Disks, I see 9.2GB worth of data consumed. I am starting to suspect some issue with the USB, but wanted to see if there are any other tools Ubuntu has to offer for disk managememt/formatting.
