I have recently bought a new 64GB Lexar USB with the long model name of LJDV10-64G-000-106, and I am having issues partitioning it. I am able to mount, read and write to the USB without any issues but whenever I try to partition it with GParted it doesn't show up in the dropdown. Also while using the command sudo fdisk -l I receive the error fdisk: unable to seek on /dev/sdc: Invalid argument. This is a brand new USB so I am not sure why I am having these issues, especially since the device is functioning perfectly with read/write.
I have tried reformatting it on a windows machine but that does not seem to do anything.
For those who want a visual my USB looks almost exactly like

But 64GB rather than 8GB
Edit: I have just ran GParted from the terminal and I am getting a similar error, but it may give more information on the issue.
Could not determine physical sector size for /dev/sdc.
Using the logical sector size (512).
Invalid argument during seek for read on /dev/sdc
Also clearing my USB with /dev/zero fails with the the message
$ sudo dd if=/dev/zero of=/dev/sdc bs=1M
dd: writing `/dev/sdc': No space left on device
