From disks I am trying to delete a partition from my USB stick. I am getting this error:

Error deleting partition /dev/sdc1: Command-line `parted --script "/dev/sdc" "rm 1"' exited with non-zero exit status 1: Error: Invalid partition table - recursive partition on /dev/sdc.

 (udisks-error-quark, 0)

Trying to format gives this error instead:

Error synchronizing after initial wipe: Timed out waiting for object (udisks-error-quark, 0)

How do I get rid of this partition so I can put a plain FAT32 one instead?
