Why am I receiving this error code, when trying to rename a flash drive? Broken image removed


I receive this error upon attempting to rename a flash drive. The renaming process works, but I would like to know what this error is, and why it's appearing.
Have you tried reformatting the unit to FAT using disk utility and then trying to rename? FAT is the default filesystem for most USB sticks. I had this problem, reformatted it with disk util and it started working.
