naming problem

i recently purchased a cruzer blade 4GB, and when i tried to re-name the disk from “removable disk” to my cellphone number the name didn’t change.

the previous cruzer blade i had didn’t have any problems with this, any ideas what changed?

Hi. Where did you try to rename this, My Computer? And is there any error message? 

Cellphone number… clever.

Did you use dashes in the name?  Max length is 11 characters if I’m not mistaken.
