This sounds like it is faulty:

From the SanDisk Forum:

Re: SanDisk Cruzer Blade 16GB write protected error ‎> 05-17-2012 10:55 AM

Dear All who are suffering from write protection error,

The customer service answered to me and they know about the issue, so here it is to clarify the situation to everyone:

"I understand that you are getting write protection error while accessing your Cruzer flash drive. The flash drive has detected a potential fault and has become write protected to prevent data loss. There is no method to fix this. You will need to backup your data and replace the flash drive. Our team of developers is in combination with the OS developers looking into a solution to resolve this issue. Please note that only a minor percentage of users are experiencing the write protection issue and these are the customers posting on the internet to find a solution." So wait, or change back your drive if it's under warranty...
