Sandisk Extreme 64GB Stuck on Optimize for Performance

When I first got my drive I reformatted to NTFS and switched from Optimize for Quick Removal to Optimize for Performance. I would like to switch back but when I try to change the policy I get an error: “windows could not change the write-caching setting for the device”. I am using Windows 7. Any help would be great on what I need to do to get back to Optimize for Quick Removal.
