    DLP 9.1 - Prompted to format blocked USB Storage device



      We are in the process of testing the USB storage device blocking capabilities of DLP. I created a basic device class that contains the USB bus type and a rule to block the devices when online.

      This works fine on our Windows XP systems but there is a problem with those running Windows 7. When connecting a USB storage device to these machines we get a prompt from windows to format the device. It appears that the filesystem has been locked by DLP but Windows is still trying to mount it.

      To go a step further, if you proceed at the prompt to format, Windows can happily erase the drive. Further access to the device is still blocked by DLP.


      Any suggestions on working around this issue?
