Secure USB blocking internal Disk Drives

Hi,

I am running Build Version:10.0.532 on site

I am having some issues with Secure USB blocking internal drives. reading what that does i read it that it will block Disk drives that are USB

"Disk Drives will block/unblock USB Drives, External Hard Disks and Virtual Drives. Exercise caution while blocking the disk drives of Servers to ensure that the Virtual Drives of Servers are not blocked. Use Exclude Devices to exclude specific drives from being blocked."

I have created a policy that blocks usb drives and selected some memory sticks i still want to work that i can sign out.

The issue i am now facing is that this seems to block disk drives on computers that have more than one disk drive.

I don't really want to look at going down the route of excluding the second drives as there would be over 100 computers to check and get the device ID.

Is there any way i can make this block USBs but not block the internal drives as the policies wording suggests?

Thank you

Rich
