No Access to External Drive - Authenticated Users Gone

I deleted AUTHENTICATED USERS from my external backup drive's properties and now I can't access it even though I had full control as administrator.

When I right-click properties for the device now the SECURITY tab has gone. I only have general/tools/hardware/sharing/readyboost/customise tabs.

Any help would be appreciated.
