Can be paired with a USB Hard Drive to do many NAS things

As for NAS I have locked my self out by trying to set up the use of a hard drive on it and changed the main password by accident its a bit confusing with all its password security.

I own several of this company's servers as well and the newest one I bought keeps corrupting data, even with new hard drives installed.

I couldn't get an external hard drive to connect to it and couldn't get the VPN client to work either.
