In my system info, the HDD size displayed is: 1TB, although I bought a 2TB version (MED500X-2000). HDD Model: Hitachi HDS72202. I did format the drive after powering on and still using the factory installed firmware (1.2.1). Any advise why the size is displayed incorrect?
This is a bug from this firmware version. It is showing the wrong size, but formatted size is ok.
To get the proper size shown up, just upgrade to latest FW version 2.0.2 and read the release notes of that one.
You will see this bug is mentioned in the release notes.
Just read the Mede8er Beginners Guide, it will give you a good start with your new mede8er when following the setup guide in it.
