How to replace the hard drive from a My Book

I have a similar question. The hard drive of the WD MyBook Essential 500GB is died (not a WD fault, it’s user error, if you understand :slight_smile: ). Can I put a new hard drive into it? Of course, the MyBook Essential does have only one disk, no raid, etc. Or, can I use larger disk? For example a 2TB disk, instead of the original 500GB?
