I do not believe this to be an issue with formatting. Both Linux and Windows (64bit) see it as 2TB drive. However it is supposed to be a 3TB drive. It is in an enclosure, and I am wondering if perhaps the enclosure's controller is unable to support larger than 2TB drives? It is a WD MyBook and is not meant to be taken apart to plug in the drive directly into a PC... so before I rip it apart I thought id ask for advice here. It is a USB3.0 enclosure, I believe by the time USB3.0 came about we have resolved 32bit issues?

Under what circumstances will sda1p3 show up like that with all 0's ?
Drive's internal info states its a 3TB drive:
