Deskstar 5k4000 4TB drive only shows up as 1.8TB in Disk Utility
I have an older (2nd gen?) Mac Mini (intel) that I use as a home server and backup destination. My Time Machine Volume (A 2TB WD in a newertechnology ministack v3) was almost full, so I purchased a 4TB Deskstar 5K4000 and mounted it in the ministack. Oddly, Disk Utility reports its capacity as 1.8 TB, not 4TB.
So I move this mechanism to a Mygica USB SATA Dock (only 2 months old) and lo and behold, same result.
Is there something about this mechanism, Disk Utility, or OS X 10.7 that precludes using a mechanism of this size?
