Coincidentally I have noticed that the disk capacity reports in "About this Mac" and the Terminal when running
diskutil list both report inconsistent capacities for an external hard disk drive.
This is an 2TB external hard drive. However, when adding the capacities of all partitions I get a value which is significantly below:
How is this possible? Where did the remaining ~365GB go?
This disk had been formatted and used under OSX Mountain Lion.
