Q: Disk Utility Creating Wrong Partition Sizes

Pretty straightforward problem.

 

1. Partition a 4TB disk into 2TB/1TB/1TB

 

2. Get totally screwed up partition sizes:

What is going on, and how do I create the partition sizes that I want?

10.11.1 all software updated to latest.

Thanks!

A:

It appears I have solved the issue; Here's the rest of my journey for anyone else who may have this issue:

 

Starting from the above screen shot:

 

Tried to re-partition the existing partitions into a single 4TB

Failed with error:

 

Erased main drive, yielded a 4TB partition. Partition map showed a non-removable 0kb "Untitled" partition.

 

Proceeded to partition as 2/1/1TB (Note the odd-looking graph)

 

The "Untitled" partition is gone, and Disk Utility shows the partitions correctly on the graph, but is missing a partition on the list.

 

Quitting/Restarting Disk Utility now shows the previously missing partition. All seems well from this point.

Seems like buggy native software from Apple; Sad to see... I will report back if something goes wrong.
