So I had a failing 1TB drive in my macbook pro, I managed to copy it bit for bit to a new 2TB drive. The new 2TB clone now works fine.
I have 2 partitions on the new drive, OSX yosemite and windows 7 running on bootcamp. Those 2 partitions are 599GB and 399GB respectively. So I have 1TB of free space on the new drive.
Now without going through the pain of trying to do what I'd ideally like: expand both of these partitions to fill the free space and have to make sure the MBR and GBT are in sync, I figured I'd just create a 3rd partition for OSX to use and just store large files on it.
When I run disk utility and select the free space which is below both the OSX and Bootcamp partitions I can click the little + symbol and select Mac OS Extended (journaled) then apply.
Then I get the famous error:
Partition failed with the error: The chosen size is not valid for the chosen file system.
Any ideas how to create a 3rd partition here?
to give you an idea of my setup below is the output from diskutil list in Terminal:
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *2.0 TB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS OS X 599.5 GB disk0s2
3: Microsoft Basic Data BOOTCAMP 399.9 GB disk0s3
