I have a 2007 model Macbook Pro running Yosemite 10.10.1. My father recently upgraded my hard drive for me from the stock 320GB hdd to a hybrid 500GB hdd. He's not really a Mac user and said there were some kind of issues partitioning the hard drive so right now I have 320GB of available space with 180GB of unallocated space.

I've read there are some issues with Yosemite and partitioning hard drives. I've tried expanding my partition but each time Disk Utility just ends up freezing. Should I just reinstall Yosemite entirely or what are my options? I'm at "A" school in the Navy right now and don't have access to an external drive of any kind, although I MAY be able to get my hands on one.

Here's the output of diskutil list:

/dev/disk0
#:                       TYPE NAME                    SIZE       IDENTIFIER
0:      GUID_partition_scheme                        *500.1 GB   disk0
1:         Microsoft Reserved                         134.2 MB   disk0s1
2:                        EFI EFI                     209.7 MB   disk0s2
3:                  Apple_HFS  Macintosh HD           319.2 GB   disk0s3
4:                 Apple_Boot Recovery HD             650.1 MB   disk0s4

And here is the next:

 diskutil cs list

  • Please start Terminal.app, enter 'diskutil list' and 'diskutil cs list' (each followed by 'enter'-key) and add the output to your question. – klanomath Jan 10 '15 at 15:58
  • @klanomath see above! – skarz Jan 10 '15 at 16:02
  • The partition layout is non-standard: "#1 Microsoft reserved disk0s1" is really uncommon. Please add 'sudo gpt -r -vv show disk0' and enter an admin password (the password won't be visible typing it!). Please also add the hard disk model. – klanomath Jan 10 '15 at 16:12
  • @klanomath add aboved! I appreciate your time btw. – skarz Jan 10 '15 at 16:16
  • did you already install some apps and stored some personal data on the disk or is it a fresh install? Do you have a backup and a thumb drive? – klanomath Jan 10 '15 at 16:50
