Partition problem after HDD to SSD swap Recently decided to replace my nearly full 500GB HDD with a 1TB SSD to breathe some new life into my mid-2010 Macbook Pro. I used a toaster-style drive cloner (Dyconn Dubbler) to do a sector by sector duplication of the drive. Everything went smoothly but when I booted up from the new drive, I seem to only have around 500 GB of total space, almost all of it full. I fooled around with the partitions a little in disk utility, hoping I could maybe create and delete one, but haven't had any luck. Thought I would be able to drag the partition size but that doesn't seem to be an option. Here is what I see in disk utility with the drive attached/mounted from my other machine:



Feel like I am missing something obvious here, any help would be greatly appreciated!

Edit: forgot to mention, running most recent version of Yosemite
The following diskutil cs resizeStack command is vastly undocumented and as such potentially destructive.

Please backup your Mac OS X before proceeding.


First you have to backup your Recovery HD: Start Terminal.app and enter
defaults write com.apple.DiskUtility DUDebugMenuEnabled 1 press enter and quit Terminal.app
Start Disk Utility and enable 'Show every Partition' in the Debug menu
After a few seconds all partitions should be visible
Choose Recovery HD on the left side and mount the partition Recovery HD. If the Recovery HD is missing skip to step 7.


Verify the disk


Create a disk image of Recovery HD and save it read-only externally


Check the disk image for restore


Detach all external drives
Restart into Internet Recovery Mode by pressing altcmdR
or a bootable Mavericks or Yosemite Thumb Drive (full system or install).
start Terminal from the menubar/utilities
enter following command at the Terminal prompt: 


  diskutil cs list

Copy the Logical Volume (LV) alphanumeric UUID of your CoreStorage volume. The LVUUID should be the fourth listed.
Run the following command:  


  diskutil cs resizeStack LVUUID partsize  


According to the number found above it would be:  


  diskutil cs resizeStack xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx 100%  


This will hopefully expand your CoreStorage volume to full 1 TB. Depending on your disk this will take several seconds (SSD) or minutes (HDD). After a successful resize check with diskutil list if the  Recovery HD still exists.
Quit Terminal.app and start Disk Utility and verify the expanded volume.
Reboot to Recovery HD and your main drive. Delete the disk image created in step 5 if everything works as expected.
