Disk utility crash whilst creating new partition - OSX 10.8.2

Question

Hi all,
On my MBA I tried to partition the hard disk - creating two equally sized ones from the existing 112GB.
Only 40GB are used at the moment. First Disk Utility only let me create a new one with 50 GB, but I went ahead anyway (constantly complaining that the target disk is too small....)
Disk Utility crashed in the middle of resizing and now I have a big mess - looks like it worked in resizing the primary but I can't access the 'new' half.
This is the diskutil list output:
diskutil list
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *121.3 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_CoreStorage 120.5 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: Apple_HFS Macintosh HD *52.4 GB disk1
Any idea how to access the missing part?
It's OS X 10.8.2 on MBA 5,1
Thanks a lot,

Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Then move these files to the Desktop...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.sidebarlists.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.
