Recovering Inaccessible HD Space for Recovery/Boot HD

[Chocol8moo]

Hi - First time posting here. Looking for a bit of help regarding GUID partitioning as I really messed things up this time...

I installed Windows through EFI previously and had some issues when the win8 os decided to mess up my boot manager. Consequently, I deleted win8 on the OS X side through diskutil and that's where things went weird in a hurry.

I noticed that my Apple_Boot Recovery HD had a disk identifier of "disk0s4" instead of "disk0s3", which annoyed me to no ends as I'm a bit tightly-wound...

$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Untitled 1              499.4 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s4

So, i decided I should just delete it and try to re-add it somehow...

$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Untitled 1              499.4 GB   disk0s2

So, the above is my HD now. So far so good, right? Nope, I can't extend disk0s2 to absorb the unallocated 650.0 MB... It doesn't even show up in that Disk Utility program thing.

I'd really appreciate if someone would point me in the right direction to recover that 650 MB of storage and reinstal the Recovery_HD partition.

Thank you guys.
