Can't access my EXISTING OSX 10.8.1 Recovery Partition
This computer is a non-retina mid-2012 MacBook Pro.
Using DiskUtil in Terminal shows the correct disk configuration:
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *750.2 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 749.3 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
However, booting up with Cmd-R just goes to the Internet Recovery, and booting up with Option Key shows 2 identical Macintosh HD icons - selecting either one boots the system regularly from the Macintosh HD; no Recovery Partition shows up. I had two eligible computers and the first one was updated directly from the App Store; this one was done with a bootable USB drive.
35 years into the "microcomputer revolution" I really hope that someone can suggest a solution other than "reinstall the operating system." Not that I don't appreciate help, but this should be fixable with a less drastic solution. The parition is there, something needs to be told to recognize it. Also, I don't know that reinstalling will produce any different results, although reinstalling directly from the App Store might "turn on" whatever is "turned off."
Thank you.
MacBook Pro, OS X Mountain Lion (10.8.1)
