Can I reinstall the Apple Hardware Test?

Question

Can I reinstall the Apple Hardware Test?

After an OS reinstall, with a Macintosh HD erase, I've lost the ability to run the Apple Hardware Test directly from my drive.

Now when I try to run it, it only does so from Internet Recovery Mode, which does not sit right by me, once it used to do so without requiring an internet connection and no official Apple article, specifically, warns you that any OS reinstall process can lead to this situation (at least none that I have discovered...)

Is there any way I can get back that feature, which I presume would be installed in a Recovery partition?

MacBook Pro, OS X Mountain Lion (10.8.3)

If your Mac didn't come with DVDs, you can't get Apple Hardware Test in your hard disk anymore because it's only possible to get it starting your computer in this mode without being able to download it in OS X and copying it to a folder.

With Mountain Lion the Apple Hardware Test now runs from Internet Recovery Mode. If you still have the original discs that came with the computer you can try running it from Disc 1. But once you chose to install Mountain Lion over your original system, then you lost the ability to run the AHT from the computer. I assure you this information has been around since 2008.

My Macbook Pro is a Mid 2012 model, bought in December of that same year - it came with ML installed.

Before the process that I described above, I ran the AHT from the HD and not from Internet Recovery...

So, the assumption that AHT doesn't come packed in computers with ML installed, if true, doesn't apply to my Mac...

I can't see any relevant information, for my particular case, in the link you provided...

What am I missing?

I was actually responding to your statement "I've lost the ability to run the Apple Hardware Test directly from my drive." and provided the link (see the Use Apple Hardware Test section) so that you can make sure you were performing the test correctly.

Sorry, that the Article was of no help to you.
