Macbook Pro Not Booting.

Please help. I am having a very strange issue.
About a day ago I was using my macbook pro (mid 2010 13 inch) and it suddenly just started to not respond and I was forced to switch of my mac using the power button. When I tried to boot, it got stuck on the apple logo and I also tried safe boot which was taking too long (so I was forced to switch it off again_. Now, all of a sudden , When I press the option key, 'Macintosh' not longer shows as a boot option however 'Windows/bootcamp' and "Recovery' show.
When I boot up of my external hard drive with Lion installed, I can no longer see the Macintosh partition of the hard drive and in disk utility it shows the Macintosh partition - blacked out and 'unmounted'.
Wanted to boot using Apple Hardware Test, but can't find my copy of it and not sure whether I could download a copy or not. However I do have a copy of Lion that is bootable.
I have even tried replacing the hard drive with about 5 other 2.5 inch hard drives and each time I am unable to erase and partition the hard drive in disk utlility when I try to install Lion. When I click erase or partition it says unmounting and then it stays like that indefinitely.
Not sure what to do. Is it possible to get the mac to boot again and get the data OR resin tall on another HDD. Any help would be much appreciated?
Thanks so much in advance. Sorry if my post is too informative. Just wanted to include all the details
