So I have had the grey bar appearing and my MBP failing to boot up with the original HD it came with, Hitachi 320 GB. I took it out and replaced it with a Samsung 840 Evo SSD and still have some data I would like to take out from my original HD. I purchased a usb to HDD adapter so I can plug it in externally in hopes to clone it and back it up on to my external HD, but have had no luck. I am running out of hope and ideas of how I can get stuff off of that drive, I am thinking of going into an Apple store and see if they can help me, yeah I am that desperate at this point. I first purchased a SABRENT USB 3.0 TO SATA/IDE 2.5/3.5/5.25-INCH Hard Drive Converter but I would not see my HD, it would appear on disc utility but it would be greyed out.
