Help PLEASE my macbooks hd keeps unmounting making it unresponsive when I try to start up!! I went to disk Utility in recovery mode. This happens with 2 different hard drives.


I was having trouble with it previously and was told it might be the graphics card Apple techs could not confirm after testing - but I don’t think that issue would do this so I’m thinking it might be related to the other troubles.
 
Could you tell us a little more about the specific system you have? For example, mid-2012 Unibody 13-inch. In some cases, such issues can be caused by a problem with the SATA cable, and certain model MBPs are specifically known for issues with them (but not all MBPs have SATA cables because not all of them use SATA drives.)

MacBook Pro (15-inch, Late 2011)
2.2 GHz Intel Core i7
4 GB 1333 MHz DDR3
Intel HD Graphics 3000 384 MB

Also I have the original HD and a SSD and this happens with both

Also before I replaced the HD I was getting the white screen it would go to the apple logo then boot to white so I would have to do the recovery mode to get it to do anything other than white (also that recovery wouldn't work all the time) which is why people originally thought it was the GPU issue known to my computer model. But Im thinking and hoping thats not the case because this HD shouldn't unmount because of a GPU issue.. i don't think anyway lol
 
OP:

Pay attention to what Zap said in post 2 above.

It -might- be the internal ribbon cable that connects the drive to the motherboard.
When this cable goes bad, it looks to the user as if the drive has failed.
But it's NOT the drive -- it's only the cable.

The fact that BOTH your HDD and SSD won't communicate with the motherboard also seems to point to the cable.

If you replaced the HDD with the SSD yourself, then you already are familiar with getting into the back of the MacBook. It's only a small step more to replace the ribbon cable.
Go to ifixit.com to see what's involved.
They also have the part number.
You can buy the replacement cable from them or get it from ebay or online.

Since the cable is pretty cheap, I'd try replacing it first.
