macbook pro 13 mid 2010 hard drive cable flashing white

Hooked it back to my pc and deleted the partitions again but still nothing. Again the Mac would not recognize it in disk utility or the installer. It was formatted as a single FAT32 partition. Next I reinstalled the original 160GB drive that came with the laptop. Connected it to my PC and deleted the partitions with EaseUS partition manager, reinstalled the drive, and got the same error. Couldn't erase anything or delete the existing partitions. I tried to boot to my ML usb drive and install a clean copy of ML but kept getting errors that the drive was locked. Just the spinning white loading symbol for hours. I threw that in just to see if it would boot the existing operating system. The first was a 750GB that I pulled from my daughters 2012 Macbook pro last summer. I have since tried two different drives in the Mac.

All the data is still intact and I am able to read and write from the drive. Thinking the drive may have died, I pulled it and hooked it up to my PC via an external USB adapter. Booting from a Mountain Lion bootable usb drive I created with Lion Diskmaker 2.0.2 I found that the drive was not even showing up in the system. I had replaced the original 160GB hard drive with a Samsung 830 256MB SSD last summer.

A couple of days later, I powered it on only to find the flashing folder with a question mark.

I was using it at home a couple weeks ago and when finished I powered it down and carried it back up stairs.
