Internal HDD unexpectedly unmounts..HELP

Hey Gang,

I have a Mid 2009 MacBook Pro 13" with a 250HDD and a Intel SSD in an optibay. I boot off of the SSD and it works fine and has been for the last year and change.

Recently however, the original HDD does not mount, actually it will mount and then I get a popup stating that the harddrive was ejected and to eject properly. Mind you, MacBook never been dropped or mishandled. I figured maybe the HDD died, so I bought a new one, a 320GB WD, 16M cache and 7200rpm.

That mounted well and everything was fine....for about an hour and then THAT unmounted as well. When I rebooted (hard boot) it came back. When I tried with the 250, that didnt work.

I'm thinking it is the HDD cable that is bad but no clue. Do logic board go bad after a short time? I mean I have a Mac Cube with the original 20GB hard drive from 2000 and that is still working...

Any ideas?

Thanks

Had to get a new HDD ribbon from iFixIt for $40. Seems to have fixed the problem.
