I have a Lenovo x220i notebook computer which came with a 320 GB HDD. A few months ago, I purchased an Intel 80 GB mSATA SSD and installed that myself. I made the SSD my boot drive and I mapped the 320 HDD as a D drive. This has worked great for the past few months until tonight, the computer just suddenly failed. The screen went black without warning. Now when I try to boot, the hard drive light flashes briefly and within 2 seconds the computer fails with no audible sound given.

Is it reasonable to guess that my mSATA SSD is what has failed me here?

No. If the drive failed, there would be a some kind of disk error displayed on the screen.
