Bobby,
It might have taken some time, but it looks like a good result - glad I was able to help.
Simply to satisfy my curiosity (not to add you much value) can I ask you to quickly check a couple of easy things that will show how that laptop left Lenovo?
As you know, the original diagnosis was that you might have a SATAII 3Gbps controller, that would be entirely compatible, but not work to best advantage, with the SSD. (It is and was what it is, it wouldn't change any approach).
I checked further, and there was quite a bit of confusion on the web, with various opinions, but one seemingly informed person swore that it was a SATAIII 6Gbps controller, but that Lenovo were shipping them with SATAII disks.
That's fairly odd practice, but Lenovo's own specs contain the following for the storage option:
Up to 1TB [SATA II (SATA III compatible)] HDD storage - [320GB/500GB(5400rpm/7500rpm), 750GB(5400rpm)/1TB]
....which frankly doesn't help, as it can be interpreted every which way.
So, for no real reason other than being curious, if I (you) can find the answer, then I'd be grateful.
Absolutely in your own time, and don't bother if you don't want to, there's little advantage to you (except that HWINFO64 is an interesting and useful tool to have installed - for instance, we could have had an immediate second opinion on the status of your failing disk if you had had it).
It shouldn't take long, and doesn't do anything to your machine other than install the (read-only) utility.

Download and install HWINFO64 from here:
www.sac.sk/download/utildiag/hwi_642.exe
Run it and follow the procedure in this write up to determine the controller speed:
www.nextofwindows.com/how-to-tell-the-storage-controller-is-sata-2-or-sata-3-on-windows
Your system values will, of course, be different to those shown in the above.
Do go through to the end, the first bit will immediately tell you your Crucial SSD is 6Gbps capable (which we know) but that is "only one end of the pipe"....
....the later step gives the controller capability at "the other end of the pipe". I think, being Intel, your "Bus" expansion will look quite a bit like the one in the link. The names reflect the chipsets, so you probably won't see "Sandy Bridge" or "Cougar Point", (maybe Ivy Bridge) but you should find one "SATA Controller" or "SATA AHCI Controller" in there (if not, expand each of the collapsed trees under BUS 0 and look again).
We simply need the "Interface Speed Supported" result from the RH pane, as described in the link.

I'm beginning to think it will be SATA 6Gbps (which would be nice) and if it is, I'd then like to check if they really were shipping with back-level disks.
So, if you've done the above, to finish off, can you either give me the model type and numbers from the failing(ed) disk: I can check the rated speed. It might actually be easier just to dropbox a photo of the label.
I'd not be entirely surprised to find it's an IBM or Hitachi/HGST Travelstar 750GB 5400rpm SATA 3Gbps (but what do I know?)
(and if you do get here, leave HWINFO64 installed and have a play - it's read-only and doesn't break things)
