If it happenned to you, it will happen to others and, if you came here ... so will some of them.
I ALWAYS *very* much do appreciate hearing of the actual, final, proper solution. A small percentage of folks ever return to the forum to report. Too bad. sometimes it is because they felt stupid what was really wrong ... most of the time, they are just on to whatever is next.
I would even like to know what bios settings, or SATA connector, or firmware setting (or update), etc., will finally make the system behave as advertised, desired, and expected.
I, for one, will file this in my knowledge base and, hopefully, I will be able to "key" on it, when I observe similar symptoms.
If you find out soon ... give us a holler !
