Hmmm... Grounding..... Interesting.

It's just a good way to isolate problems.  For example, the motherboard
could be doing something strange on the 12v rail and the PSU could be
too sensitive causing the whole rail to fluctuate slightly leading to
occasional transmission errors.  SATA links are the first to be affected
by those kinds of electrical problems.

Yeah, sure.
