Phew, I used the trusty "wrap two folds of your shirt around either end of the connector and squeeze with plyers" technique to tighten the crimps on my cables. All three connectors looked loose, but the primary one looked worse than the pic in the FAQ.

So, I will continue to wonder how I could get a new cable or if I even need one. Oh well, at least I can stop listening to the radio that I've been subjected to for the 4 days it took to do the drive upgrade. Nano-neurosis has it's faults, I guess.
