RE: HDD Question

so motor noise trashes electronics power line

Do you have any evidence that it's any worse than a 12-volt line esp as a 3.5" drive is so much noisier in any case?

Always provided it's big enough, I'd go for a 2.5" spinner with its own PSU. Ideally, build yourself a little linear supply but, if you can't, there are many "good-enough" devices (linear or SM) to be had. A 5-volt only PSU is (obviously) cheaper to buy and/or easier to make than a 12- and 5-volt one.

That said, I'm not clear on your setup. Assuming your old HDD was a 3.5" drive in a self-powered, USB-interfaced case, there's every chance that its PSU is fine even if the drive has died. At least as a temporary fix, you should be able to fit a 2.5" drive into the box and use the old PSU. That the small drive doesn't use the 12-volt line shouldn't matter.
