Just grab all of them (with same board) you see on ebay.
Don't do the "freezer trick" if you value your data.

A have a Maxtor 20GB 2B020H1 which is doing the spin-up then spin-down
thing. The controller says ATHENA ATA2-PLUS, FBII 301430100.

I found this site http://www.hddtech.co.uk/MaxtorFailureSymptoms.htm
and my symptoms match precisely. So I bought a working 2B020H1 used.

I swapped the contoller but the drive isn't recognized at POST. I
swapped the controller back to the spare-parts drive and that one
works fine. Worth noting is that with the spare controller, the
original drive no longer spins down after spin up.
