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
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.
Then I noticed that the spare controller part number is slightly different. The new one reads "ATHEN II/POKER". What's interesting is why this controller would not be detected by the BIOS when attached to the old platter assembly. I verified that the geometry and the Maxtor part numbers are both the same.
Anyway, aside from trying to find another spare controller that matches exactly, and before I resort to an $800+ professional recovery, is there anything else I should try?
