1. hard drive recovery/pcb question

Was working on my pc, which has mirrored 250gb drives. PC Locked up and heard light clicking. This had happened once before, it was the power cable loose on the sata drives. I touched the cable, pc remained locked…. seemed like it powered up for a sec but nothing happened.
Powered off pc, both drives unrecognized by system. Which is odd for a mirror, but it must have gotten a power surge. One of the mirrored drives clicks on boot (not clack-clack-clack like a crashed head) but more like spin up, click, spin up, click… like it can’t find where to start. the other drive gets no power at all.
Have done PCB replacement before with success and so decided to try again. Took pcb off drive that would not power up, moved to drive that clicked. Now the "clicking" drive would not power up. that means pcb is broke/burnt.. likely both are in that case..
moved pcb from "clicking" drive to the drive that wouldn’t power up. it clicked once, and i pulled power from the system.. likely that pcb dead then too.
The mirror worked not 15 seconds before the clicking began. It would be odd for both drives in a mirror to have simultaneous head crashes… so i’m thinking it’s the pcb.
Questions:
i have 2 new drives coming in from Western Digital.. could take a PCB off one of those and see if it works… if not would need data recovery.
the pcb obviously supplies a power source. can a busted pcb make a drive click? i would THINK so, but hey, maybe not..
has anyone done data recovery like this? used a place and had good results, and not as expensive as someone like OnTrack?

2. I had, for a while, collected PCBs off drives that had mechanically failed (bad sectors, head crash, etc) thinking that one day I would need one of them to recover someone’s data off a drive where the PCB had outright failed (typically no power). It served me well a couple of times but I stopped doing it some time ago however and left them in a drawer. I am moving shortly and wanted to know if anyone was interested in them. I don’t plan on typing in all of the model numbers. They range from 10GB-200GB and are a mix of WD, Maxtor, Segate, Fujitsu, IBM and Samsung. All are IDE. I also have two complete WD 500 GB SATA drives that have failed and are out of warranty: WD5000AAVS-00ZTB0 Green Power, WD5000AAJS-32TKA0.
If anyone is interested they can have the whole lot for $30 plus actual shipping cost. I simply prefer to have them put to good use if possible otherwise I will have to take them to the local electronics dump.

3. I searched with the search function, I read the FAQ, I used google to the best of my ability and I still can’t find ANYWHERE.
Can someone, ANYONE, tell me where I can buy a replacement hard drive logic board for my Maxtor 6Y080P0? I’m going nuts over here. I have a perfectly good drive that only has a bad logic board on it and you guys know my pain… that’s 80GB that I just don’t want to throw away.
Maybe it’s just because my first hard drive was 202MB(yes I know that’s big compared to some older people) but I don’t want to just throw it away! So if you could help me out and SOMEONE provide me with a link to where I can get said equipment from I’d appreciate it.
