I still have hope for my dead HDD. How do I bring it back to life?

The other day, in an attempt to connect an external CD drive to my iBook, I decided to rip open my LaCie.
When it came to reconnecting the HDD to the LaCie hardware, I was stupid enough to do this with the power flowing. I was also stupid enough to try and connect the molex the wrong way round. A few sparks and a terrible odour later, I plugged the LaCie into the iBook. ...Not a whimper from the LaCie.
I took the HDD out of the chassis and connected it directly to my PC. Still dead. I know little about HDD repair but as I can't afford to send it to a specialist, it's DIY all the way.
I assumed that the problem was with the PCB. Luckily I was able to track down a board that matched the model of my HDD: Seagate Barracuda, model: ST3250823A, p/n: 9Y7283-511, firmware: 3.03.
The new board arrived today. I swapped it for the old one, reconnected everything, and plugged it in.
It spins up fine, which is an improvement at least. But after that, nothing. It doesn't do the clicky, clicky thing and neither will it mount. I've tried other HDDs in the LaCie chassis and they work fine. I connected the seagate to my PC, it spun up but still no clicky, clicky. I assume the problem is with the board... not an exact match? But, as I said, I know very little about HDD repair and so I'm worried that the problem is worse than I expected.
The new PCB was rather pricey but as a last resort, I'm considering taking a 12w soldering iron and swapping the suspect component. (I've located the component, the crack and the smell give it away, but I'm not sure what it is. It's a small black square with two thick legs at either end. The one on the old PCB is marked: QE R524, and the new one is marked: AE GP519 -- are these resistors? Do they share the same value?)
So, where do I go from here? Is the problem with the PCB? Will I see my work again? Is no clicky, clicky a bad sign?
