So, in the course of moving a hard drive from one enclosure to another I managed to let the magic smoke out.
It is in the power area but it doesn't look like the TVS diode is affected.
My questions are:
1) Am I correct that a PCB replacement is the only solution?
2) I have had difficulty finding this exact board. It is 100535537 Rev A with B5502C30 controller IC and SMOOTH 100536983 HDD Motor IC. Will any of the other 100535537 boards work as a starting point (I can mostly find the B5502C20 controller IC and SH6968B2 HDD Motor IC)?
3) I know I'll need to swap the EEPROM - which chip is it? Is it the one marked "Flash" in the HDD from inside picture or is it the one farther to the left?
4) I had flashed the BIOS on the board from CC3E to CC49 - will I be able to do the EEPROM swap and install and then flash the BIOS again, or will I have to find a board with CC49 already on it?
I have a backup so this isn't a critical operation but I thought it might be a good exercise to try to see what I could recover.
Solved! Go to Solution.

Fantastic! Even with my less-than-stellar soldering skills I was able to get a wire across the pads next to the burned out inductor, and the drive spins up and reads great! Now to get the data off it and set it aside as a spare.
You guys are great!

Exactly the same problem for me too Looks like this is more common than I thought in Seagate....
Above solution is exactly what I was searching for!!! Thanks a bunch!!
I am planning to add a UPS to my system before even soldering this wire across to wake up my dead STS31000528AS drive and get my data off it asap. Idea is to protect my other HDD's from dying like this. My Samsumg 80GB has held on for 7.5 years now without a sound.
Would adding a UPS protect from such power surges? I am still skeptical about it.

Nope, get a surge plug adapter unit like this http://www.google.co.uk/products/catalog?q=surge+p

Does that mean a UPS and an Invertor are one and the same? I do have an Invertor (and a spike gaurd as well) but the invertor was set for default wide range which does not protect PC's from rebooting.
The voltage regulator is same as a Stabilizer, if I understand correctly. Is there any good reference specs that I should look for while buying a Stabilizer?
On other thoughts, is there a possibility that my SMPS went crazy and delivered more than +5V by itself? Is there an SMPS out there which also does voltage regulation by itself? Just curious..
Thanks for the answers!!

i am pretty much having the same problem but the inductor that burnt up on mine is on pins 4 5 and 6 which i think is on the ground can i run a wire from this ground to the other ground somehow or does anyone know a way to fix this really need help added a pic not great but i think you can tell what is wrong Thanks ALOT

Did you get any replies to your problem? I am having the same problem as my hard drive got fried. The inductors leading to pins 4, 5 & 6 got charred and I don't know how to replace the inductors so I can get my hard drive to work again. If I had to solder a wire, I don't know from where exactly to solder from and exactly to where. If any one can help, that would be great.
