 I was trying to repair a sata 1tb harddrive and had a 500gb harddrive that had a circutboard on the back that looked almost exactly like it. what i did was try and switch the boards out so i could use the TB because the original board had the smaller sata plastic plugin broken off, the metal was still there but there was nothing to back it up. Anyways after replaceign them nither would power on at all. ive pluged them up inside a desktop as well as a usb harddrive adapter.

I ran into another problem, /cry when i was trying to trouble shoot the problem on the TB the screwdriver(flathead) sliped and cut 3 cords below the board. i soldered them back together and swaped the boards back to their original hdd. but still nighter will power on. Before i switched both harddrives powered on, as for my 500gb it worked perfectly but after i switched and switched back it stoped powering on. ive tried cleaning the pads that connect the board to the harddrive to no avail as for the Tb harddrives board it doent look damaged enough to not power on and the disks on both drives are intact its just the circut board and the 4 wirepards under the Tb harddrive, but i think ive repaired that much because it was just a simple electrical connection.

I would relly like some help on this. did it fry both boards by trying to swap them?
If so what parts need to be replaced on the board?(i can solder, ive modded my psp before so i have experiance in micro tech.)

O yeah, about the screwdriver incident, i was getting impatient and tried to use a screwdriver that was too small. I know that i should if used the right tool for the job but a Flathead was all i had. The Flathead size i had worked Perfectly but when i was at home and tried to use a multitools Flathead it slipped because it didn't lock in place.

perhaps check for solder splash shorting out some of the tracks, Grab a magnifying glass and give it a good inspection to see if you cut some tracks with the screwdriver

Do you have a picture of the damage?

yeah dude, I think they are broken too

did the drives have the same cache and SATA controllers on the circuit boards you swapped?(probably not)

Don't think it fried both, probably a soldering trace, if you move the original board to the drive it worked with previously, hopefully it'll work again :S

You need to swap the small eeprom between HDDs as that holds the parameters for the drives (at least with seagates you do)

Otherwise its just whirr-click whirr click when you power it up.

If you are not able to do SMD soldering then forget it.

New Development!!! for the Tb hard drive!!

I took off the back circuit board to look it over and noticed that the solder wasn't attaching properly so i picked it off and scraped some more of the film away and re soldered it properly. now the TB hard drive will spin but then stop and spin stop then once more and completely stop. I did put the same board that came with it back on it, identified by the broken sata plastic. As for the 500gb hard drive it still does the same thing, ither is spinning and i cant feel the vibration or it isn't powering on at all.

Also i managed to fix an old 40gb laptop hard drive i had from Maxtor. all i had to do on it was remove the front button and solder the power circuit together so that only the usb 2 adapter remained supplying more power to the 40gb hdd.

You could also waste a lot of time trying to fix these, that's fine if you don't value your time spare very highly I guess.
