[SOLVED] IDE HD that has received “reversed” volta

I have a external hard disk case that i bought a new power adapter for. In all my eagerness i forgot to check if the 5 and 12 volt output were in the correct plugs.

The far right and the far left were switched.
So without knowing that, i fried the harddrive.
My friend allready told me that i should wave goodbye to it and i remember googling it a few months back and the only possibility of rescuing the disk was to find a similar recycled/thrown out disk, removing the fried chip from it and soldering it carefully onto the “injured” hard disk.
It’s not so much the hard drive, it was a 250 GB IDE (no one will buy these anymore, not even for 6-7 € here in Denmark) but mostly the principle or the pointless mission to make it work again. Anyone with experience on this ?
Answer #1
I don’t know about soldering the chip..First you have to know which chip..And it will take a pro to remove and solder a chip with over 150 tiny legs..
The method I know is to find a similar Model and swap the circuit board..No hard to do..Just require the correct tool..
Answer #2
Thank you for your help Your method seems a lot more practical. Yeah, i’m looking at the tiny legs now, it would require me too buy a new soldering tool, stop all caffeine ingestion and a pillow to scream into after 2 minutes of “soldering”.
It’s gonna be hard to find a similar circuit board for this old drive for free (i can buy a new one for 40 USD but it would be absurd).
By tool, do you mean the torx screw driver ?
Answer #3
It’s not possible removing the chip using a soldering iron..It requires a device that heats all around the solder and pull the chip out..
Ebay is a good place to find old stuff..
Yea..torx screw drive more likely..As most drive use non standard screws prevent you from opening them..
Answer #4
I’ll look at ebay, thank you for your help
