mechanical hd pcb board replacement

[nofroyo]

Recently I put in a usb3 card and i believe i put in the molex cable incorrectly i know right what a noob, and in the process i killed a flash drive and an external drive...wtf right haha. 

the flash drive is no biggie, but the my external has some data i need and its not backed up, i know how can you not backup your data right!!! i know lesson learned. now the drive wont turn on, spin or anything,

 

prior to this was working just fine no issue. the PCB has a slight burnt smell, so i unscrewed it and discovered i burnt a chip or something on the pcb board. so my question realistically if i find an exact pcb board match is there any chance the drive will turn back on and or be able to recover my data?

 

i searched ebay and some other sites and the board is from anywhere $50.00 to $85.00 depending on the seller. 

 

BTW its a 2TB external 2.5 drive ST2000LM003

Your best hope is a data recovery service. You normally can't just swap a board and need to swap the rom chip aswell.

First off, sorry to hear that you're having trouble with your drive. It's actually not a good idea to try and replace internal HDD components yourself because HDDs are highly sensitive to dust and other particles in the air when exposed, they need to be opened in highly filtered environments known as Clean Rooms which are usually in professional data recovery businesses. The platters coming into contact with dust particles may obliterate any chance of recovering your data safely.
