Fried HDD Recovery

hello everyone :) , i need some help with my fried harddrive.

I just got done putting together a custom build with 1tb hdd and 128 ssd, i was going to transfer all my important documents, pics, software, etc that were saved on my old hp that was getting replaced, which had a 500gb hitachi. After spending a few hours organizing the files on the hdd, i was finally ready to transfer it all to my new pc via my cm 690 ii advanced's x dock at the top. i hooked it up, fired up the pc and was greated by a pop and a burning smell, only to discover my hdd was fried.

After inspecting the x dock, me and my dad discovered that the 4 pin power cable that hooked up to the case's front panel where the x dock is located. Had the little pins inside in the wrong order which wern't lining up with the correct colors on the 4 pin on my powersupply. This most likely happened when we were sleaving the cables. We believe that due to them not be aligned to much voltage might of been applied to the Hdd.

Now i have read of different forms to try to recover lost data of a fried hdd, but the problem is that when ever the fried hdd is installed on the hp the comp will not power on. (will power on when its not installed)
And for fear of something happening to my new pc, i dare not try to see if it will do the same thing on my custom build.

Any advice on how bad the hdd might be fried? there doesnt appear to be any physical signs other then a little black square which seems to have exploded or melted. and does anyone know of a work around for the shutting of problem or a different way to recover the data other then going to a specialist?

Thank you to everyone! greatly appreciate it!

P.S. the data is not priceless but it is super important, the file that i was going to back up was 130gb folder, which was a mix of softare, documents, Pictures, and videos.

Try installing the hdd to a different computer.

its no good. the circuit board is fried. unless u make them, u can't probably repair them. so ur best bet is purchasing an identical drive, replace the circuit board and it should be ok. has been done before, but you NEED IDENTICAL MODEL NUMBER replacement otherwise its probably not going to work.

by circuit board do you mean the little board at the top of the hdd where the sata and power connectors are located?

yep, that green lookin thing screwed into the underside. undo the screws, carefully lift up and detach ribbon cables, there might be 2 or more.

nice, thats what me and my dad were thinking of doing. we were about to order a recertified identical hdd of the egg. when he came up with the idea that there might be a piece of metal, stuck to the circuit in the place were this little black square blew up, that was causing a short. so we inspected it, noticed there was a little piece of aluminum melted to it, removed it, and it worked 100%.

Good to know replacing the board also works, incase the little blown square causes some issues. Thank you.

The shorted component was probably a 5V TVS (transient voltage suppression) diode. For continued overvoltage protection, you can replace it with an SMAJ5.0A available from Farnell, Mouser, Digikey.

Replacing the board usually doesn't work. This is because modern hard drives have unique drive specific information stored in an EEPROM chip. This chip, or its contents, usually need to be transferred from patient to donor.
