USB Wired backwards, tried replacing board, still Toshiba 500GB HDTC705XK3A1 Won't work.

Hi,

So I recently built a new computer and use the old usb breakout pci slot thing to determine how to wire the new board (instead of the manual, cause i'm a moron)

Long story short, the wires were backwards, so when I plugged in my HD to this the power wire sent power to the ground of the HD (and the ground was now on power.)

I quickly removed it when i noticed sparks to the frame, and the hard drive would not work.

Purchased an exact replacement hard drive and swapped the new "good" board into the old drive, and this causes the light to come on and the hard drive to spin, but no luck getting it recognized.

I'm wondering if there was some sort of link between the circuit and the hard drive? It was't encrypted, and it's clear the board was fried, but i wonder if there are other issues inside the drive.

will i need to swap the platters or something?

Ordinarily I wouldn't care and take the loss of the drive as punishment for my carelessness, but this happens to have all of my photos ever, several years. Bummer 🙁

Thanks in advance

There is data called "Configuration Pages" stored on a ROM chip on the PCB. Cold swapping Toshiba PCB's has never worked.

The best (lowest risk) way is to have a data recovery professional read the CP and reprogram a new board. However if it isn't worth the money you can physically move the chip using a hot air gun, to the new PCB.

Are you able to send a picture of the PCB?

@neverstopbuilding, typically you would transfer IC602 or its contents to a replacement board. PCB suppliers such as hdd-parts.com or onepcbsolution.com include a transfer service in the price. Otherwise your local TV/AV repair shop should be able to handle it for you.

Alternatively, depending on the PCB, there may be a simple, zero-cost DIY solution. Could we see a photo of the board?
