Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

I damaged my laptop hard drive, by trying to power it in a desktop, using a sata adapter inserted in a molex with different voltages (for using a fan)
So, it received 12V instead of 5.
Today I received a new drive, and took the NVRAM (8 pin ROM) off my drive and solder it to the new PCB. After installing it to my drive, the engine starts spinning, but it sounds like it's not calibrated.
Do you have any ideas? What am I missing?

Hello,
yes
maybe your preamp is gone too. (or the ROM is different inside the MCU.)
This case require a pro help.
seek for a pro near you.

Hungary is near, can you help? Or do you know someone in Romania ?
Let me tell again what I did.
1. Powered the drive with 12V instead of 5V (tried it for about 6-7 times)
2. Took a PCB from a friend with same drive, and replaced it with no success. As a note, when I installed the PCB back to my friend's hdd, first time it didn't work. I had to clean the connectors with rubbing alcohol, then it was OK.
3. Desolder my NVRAM and solder it to good working PCB, installed the PCB with my NVRAM, again no success. (paid $40 on eBay for a new HDD to replace my friend's HDD)
Did I make it worse ?

Did I make it worse ?
Maybe no.
But there is a little chance for yes, and the data allready unrecoverable.
