Hi, I don't know if you can help me.
I have a 1TB WD hard drive WD10spzx.
One day it stopped working properly, I think it was because I moved the laptop roughly. At first, it detected it without any problem, but it wouldn't let me access the content, and I managed to run HDD Regenerator to see if it could be fixed. Since it's a 1TB drive, it took a long time, and I'm not sure if the connector or the PCB in general was affected by having it on for so many days in an external USB adapter while HDD Regenerator was running. Right now, I can't do anything with it. In Windows, when I try to initialize it, I get an I/O error, and in Linux, I can see it but with 0 bytes. I have another hard drive exactly the same, but I've read that if I change the PCB, I need to swap the BIOS, and that's where I get lost. I'm not an expert in hard drives, but I'll apply any solution you give me. I've read about BIOS dumps, etc.

thanks in advance

It's not a PCB fault. Running HDD Regenerator was pointless. In fact, it appears to have killed your drive. You should have cloned it with HDDSuperClone when you had the chance. Now it's too late.

I appreciate your response, I take note for future problems.
Is there nothing I can try?
I just want to recover photos of my dog, it seems silly but for me it has a lot of value.

Thank you
