Hi,
im trying since fews weeks to get back data if possible of my HDD.
Symptom, few alert on Windows 10 with blue screen, then few days later the disk was 100% charge and cannot access anymore with no noise from motor, nothing is recognize on bios, config pannel etc..
I have buy a PCB and now trying to check if my hard drive is respond on terminal to check the manufacturer before reprogramming my new pcb with the bios of the pcb with problem.

So today trying to dialog on putty without response i use baud rate of 38400, connect TX on DB9 to RX on HDD serial, GND to GND and TX DB9 to RX HDD.

Im sure that the prolific USB serial converter is OK i used this at work, after open the putty i power On the HDD with the power cable from my computer but there is no noise from the HDD when power On.

HDD reference is ST3000DM001 seagate, barracuda 3000GB, FW CC24.
If the firmware is failed the HDD motor will never be power On? Where i can find a firmware to try replace it on PCB (new or old)? Or if you have other answer to my problem im aware

On the firmware programmer i can read the EEPROM SPI it is a 4Mbits but i don't know the manufacturer of the EEPROM so i don't know what to read, i trying few manufacturer with the same EEPROM size if have every time different data read. I use CH341A Mini Programmer (Black Edition) to try reading the EEPROM.

Thanks,
Regards

With new PCB did the drive spin? If not, (and assuming it makes absolutely no noise), it's probably blown preamp (i.e., bad heads). In this case, the Motor Controller ("smooth") chip is probably burnt on the original PCB. If it makes faint noises when powered on, then it's probably stuck heads.

Hi, yes i try first when receveid the new pcb, the HDD has never spin.
Then i try to read eeprom of this new PCB maybe it was empty but i read only FFFF. The pcb customer said when buying you need to reprogram the flash i just confirm that.

2 things to consider:
- everything (flash, com port) runs at 1.8V,
- you will be in big trouble if you manage to kill the flash before you can read it.

In what that solve my problem to know that? You just add more question than answer.
Exemple of the flash programmer i trying to used.
https://lebonsalon.com/guide-flasher-bios-mini-programmeur-spi-ch341a/

Just move the chip to one PCB to another, but be VERY careful not to break it.

But it could be a blown fuse or a shorted TVS Diod on the original PCB preventing the drive to spin up. Can you unload pictures of both sides of the broken PCB?

The route is for you to walk it along. I told you two important things to consider. I won't hold anybody's hand, especially if i am not convinced about his/her capabilities.
It was rather a call for taking it to somebody familiar with these things if you are not sure what you are doing.
We see enough drives messed up by DIY attempts.

Old PCB:




And my new PCB:



Yes im not familliar with the HDD rescue it's my first try, but im electronician and engineer software now. I have some skills and yes i had no read that the flash component should be used by a power On max at 1.8V and my flash programmer delivered 3v3 i saw some video no one talk about that like some stupid things we can't find on internet. Maybe i will finish by solder this component and will see. I dislike CMS but it should work or not i don't care i just want try the best i can do to save some data if possible without pay an astronomic money for that.
