How to connect an external USB hard drive via Sata?

[aignn]

Hello!
I have Samsung M3 Portable disc (inside ST500LM014). Is no longer detected by the system. The display is lit, the sounds are heard inside. Normal as it was. But the system is not defined.
I read that the USB controller dies inset these disks and have heard about the possibility connect via SATA and recover the data.

Is it possible to do?
If so, you can not tell exactly where to solder? Found examples, but I can't on the Board to understand

The other side of the PCB is more interesting, at least for USB-to-SATA conversion.

However, I would start by measuring the voltages.

Hello! Thank you!
But can i connect to board like this:

It’s unlikely to be a PCB issue given that it spins up normally, but you could try a USB2 cable.

Also check for bad/broken contacts at the USB port connection.

Almost certainly a fw problem and/or media issues, which the USB interface stalls on.

Certainly you could either convert to SATA or move the ROM to a SATA PCB and then try and clone with ddrescue. HDDSuperClone or whatever to good drive and then extract the data with some Recovery software.

Good luck!

Some Samsung PCBs have issues with dry solder joints at inductors (there are plenty of examples in this forum). If the bridge is not detected, then that would be the first thing to check. It only requires 2 minutes of effort.

The next thing to check would be whether the bridge identifies as a JMicron device when the SPI flash memory is invalidated. For example, one could short its data pin to ground during power-up.

Samsung PCBs also have UART ports. That would be another thing to check.
