I have some issues with a 256GB mSATA Sandisk X300 SD7Sf6s-256G SSD
The drive is powering on, power delivery is good however PC-3000 is unable to detected it, showing as in the photo below.

I checked power points on PCB and power delivery is good. The Marvel CPU is getting warmer when powered, so power is going to it. There are no burnt fuses on it either.
I see that the drive is supported by PC-3000 SSD, however the drive does not go into ready/busy, safe mode...
Is there anything else I could try?
The PC-3000 utility for Sandisk does show support for X300, and also shows support for connecting through terminal. Would anyone know what pins I need to solder for the terminal connection?
