A long time ago I was building a desktop PC, and I accidentally exchanged the two lines on the motherboard pin header for the front USB ports of an ATX chassis. No matter what I plugged in those ports, it would be detected as unknown device. So make sure that your wiring is correct.

There is a Scorpio SATA PCB #2060-771672-004 REV A that has a Marvell 88i9045-TFJ2 MCU and an SH6601AF motor controller.
It might be worth looking into.

Unfortunately in your case U12 is vacant, so the adaptive data are internal to the Marvell 88i8946-TFJ2 MCU.

Just to recap. The issue as i suspected from the beginning was a faulty USB connector to the main board. The main symptom was that the drive would never mount (only once, with a bit of force) however the drive would get power and spin up and it didn't sound as if it had any internal issues. I ended up removing the mini-USB connector from the main board (thinking i would solder the USB cables in the same spot, bad idea) then attempted to locate the USB pins on the back of the PCB myself. With the help of ciccillover i was able to know for sure the 5+ volt and GND pins. As for the D+ and D-, i had to search for them myself with a bit of trial and error, I found them with a bit of luck!
I've attatched an image of my PCB (WD1T0MVV-11A27S2, 2060-701675-001 REV P1), which is a 1TB Western Digital Passport SE. If anyone has this exact drive model the pins i marked should work for you. Thankfully i was able to go this route since this PCB has an encryption chip on it. It would have been a complete nightmare or almost impossible trying to replace the PCB due to this!
Anyway, i'll recommend to everyone else to bypass the USB connector by going directly to the main board, before attempting a PCB replacement or converting to an SATA drive, if you suspect a faulty USB connector, as it seems this is the majority of everyone's issue.
Last but not least, this is the last time i will purchase one of these good for nothing drives! I highly advise everyone else to avoid these things, you could be in a very unfortunate situation where you risk losing a lot of important, meaningful data. I can't wait to go smash this thing with a hammer!!
Thanks again guys!!
