Question SSD disconnecting every time I shut down my PC

[Petrowsky]

I've seen several threads asking about random disconnects, but mine just doesn't recognize one of my SSDs after a shutdown unless I replug the cables into it. The computer (which I built in late December, only keeping the SSDs and the graphics card from my old one) also boots up considerably slower, in just over one minute compared to the usual 15-20 seconds. Waking up the computer from sleep, however, seems to work perfectly all the time, and the drive keeps working until the next power off. Any idea on what causes this and how to fix it? I initially just shrugged it off as a cheap ssd failure of some sorts and kept the side panel off for easy access to the drive, but it's getting really annoying.

SSD: ADATA SU650 960gb
Motherboard: ASRock B450M Pro4

Did you do a fresh SO install with these new parts?

Honestly I'm not an expert at computers so I'm not sure what that entails, but I did try to update everything to it's latest driver, if that's what you're asking.
