Sata SSD Not showing after install

I have an aspire 7 a715-72g-79r9 (purchased from manufacturer). It came with a 256gig M.2 drive, there is an empty bay on the bottom to add a Sata drive. So being I do alot of photography I wanted to put an additional drive in for extra storage. I purchased a Crucial 1tb Mx500 SSD (model: ct1000mx500ssd1) and put it in the bay. I turn on the computer (Before i knew they were hot swappable) and nothing. The drive isn't even there. Not in BIOS, not in Disk management. I can connect VIA USB to Sata cable and the drive shows. I have sent the computer back two times now and they claim there is no issue with the unit. Their drives work just fine. I had a buddy put in is 128Gig drive in and nothing. What gives?!?! I've updated windows, I've upgraded BIOS, I've used the Crucial Application to format the drive when connected via usb and make sure firmware is up to date. I am really stumped as to why this thing will not recognize the drive! I just want to start using this thing. Its been out of my possession longer than I've owned it! maybe you guys can shed some light on the situation

OK! You said that "he drive isn't even there. Not in BIOS, not in Disk management". But does the ssd appear in the information tab of the bios?

That's a good question. BecauseI don't know where that is or how to get it. I don't see any drive in bios besides the of one that came with it

Oh that is the information tab. So no. It doesn't show up there

Have you checked that the sata cable is connected correctly to the motherboard?

I did check, I didn't disconnect and reconnect it i jsut inspected it. Apparently ACERs drives work fine though. I will, when i get a chance I will open it up remove the cable and reconnect it.
