New drive not showing up in explorer or disk management

Its a 4TB Barracuda Pro 6 GB/s


It shows up in the BIOS (of course it does) but nowhere else.


When I first went into disk management I got a prompt asking which partition I wanted and I chose GPT, but the drive didn't show up after.


Ive tried different sata ports, memory test (online recommendation)


When I restart or turn on my computer I can hear the windows disconnect sound clip (the ones that plays after unplugging a USB) at the login screen.

Only thing I haven't tried is installing the drivers, and that's because I don't have another PC to assist is things go south.

It wont show until you parition it then format the drive if it doesnt show in disk manger try free paritioning software

Can you recommend one, I have no idea about these programs or what to look for in them

Its still not showing up

Alright, I unplugged my other internal hard drive and plugged in the new one (I didnt do this before because I have programs running/installed on it) and it came up, but when I plugged in the one that I already had, it doesnt show

....the port wasnt enable in the BIOS

yea everything works now, but. both drives are 6gb/s yet the transfer speeds are quite low. (both HDD)
