I have a SSD drive in my computer already im trying to up the memory with a 2tb seagate HDD to just store stuff on but my computer isnt registering it...

Anyone have any ideas?

Are you sure you have put the cables correctly? I believe you need SATA and then power from your PSU.

Also try to go into BIOS and enabling it / look for it.

QCK worked good matey thank you very much!

just done the same thing myself, the speed difference is insane!
