Question My PC doesnt recognize HHD since I installed M.2 SSD

[Aca1911]

Hey guys. Today I bought M.2 SSD 240gb and I installed it on my motherboard (Aorus B450M) and I wanted to restart my PC, so when I got to the section to chose where I want to install my windows there was only 240gb of SSD (there was not a choise for 1T from HDD). I tought its ok, cuz I wanted to install it on SSD. When it was done I opened My PC and there was only 1 parition C of 240gb and I wanted to make 2 more of 500GB from HDD so I went to My PC>Manage> Disk Manager and there was only that 240GB from SSD, there is NOT HDD. Here is picture;

Using an M.2 device will disable a few SATA ports on that motherboard my guess is your HDD is plugged into one of those disabled ports. So try a different SATA port on your mobo for the HDD. Page 16 in your mobo's manual.

Some SATA ports are disabled when you install M2's. See chart.

Well I just tried to change HDD SATA cables in both of them and still doesn't work

Well you installed a M.2 device which disables sata ports then realize your HDD no longer works. So unless your HDD picked that very unlikely moment to die that must be your issue.

What should I do now? I need that 1T of memory in my PC and also this new SSD
