Question M.2 Drive works great on New build, but can't see other Hard drives

[Bsmooth]

My MSI MPG gaming plus is now up and running. I only had my M.2 SSD drive connected so windows would only load into that. After win 10 is now loaded I shut down and connected my other Hard Drives, but they aren't showing up, but I don't know why. After a new build What drivers need to be installed ?
I also didn't have my network on when I loaded windows, so I wouldn't have to create a Microsoft account. Do I need to load drivers so my SATA drives will show up? Also my DDR memory is only showing as 2333 instead of 3600. My CPU temp is around 30-32C, is that OK ?
I'm sure I'll have more questions, but thanks to everyone so far for all your help.

Make sure that the SATA devices have SATA power too, and make sure that they are not connected to SATA ports that get disabled when you utilize the M.2 PCI-E slot.

As VirtualLarry wrote, make sure you have not plugged the sata drive into the shared sata/m2 connector. P. 35 in the manual.

For your memory to run at 3600, enable the XMP profile in the BIOS. For your hard drive, if it's new, run diskmgmt.msc and initialize/format it.

I relocated the Corsair M.2 Drive to position 1 to open up all the SATA locations.
Sorry I forgot to mention I updated the bios first thing. I think I can see all the drives now, but my Samsung EVO 1 TB is showing up as only having 69 MB free of 99 MB and its being called System Reserved. I was previously using this as my Windows boot drive before but it had 1 TB then, why only 99MB now?
I'm thinking maybe that was the boot partition for windows, and it has to be formatted ? If so how do I format it and clean it at the same time ?

I went under disk management and I found my Samsung EVO drive, but it doesn't show up under this PC. How do I get the PC to recognize it. I read somewhere maybe it needs to be initialized, or maybe on my old PC it happened to get assigned a drive letter that my new PC already has ?

If you don't need the data on it the simplest thing would be to just use diskpart to 'clean' the disk and then create a partition/format it.

Between diskpart:

How to Diskpart Erase/Clean a Drive Through the Command Prompt | Seagate Support US

And Disk Management:

Overview of Disk Management | Microsoft Docs

This should give you everything you need. If you need the data on it then assigning a drive letter to the partition via disk management should be sufficient to make the data accessible.

I'm all set now, thats what it was it just needed initializing, weird it was the same drive I was using on my last PC and it was working fine.
