I recently built my first PC with an MSI Godlike x870e motherboard, and I'm having trouble with my SSD setup. I've got two SSDs: M_5, which has Windows 11 installed and works fine, and M_1, which shows up in the BIOS but doesn't appear at all when I'm in Windows. I'm really stuck on what to do next.

It sounds like M_5 is your main drive with Windows installed. For M_1, try checking if it's showing up in Disk Management. Sometimes, drives need to have a letter assigned to be visible in File Explorer. If it’s not appearing there, it might not be detected by Windows at all.
As this is your first build, here’s a tip! It's usually best to install Windows with only the intended drive connected. If you had both drives hooked up during the install, Windows might have put the boot files on M_1 instead of M_5. I recommend unplugging M_1, reinstalling Windows on M_5, and then plugging M_1 back in afterward. If it doesn’t show up then, you can initialize it in Disk Management.
