SSD issues

Greetings

I picked up a Samsung 870 EVO, hooked everything up, booted the machine, and confirmed the drivers are installed. Everything looks fine on paper, yet the drive refuses to show up in File Explorer.

It didn't seem like a major issue at first since I could locate it in the Device Manager. I went into Disk Management, selected the unallocated space, and attempted to create a new simple volume. I left the volume size alone, assigned it the drive letter Z, kept the file system as NTFS with default allocation unit size, and checked the box for a quick format. I hit finish, only to be met with an error stating, "The device is not connected," and just like that, it vanished.

Now, it isn't even appearing in the Device Manager anymore, unless I manually trigger a scan for hardware changes, which brings it back momentarily.

When I attempt to repeat the process in Disk Management, I'm greeted with: "The specified network resource or device is no longer available."

I have spent a significant portion of my evening chasing this ghost. I will admit, I am not exactly an expert in these matters, and I foolishly assumed this would be a straightforward task... Does anyone have any insight into what might be causing this failure?

P.S. If this is entirely my own doing, feel free to tear me apart...

Try heading into your BIOS to see if the drive is actually being detected—and if it isn't set to AHCI mode, you should definitely switch it over to that. I mean, you're going to have to install macOS on it anyway, right? Once you get to the OS installation stage, the installer needs to be able to see the partitions on the drive so you can actually pick it as the destination for your installation...

No, I already have one of the 60GB drives with macOS installed on it

Hey
Is that second—or newer—SSD actually showing up in your BIOS settings?

Just wanted to let you know that I finally figured it out. After spending over an hour messing around with the SATA cable from the optical drive, everything is running perfectly fine. However, trying to use any of the vacant SATA ports? Absolutely nothing works...
