Installing SSD Nitro 5 and windows isn't recognizing it or can't find.

What is the exact Nitro 5 model number it should be AN515-xx as the 980 M.2 SSD should work even if your Nitro 5 models M.2 slots are not PCIe 4x4 M.2s.

There are a few requirements for a hard drive to be available in File Explorer. The device must be online and initialized. It needs to have a partition properly configured. And it has to have a drive letter assigned, or it should be mounted as a folder.

If you are dealing with any of these problems, the steps below will help you to troubleshoot and fix the most common issues with Disk Management.

Set drive online

1. To bring a hard drive online, use these steps: 
2. Open Start.
3. Search for Disk Management and click the top result to open the app.

Right-click the disk with the "Offline label" and select the Online option.

After you complete the steps, if the hard drive was offline and previously configured, it should appear in File Explorer. If the storage was offline but never configured, continue with the steps below.

Initialize drive - To initialize a hard drive on Windows 10, use these steps:

1. Open Start.
2. Search for Disk Management and click the top result to open the app.
3. Right-click the disk with the "Unknown" label and select the Initialize Disk option.
4. Under the "Select disks" section, check the drive you want to initialize.
5. Select the "GPT (GUID Partition Table)" option.
6. Click the OK button.

That is all that you have to do, as all new drives have to be installed this way, I've upgraded my 512GB oem M.2 drive on my Nitro 5 AN51557 with a faster WD SN1TB SN750 M.2 SSD and this is what i did and it works 100%
