Step 2. Find and right-click the SSD you want to initialize, and then click "Initialize Disk".
Step 3. In the Initialize Disk dialog box, select the disk(s) to initialize. You can select whether to use the master boot record (MBR) or GUID partition table (GPT) partition style. If you wish to use this disk as a system disk, you can directly choose GPT.

Unlike the above situation, the possible reasons that make your current SSD/HDD not show are various. So we list some methods to help you.
Method 1. Assign a new disk letter
SSD not appearing may be caused by the SSD's drive letter being absent or clashing with another disk, causing the Windows OS to fail to identify it. You may resolve this issue by manually assigning a new drive letter to the SSD in Windows Disk Management.
Step 1. Right-click on "This PC", and select "Manage". Under the Storage section, click "Disk Management".
Step 2. Right-click on the SSD partition and select "Change Drive Letter and Paths…".
Step 3. Among Add, Change, and Remove, click the "Change" button, and then select a drive letter from the list. Click "OK" to confirm.
Method 2. Update drivers
Another condition of SSD not showing up is if it's running on outdated drivers. Try to update the SSD driver to check if this helps fix the issue.
Step 1. Type "Device Manager" in the start-up menu's search field. Click on "Enter" to launch it.
Step 2. Go to the Disk drives, and right-click on every item under it.
Step 3. Click on "Update driver." Then reboot your PC.
Method 3. Format the disk
If the file system has corrupted, your SSD will also disappear from your PC. You may see your disk marked as RAW or Unallocated. In this case, you’ll have to format your disk. The operation is the same as formatting a new SSD.
Step 1. Go to This PC or Disk Management, and right-click on the RAW partition or drive, select "Format".
Step 2. Set Volume Label, File System (NTFS), and Allocation unit size. The default format option is Quick Format. Then, click "OK" to start the operation.
