A brand-new SSD does not show up in File Explorer until you initialize it and create a volume in Disk Management. Initializing a disk erases it, so only do this on a new or empty drive.
Quick Answer
Right-click Start, open Disk Management, choose GPT in the Initialize Disk prompt and click OK. Then right-click the unallocated space, choose New Simple Volume, and format it as NTFS.
How to Initialize an SSD in Windows 11
- Install the SSD and start the PC.
- Right-click Start and select Disk Management.
- In the Initialize Disk prompt, select the new disk and choose GPT, then OK.
- If there is no prompt, right-click the disk label (such as Disk 1, Not Initialized) and choose Initialize Disk.
- Right-click the Unallocated space and choose New Simple Volume.
- Follow the wizard: assign a drive letter, choose NTFS and a label, then Finish.
GPT vs MBR
| Partition style | Use |
|---|---|
| GPT | Modern PCs, drives over 2 TB, UEFI boot |
| MBR | Very old PCs or legacy boot only |
| NTFS | Windows internal drives |
| exFAT | Drives shared with Macs |
| Initialize | Only new or empty disks |
Troubleshooting
- SSD not in Disk Management: check the cable or M.2 seating, and enable the slot in firmware settings.
- Initialize Disk is greyed out: the disk is already initialized. Create a volume instead.
- Drive shows the wrong size: it may have been initialized as MBR; convert only if empty.
