In Windows 11, “mounting” a drive can mean assigning a normal volume a drive letter, attaching a virtual disk, or opening a disk-image file. For a physical storage volume that Windows detects but does not show in File Explorer, Disk Management is the usual tool.
Assign a drive letter to an existing volume
- Right-click Start and open Disk Management.
- Identify the correct disk and existing volume by its size and layout.
- Right-click the volume.
- Choose Change Drive Letter and Paths.
- Add an available drive letter and confirm.
The volume should then appear in File Explorer if Windows supports its file system.
Do not initialize or format a drive with needed data
If the disk contains files you need, do not initialize, delete partitions, or format it merely because it does not appear in File Explorer. Those operations can destroy existing data or partition information.
Mount an ISO file
If by “drive” you mean an ISO disk image, right-click the trusted ISO file and choose Mount when Windows provides that option. Windows creates a temporary virtual optical drive containing the image’s files. Eject that virtual drive when finished.
Encrypted volumes require their legitimate unlock credentials. A drive using an unsupported file system may need compatible software or another operating system rather than reformatting.
