Understanding Volume Dismounting

Dismounting a volume essentially means safely removing a storage device or disconnecting a storage volume from the operating system. This process ensures that all ongoing processes or read/write operations are completed before the volume is detached, preventing data loss or corruption.

• Press Win + X and select 'Disk Management'.
• Right-click the volume you want to dismount and select 'Offline'. This will safely dismount the volume.

3. Using Command Prompt
