A network shared drive is usually a local disk or external disk attached to a Windows PC, server, or NAS-like workstation and then shared over the network. Formatting decides the file system, while sharing permissions decide who can access the files. For Windows sharing, NTFS is usually the best choice because it supports permissions, large files, and reliability features.

Prepare the disk first, then configure Windows sharing. Formatting controls the file system; sharing permissions control who can access the data.

Step 1. Select the drive or partition that will become the network shared drive. Confirm its capacity and drive letter before formatting.
Step 2. Choose Format, set NTFS as the file system, and enter a label such as SharedData.

Step 3. Preview the formatting operation and confirm the correct drive is selected.
Step 4. Click Proceed and wait for the format to finish.
Step 5. Return to Windows, create a folder for shared files, right-click it, and open sharing settings.
Step 6. Add the users or groups that need access, then set read or read/write permissions.
Step 7. Check NTFS permissions on the Security tab as well. Test access from another PC with a normal user account.
A shared drive needs both the right file system and the right permissions. Format it as NTFS for most Windows networks, then configure sharing after the disk is ready.
