How to Re-Format a Read-Only Drive

By Stephen Lilley

For hard disk drives classified as "read only," you can only view the data on the drive but not edit it. This does not mean, however, that you cannot reformat the drive to uninstall its file system and remove all data from the drive. You can accomplish this at any time using tools native to your operating system.

Step 1

Click "Start."

Step 2

Click "Computer."

Step 3

Right-click the icon for the read-only drive you want to reformat.

Step 4

Click "Format."

Click on a new file system from the "File System" drop down menu. If you don't know what file system the drive should have, leave this box alone as the default file system will always work with your operating system. Click "Start" to reformat your read-only drive.
