Write protection serves the valuable function of securing the data of a disk drive. With write protection enabled, files cannot be modified on a disk drive. Yet you may wish to modify some files on such a drive. In this instance, you can easily disable the write protection of a disk by using the built-in functionality of Microsoft Windows operating systems.
Physically unlock the disk. Just like floppy disks have a physical lock, some modern disk drives contain such a feature. Locate the lock on the disk and place it into the unlock position.
Plug your disk into your computer. Turn your computer on. Click "Start."
Type "Regedit" into the search box and hit "Enter." Type "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies" and hit "Enter." Double click "WriteProtect." Go to the "ValueData" box and type in "0." Click "OK." You have removed write protection from your disk.
