One cheap and easy way for a disk acquisition without the need to buy an expensive physical write-blocker is using a USB external drive or a cable-connecting device (USB IDE/SATA external connector) along with changing the Windows Registry key to enable write-protection.

To update the registry, there are 3 tasks:

  1. Backup the Registry in case something fails while modifying the keys.
  2. Modify the Registry key to enable the write-protection feature.
    1.   Go to (\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet)
    2. Right-Click the Control Key -> New -> Key
    3. Type in the Key Name: StorageDevicePolicies
    4. Press Enter
    5. Right-Click the newly created key called StorageDevicePolicies -> New -> DWORD Value
    6. Type at the right side, WriteProtect
    7. Press Enter
    8. Right-Click the newly created Dword value and click on Modify
    9. Change the value from 0 to 1
    10. Click OK

NOTE: you can export the key and save it for future uses to simplify the process of updating the Registry Key and also to minimize error every time you need to write-block a USB device.

  1. Save the exported Registry Files for future uses.
