You do not see an option to create a new folder or file or if you try to copy something on a drive, you get “cannot write to disk”. This can happen to one, few, or all drives.
I confirmed that the disk status was NOT set to “read only” or permissions issue.
Fix using Local Group Policy Editor:
There is a local group policy causing this, so we must make sure that it is not enabled.
- Open Run – type in MMC. Add/Remove Snap in. Select Group Policy Object Editor – group policy Object – select “Local Computer”.
- Local Computer Policy – Computer Configuration – Administrative Templates – Windows Components – BitLocker Drive Encryption – Removable Data Drives.
- Set “Deny write access to removable drives not protected by BitLocker” to “Not Configured”.
Fix Using Registry
- Right click the Control (folder) key, select New, and click on Key. Name the new key StorageDevicePolicies.
- Select the newly created key, and right click on the white space at the right-hand pane. Select New and click on DWORD (32-bit) Value.
- Name the new DWORD WriteProtect.
- Change the value to 0.
- Restart the server.
