HOW TO FIX THE WRITE-PROTECTED ERROR
We use removable storage devices a lot on a Windows computer, and some of you may encounter the issue of the disk malfunction, which is mostly about "the disk is write protected". When Windows starts to write protect your disk, for example, a SanDisk 4GB USB flash drive, you can no longer use it anymore until you remove the write protection. The fixes are as follows.
Method 1: Diskpart command
Step 1: Open administrative Command Prompt.
Step 2: Type these commands one by one and press Enter key after each:
- diskpart
- list disk
- select disk # (# is the number of USB drive with which you're getting the write-protected error and is plugged in, see screenshot below)
- attributes disk clear readonly
Step 3: You may now close Command Prompt and re-plug the USB drive and check if the issue is resolved, by dragging a file to the drive or trying to format in Windows Disk Management or EaseUS Partition Master coming in the later part.
Method 2: Regedit.exe
Step 1: Press Windows Key + R keys simultaneously, type "regedit" in Run dialog box and hit Enter to open the Registry Editor.
Step 2: In the left pane, navigate here: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
Step 3: In the left pane of this location, right click Control key and select New -> Key. Name the new sub-key so created as StorageDevicePolicies. Now come to the right pane of this sub-key i.e. StorageDevicePolicies, right click and select New -> DWORD Value. Name the newly created DWORD as WriteProtect. In some cases, you might find that this DWORD under the sub-key already exists and the DWORD has a Value set to 1. Double-click on the DWORD to modify its Value data.
Step 4： In the above-shown box, change the Value data to 0 from 1. Click OK. Close the Registry Editor and check if the issue is resolved by dragging a file to the drive or trying to format in Windows Disk Management or EaseUS Partition Master coming in the later part.
