USB write protected - tried everything!

  Sophie2245 20:45 16 May 2019


I would be greatful for any help please:

I have a brand new USB device (brought 4 months ago) and have recently gone to copy and paste some photos over from my laptop to the usb. Shortly after the first few images I have encountered notification that the usb in 'write protected'. As a result it now won't let me copy over or delete any photos. I have tried all google suggestions:

Registry Formatting Wiping the disk clean Changing data values from 1 to 0

I am really stuck with what to do.

Please can anyone help resolve this?

Many thanks Sophie

Write Protected?

  1. go into command prompt or powershell
  2. then type "diskpart"
  3. type "list volume"
  4. then "select volume xxx" (where xxx is the write protected problem drive)
  5. then type "attributes volume clear readonly"

  6. type "exit" to come out of command prompt.

  7. Then try to write to the drive.

Hello Fruit Bat :)

Many thanks for your response - I tried it and it came up with the following:

Virtual Disk Service Error: The operation is not supported on removable media.

Any other thoughts?

Thank you!

you could try downloading and running a registry tweak

or tweak manually, Search for regedit and open the registry edit app

In the registry search for

[HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies] “WriteProtect”=dword:00000000

You will have to create a D-Word (32-bit) key with the value “0” called WriteProtect here:


Create the key StorageDevicePolicies if it does not exist. exit the registry and reboot.

Running the tweak from the link above does all this for you.

retry to write to the USB drive

If you have tried formatting, wiping, changing disk attributes, modifying the registry but totally in vain, you might need to consider whether it is the disk error that causes USB drive write protection. If that's the case, you can run CHKDSK.exe tool to scan the USB drive and fix detected errors. Step 1. Press “Win+R” to open run dialogue, type “cmd” in the search box and press “Enter”, right click the Command Prompt icon and select “Run as administrator”.

Step 2. In the pop-out command prompt window, type “chkdsk g: /f /r / x” to both check and fix errors if found.
