Windows 10: USB both invalid and write protected

Hello,

Somehow my usb key is both invalid and read only after copying some pictures on it from a mac, and displays as two disks with the same number.

I've tried using diskpart and regedit to take the write protect off, but it hasn't been working. I've also tried right clicking on the disk but the only thing that isn't grayed out is "offline" "properties" that says that the USB is working properly and "help".

I'd like to know what I can do to get the key to function properly again?

I don't care about retrieving the files on the key, there's nothing important on it as it was pretty much brand new, I just want to retrieve the key.

Thank you!




:)

USB devices getting write protected

Hi Imdad,

Some removable storage devices like USB flash drives or pen drive have write protection which is designed to help users prevent unexpected data loss by refusing to delete or format.

However, if you’re stuck with a write-protected USB drive that can’t be formatted. We recommend that you follow these steps on how to erase and format a write-protected USB flash drive and pen drive using the Regedit.exe tool in Windows. To do this,
follow the steps below:

• In the Search box, type regedit and press Enter.
• Navigate to the following folder:
  
  Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

Double-click on the WriteProtect value in the right-hand pane of Regedit.exe. Change the Value data from 1 to 0 and click OK to save the change. Close Regedit and restart your computer. Connect your USB flash drive or pen drive again, and you should find the
write protection is removed and the device is no longer write protected.

Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection,
back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, refer to the following Microsoft Knowledge Base article.
