How To Format A Write Protected Flash Memory ?

¿You already tried this one?...

Run CMD


1. diskpart
2. list disk

Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

2. select disk #
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exit

with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

good luck!

 

Lost ability to view extrenal hard drive

Hello Scott,

Thank you for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.

Before assisting further, I would like to ask you few questions:

• Is the drive visible under Disk management?
• Have you assigned a drive letter for the external drive?
• Does the drive get detected on connecting the same to another PC?

You might be facing the above issue due to the unallocated letter for the drive. Unallocated drives are those whose drive letters are not allocated when initially partitioned or after formatting. You will be able to view the drive on your PC if you
have allocated a drive name for the partition created. The drive will not be visible on the PC if you do not allocate a drive letter or a drive name.

The issue may also occur due to some of the system components conflicting with Windows 10 operating system on the PC.

Method 1: Running the troubleshooter will help in detecting and identifying the issue and in certain cases will fix to enhance the performance of the system.
I suggest you to run the Hardware and Devices troubleshooter by following the steps below and check if the issue is resolved.

• Press Windows logo key on the keyboard, type troubleshooter and select the top most search result.
• Click on View all from left side panel of the screen.
• Select Hardware and Devices, click on Advanced
  option and check Apply repairs automatically option.
• Follow the on screen instructions and wait for the troubleshooting to complete.
• After troubleshooting is completed, check for the status, close the window and check if the changes are effective.

Method 2: If the issue persists, I suggest you to check if the device gets detected under
Disk management by following the steps below:

• Press Windows logo + X keys on the keyboard and select
  Disk management option from the context menu.
• Check if WD external hard drive is visible in the window.
• If visible, check if you can open the files in the File Explorer by right clicking and selecting
  Open option form the context menu.

Write to us with the answers to the above questions and the status of the issue on the same post for further assistance. Your reply is most important for us to ensure we assist you accordingly.

Thank you.
