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!

Format an external Drive.

Hello Roger,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

I would suggest you to follow the below steps to format the drive you are referring to.

• Right Click on Start menu and select Open Computer Management.
  
• 
  In the left pane, under Storage, click Disk Management.
  
• 
  Right-click the volume that you want to format, and then click Format.
  
• 
  To format the volume with the default settings, in the Format dialog box, click
  OK, and then click OK again.
  

Note: You cannot format a disk or partition that is currently in use, including the partition that contains Windows.

Hope it helps.

Thank you.
