Cant format flash drive write protected

Does your flash drive have a switch to turn off write protection?

hi guy it's very easy
for tricks of USB devices

here are the instructions::
Go to registry editor:
Start, Run, type "regedit"

Find the following key: HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ StorageDevicePolicies
Create a REG_DWORD value named WriteProtect and give it the value 0.

and if you want to protect it you have to put 1 instead 1

My key is doesn't have StorageDevicePolicies,what should I do?

Hi,

No, you cannot format a write protected USB drive. You have to disable write protection, usually accomplished by flicking a ‘switch’ on the device.
