If it is sandisk, change setting on drive to unprotect.
Or, use this registry tweak to remove write protect on USB device.
1.Enable and Disabling of USB write protect using regedit
Enabling USB write protect
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]
“WriteProtect”=dword:00000000
Disabling Write Protect
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]
“WriteProtect”=dword:00000001
