Hello,

1. insert the pendrive
2. dont open or format it directly
3. right click on my computer and go to manage
4.in computer managment window click on disk managment option
5. right click on the removable disk (i,h....)
6. select format

What happens next is that it shows an error message saying that the flash is WRITE protected and cannot be formatted.

Please advice. Many thanks in advance!!!
