Hello, thanks, dear sir but It’s giving me an error
This is way does not show the drive letter. Now, what can I do?
Try this:
run >> cmd
type “diskpart” (no quotes of course)
type “list volume”
You will see a list of all available volumes that are attached to your computer. Look for the one that does not have a drive letter and make note of its volume number.
Type “select volume #” where # is the number of the volume that you need to give a drive letter.
type “assign” to give it the next free drive letter.
type “exit”
That should do it.
