external usb hard drive
the mechanical device is working but i ca not see the drive why?
Check in "Disk Management". It may just need a letter assigning to it.
If you see the ribbon which is labelled "Raw", that will be your external hard drive.
Right-click on that & choose "Change Drive Letter & Paths".
Accept default letter or choose another one.
Click 'OK' and wait 5-10 seconds.
