I delete the driver from Device Manager and reconnect the driver and re-isntall a new version
When I go to my computer \ Manage \ disk managemnet it show as Disk 1 when I try to format or delete volume it freez and nothing happend
The light is ON on my HD and I can hear the sound of the drive is working fine
