My External Hard Disk Drive is not recognized.
Posted on 2014-07-10
External HDD not showing up on computer. Have tried different computers, but works on none.
Have tried different connectors to the USB Socket, and tried different Sockets, but no go.
When plugged in: the External drive lights up and whirrs around, as normal. But it does not show up in the My Computer window.
1. When I connect to the USB port a message appears
'USB Device not recognized',
One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it.
The location of the device is shown in bold type.
-USB Root Hub (6 ports)
Unused Port, Unused Port, USB Mass Storage Device, Unused Port, Unused port, Unknown Device (bold print)
2. When I open Device Manager Window I see under -Universal Serial Bus Controllers' a list of items. One of them has a yellow mark; It reads 'USB Mass Storage Device'.
3. When I click on the Properties of this Item (USB Mass Storage Device Properties) I get the following under Device Status:
'Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer' (code 47).
To fix this problem, unplug this device from your computer and then plug it in again'.
I have done this several times but it makes no difference.
(the device is enabled)
