External Hard Drive Does Not show up in Explorer

Hi
I recently bought a New External Hard drive.
When I first bought it and plugged it in I saw it in Windows explorer
I used HD Clone to make an Identical copy of my PC Hard drive and it copied sucessfully.
Now I cannot see the Har drive when I plug it in the USB 3.0 port
I tried using other USB ports and had the same problem.
All I here is the small sound that windows make when I plug in the Hard drive, but the Hard drive does not show up in Explorer.
I know the Hard drive is there because HD Clone recognized it.
Can some please assist me
Thanks in advance.
The External Hard Drive is 1Tb, and my PC Hard drive is 500 Gb
Im using Windows 8

Drives usually don’t show up unless they are A) formatted and B) have a drive letter assigned.
go to start > run > enter without the quotes “diskmgmt.msc”. It should be listed there at least (if it isn’t, its defective), then just format it, assign a drive letter and it should show up.
Answer #2
use any partition application to assign a drive letter to your external drive.

But I already went thru Disk management and Formatted the Drive before I Clone my PC Hard rive unto it.
I tried to Assign a Letter to it but that option is all greyed out (when I right click on it)
It does show up on Disk Management and also Device Manager
DVM shows that Nothing is wrong with the Drive.(And is working correctly
(the Drive is only 3 Days old (Bought it Brand New)
I Hooked the same External Drive to a Laptop running Win 7 and it recognized it and I could the Whole Cloned PC Drive (all Files everything)
It Just that my Win 8 PC does not show it up in Explorer. But it Does Show info on it on the small Icon to the Bottom right of the screen) that give option to “To Eject USB Hard Drive”.

You could try uninstalling it in Device manager.
Then reboot and see if it comes up better.

if you are sure that it was available on explorer menu for at least once , this is your solution. you need to remove it from device manager , as well as all registry entries.

this software will help you to do it. keep in mind you need to plug out all usb devices(except mouse and keyboard) including your harddrive during to process. and restart system after cleaning is done then plug in harddrive. you also need to run application as administrator. you will only remove the external harddrive entry , if you remove all usb devices you may need to re-install drivers for some of them for recognition
“In order to disable/enable USB items on x64 systems, you also must use the x64 version of USBDeview. ” so download according to your system.

Can you try using EaseUS Partition Master?
