My external hard drive does not show up in “My Computer”?

I recently formatted my hard disk. When I plug in my external hard disk USB (which was working fine prior formatting the PC), it does not shows up in 'My Computer'. When checking Device Manager, the device is working properly. I have verified on Disk Management, the external hard disk is there but with no Drive letters and paths, it mention "unallocated".
The light on the external HD is ON and the I can feel the spinning.
The external HD is an Apollo 2.5" portable hard drive 250GB.

Can anyone help me on the above issue. All my back up data is on it.

    usb ports wear out, try another port, or wiggle it gently

    Well if it doesn’t have a drive letter or path then maybe that’s why it isn’t being shown in “My Computer. ”

    Have you tried giving it a drive letter in Disk Management?

    have you checked in BIOS if drive is recognised, if you have formatted hard drive, possible USB driver problem, easily proven if all USB ports are same result? You can rectify it in disk managment, by allocating it a letter and name ie “apollo”, just so you know that iit is that drive. Your data will be there as long as you don’t reformat the external

    there are so many solutions for it you have to format it otherwise try it on any another system. . .

    Unallocated means its not formatted, if you format it then it will work fine. but you told all the back up data is in it, what will you do?? Did you attached the drive while formatting your system??, that’s why the problem occurred.
