Cannot access external hard drive

From couple of days I am facing a weird problem. Whenever I plug my external hard drive into one of the USB port it cannot be accessed or seen on my computer. But on the bottom right corner of the taskbar I can see that it has been identified as a "USB Device". I can also see it as a "USB Device" in the Device Manager under Disk Drives. I am using this storage device from about a year ago.

Any help would be greatly appreciated!

Have you tried using different USB ports because there might be chances of your USB port malfunctioning!

Yeah did that but it didn't worked.

Try it on some different computer (maybe your friends or someone else) and see if that works? And remember to make it as a slave when connecting on a desktop.
