Problem with WD Elements SE 500gb

[superinz]

I have my WD Elements SE500gb for 2 to 3 years for now but one day it happens to become unrecognizable by my PC. I see in this forum that i should download WD Quick Formatter so i do it but I wait so long but it cant says it cannot complete the format. After doing this, I can see it my computer but it cant be format again. I am not interested in the files in it. I only want to format it and use it again. Can someone help me with my problem?

You can try writing zeroes to it, then reformat it.

Sir my problem now is that my external hard drive can't be detected by my computer. I am sure that the usb cable is working and I plugged it correctly on my computer.

Try using a different cable
