Noises from hard drives usually mean they have failed mechanically. Nothing you can do but replace it. Might try a better manufacturer - the reviews I saw were not too good.

If you have important data on it you could try this:
No guarantee it will work though - depends how bad the HDD is.

Always pop back and let us know the outcome - thanks

Buy an external hard drive manufactured by a hard drive manufacturer so you know what you're getting inside it (Adata do not make hard drives, they just make the enclosure, the hard drive inside it could be from any hard drive manufacturer).

I recommend you buy a Western Digital model such as the "My Passport" or "My Book" series.

Another things that can cause this is the USB interface board within the enclosure. The hard drives are usually SATA and the enclosures are USB or micro USB rather. The board that does the conversion can fail meaning that the HD will not be recognized by the PC.

What you can do is, remove the drive from the enclosure and plug it into a hard drive dock (look on Amazon) or directly into the PC.

The buzzing sound is normal, its the initial spin up of the disk motor inside, if you hear clicking then, that's the time to start worrying.

As mentioned above, get a better brand, WD are probably the best.
