Hi there Darwin22,
Sometimes beeping in external drives could bean faulty cable. So, it may be a good idea to connect the drive with a different USB cable to a different port.
If the issue persists, then I guess there is either something wrong with the enclosure or the drive itself. In this case, and if the drive is still under warranty, I would advise you to contact the drive's manufacturer and eventually RMA it.
In case you need the data stored on it, you may need to contact a data recovery company(as you will most probably not be able to access it with software tools).
Cheers,
