|Have you, or is it possible someone else, dropped this external hard drive ?|
Are you trying to get this external drive to work with a desktop computer, or a laptop or netbook ?
What is the make and model of the external hard drive if it was pre-packaged (the hard drive was already installed inside of it), or if you bought an external drive enclosure and installed a hard drive in that, what is the make and model of the external enclosure ?
If the external hard drive has a 3.5" drive installed in it, you MUST plug in the external power adapter that came with it into the external enclosure and that power adapter must be working and there must be nothing wrong with it's wiring or it's plug on the external enclosure end.

If you have data you do not want to lose, you should store the same data in at least two different physical locations !.
If the circuits of the external enclosure are damaged, if there's nothing wrong with the hard drive inside of it, that hard drive will work fine if you remove it from the external enclosure and connect to a computer one way or another.
If it's a SATA hard drive, that's easy, The SATA power socket and SATA data socket are identical on all SATA drives. The drive can be connected internally to any desktop computer that has a SATA data header (by using a standard SATA data cable) and a spare SATA power connector on the power supply's wiring.
When you connect it to another computer, just don't boot from your hard drive on that computer.
If there's nothing wrong with the hard drive itself, hard drive enclosures are not expensive and are available locally.
FYI, it's quite RARE for the hard drive itself to beep, but that is possible. E.g. I heard a friend's desktop Maxtor hard drive do that while failing.
