My external hard drive is nor being recognised by my computer…

My external hard drive is nor being recognised properly by my computer. It is beeing accepted so far as it makes the “beeping sound” when you plug it in but all that comes up on My Computer is Removable Disk (E:) which has no memory and refuses to be opened. The harddrive does not bring up its logo either, the blue WD sign, and apart from the Removable Disk (E:) bit is not recognised at all. I have tried changing the cble but that has done nothing either.. Any help would be really appreciated
