HELP! external hardrive problem

I’ve had my hardrive for a couple of years now. In the last couple of days ive gone to use it and it registers that its connected to my computer. For starters it doesn’t come up auto unlock now.Then i go to my computer and try to click unlock from there. Most of the time it becomes not responding. Then the one time i connected to the hardrive it was really slow running then disconnected itself halfway through me transferring something from it. can this be fixed.

For the auto unlock problem see if the link below helps.

To see if the hard drive has any hardware problems, try running a DLG test.
