WD my passport 3.0 recognized but cannot access

I can’t access my hard disk as it is not recognized on some laptops or if recognized on some it takes about 20 min to show in my computers…After all it keeps disconnecting and if any folder is clicked in the disk it hangs the laptop and it becomes all the more irritating…
I have some important data in it which I want to keep…So I haven’t formatted or cleaned it yet…

Please help…!!

Make sure to try a different USB cable to isolate the problem.
