I have a WD, My Passport Essentials 500gb hard drive. When My wife & I bought an HP laptop each, I used the external hard drive to make a back-up of both laptops, something I saw in a magazine in case of future problems. recently I decided to use the hard drive to back-up my photo's so possible free up space on my laptops internal hard drive. When I connected the WD to my laptop nothing happened, I went to "my computer" but the WD did not show up. Also I have not been able to see what was on the WD either, nothing shows. Any ideas anyone please.?
