My external hard drive suddenly needs to be formatted?
I have a WD 500G hard drive and it's been working well for me for the last six months. When I tried to use it today , it said that it needed to be formatted. I know that by formatting I will erase all of it contents and I simply can't do that. The weird thing is, is that 7 out of the 8 folders I have on it work just fine. But the most important folder won't open I keep getting a pop up that says it needs to be reformatted. I've tried it on 4 different computers all with the same results. Can anyone help? Thank you for your time
