Hi everyone, I have a Western Digital My Passport external hard drive that is coming up as "corrupt or unreadable" by my home computer (Windows XP). I took it in to work today and their Windows 7 system can read and open it, but I get a message saying some files are corrupt and I should run chkdsk. The reason I'm asking if I should really do that is because when I ran that idea past a friend over the weekend, he declared nope, that might delete all your files. He works mainly with Macs, but now I'm paranoid and would like a second or third opinion here! (And if I backup my files first, will moving corrupt data onto a new drive create this problem all over again?) Thanks!
