Question

New My Book, I Backed up My Doc's and MS Outlook Yesterday Morning Using the free trial software. I got 2 err messages. So I went to my computer and clicked on MY book drive and could not view the files. I figured it didn't work and proceeded to try the SYNC software to the same file. The computer has run all night I now have visible files but WD button manager wont let me disconnect. The SYNC program and the Back up program said there was a problem and they had to close. Please Help! Chris
