I realized yesterday that my WD Passport Drive had not backup up anything since November 2014. I reinstalled the drivers and allowed it to back up files. It has now been backing up files for over 15 hours and I don’t see a lot of files from post November 2014! It is still indicating that it is backing up files, but this is very worrisome. How long should it take to do a full back up and why has it not yet backup up recent files? I would greatly appreciate any and all help and advice in this matter.
