I didn't know it until this morning but I am having problems with my back up hard drive. My computer doesn't seem to want to acknowledge that it is there. I know it did at one point. I had the backup drive set up as drive F, and had back up software set to run a backup of my main harddrive to my backup hard drive every monday morning. I just realized today that I have not been able to do a complete backup since 01/16/2012! the backup software log says: "Can not access F:\ The system cannot find the path specified" Drive is just not showing up in the list of disk drives. I do not have any idea what the $#%^ happened. It is plugged in just has it has since I installed the backup harddrive over 4 years ago. Any one got any advice?
