I’ve been having this problem off and on ever since these drives (I have two) were new. When I try to run a back-up, either scheduled or on the spot, it just won’t run. I get a message “Backup was completely successfully”. I used to be able to “fool” it by switching from a category-type of backup to a file-type. But now, that doesn’t work either. I’m about ready to dump these and switch to another brand. BTW, I have kept the software up to date.
Anyone have any ideas?
