Copy aborted because volume cannot be found

Let me phrase this differently: if it is possible that any of the above apps changed something on the drive that makes it impossible for SD to locate it, would it be an option to implement a schedule feature that only checks by a drive’s name? As I said, I’ve not erased the drive... only used the above mentioned apps on it. And SD. That’s it. I now remember that I did have to redo the schedule shortly after purchase, so this wasn’t the first time. I guess the culprit might be iDefrag or TechTool Pro if this is of any help to you.
