HDD Being Wiped?

[OhioYJ]

So my son's PC is setup identical to mine, a large HDD, then another large HDD that is a backup. However I've run into an issue recently where his backup is being wiped. The first time was after the new build, so I figured maybe I accidentally formatted it or something during the install, not big deal. Copied the files back over (They are on backed up in several places anyways). Now it's happened again. I've double check my scripts, and the only reference I can find to F: is

 

robocopy D: F: /E /PURGE /R:2 /W:2 /TIMFIX

Which definitely shouldn't wipe the drive.  Running that line manually does what I expect (Mirrors the drives).

 

Is there a way I can monitor large changes like this, or anything I can search for in the event viewer?

Ok, never mind, something else is going on. So I sat and watched the script run. Something much stranger is going on. I've used these scripts for a long time and they work (well they did). For some reason his started skipping that drive mirror step, at least it seemed it was.

 

I can run it manually and it copies the files. If I run it again, it deletes them and copies them again. Rather than only coping changed or new files. It's like he doesn't have permission to touch that drive.

Pretty certain this was some sort of permissions thing, no idea what though. After deleting the partitions, creating a new one, and formatting the drive, everything behaves as it should. There was probably a way to figure it out, however with an empty drive already, seemed like the quickest way was just nuking it anyways.
