I've seen some similar things here but I cannot find the exact problem nor the solution.
I recently moved to another computer and my back up drives on the external enclosure was connected.
I had 2 drives in the backup being written to but one was being used by the previous computer and will come up with an error on the new one.
I set up a test folder which can be seen in the attached graphic.
The "RecycleBin~59c0.ffs_tmp" is only created when the backup has started and disappears when. I cancelled. I have tried deleting it and retrying and it just re-creates it. I have tried changing ownership of the folder and permissions and nothing seems to help. This drive is will not allow a mirror backup where something on that drive needs to be deleted."H:\Wacom Driver\Read Me.rtf" to
"H:\Wacom Driver\RecycleBin~59c0.ffs_tmp\Read Me.rtf".
ERROR_ACCESS_DENIED: Access is denied. [MoveFileEx]
The test is an unrelated folder which I decided to see if it's a problem just in the back up folder. This proves that this will happen on that drive regardless - the "Wacom" folder was NEVER part of any FFS backup routine on my other computer
The actual name of the RecycleBin~59c0.ffs_tmp will change to have different numbers after the tilde sign.
Any ideas how I can get out of this mess without formatting the drive completely and starting again?
