We recently got a message from a user about a corrupt DataGraph file on a Microsoft OneDrive volume.
Searching online it does look like this is a problem with a recent update, and in particular on 12.1 or later. See link on macrumors and this microsoft link
If you are OneDrive user please be aware of this. If you have problems with OneDrive please let us know and include info about which OS version and OneDrive version you are using. If you have no problems, we would like to know that too.
Some suggestions
– Make sure you still back up your folder using TimeMachine, Carbon Copy Cloner or something similar.
– Move your files off OneDrive and onto DropBox or iCloud (no reports of issues with them) or just a normal folder.
