This caught me out yesterday again as I have a shared Steam folder on a NTFS partition so that the game download once and run from Windows 10 or Linux. I mostly play in Linux but World of Tanks had some issue accessing the online store and that only seemed to work if I booted into Windows proper. Windows is now often defaulting to going into hibernation mode which does not properly release that NTFS partition, so that when you later want to run Steam you may find the shared folder is not appearing or you see an error saying there is a problem with permissions. Basically, the partition is in read-only mode.
There is a way to force it closed, but a simple way is to just restart Windows and make sure its Power Options exclude “fast startup” is disabled. Now when shutting down it releases and flushes everything to the drive, allowing safe mounting on the Linux side and ensuring changes to files won’t corrupt anything that was in a hibernation state.
