One additional item may or may not be relevant is that when I booted up Win10 and powered up the two drives I saw a flash message about hard drive collision which I understand to mean the drives were being accessed at the same time and should never happen. This also occurred last update.
Every little detail helps. Hopefully that type of information will be as forthcoming from others. While the logs are so important for developers to determine the cause of an issue, behaviour and habits unfortunately are not recorded in them. While I don’t use NTFS drives with LE I too am curious what is causing this issue for some and not for others.
