OK - random! I've restarted the PC seven times so far. Nothing worked. Restart #8 (third restart after the steps above - nothing done to try and fix the issue between restart #6, #7 & #8) and the permissions are back to normal (and I am allowed to change permissions on a file & folder level again). One of those mysterious quirks that has fixed itself.

Hi, So, I went to bed last night and everything was working fine (as it has done for a long time). I woke up this morning and found I couldn't put new files into a folder... weird! Let's try another folder... no. Well, to cut a very long story short I cannot: - Add files to any folder in my drivepool. - Add new folder to my drivepool. - Move/Delete/Edit any existing file in my drivepool. The 'owner' is now a string of random letters and numbers (note, I have made no changes to Windows 10, not changed my account or tried to change any permissions before this issue arose). This only applies to the (95TB) Drivepool, my other drives are all fine - limiting the issue to my Drivepool alone. I have tried numerous ways to change the ownership 'back' - all fail: - ...>Security>Advanced (at file, folder, drive, root, mount levels) - 'takeown' within an elevated command prompt. - TakeOwnershipPro - TakeOwnershipEx - ResetPermission - http://community.covecube.com/index.php?/topic/857-unable-to-write-files-or-update-permissions-on-folders-in-pool/ - All of the above with my standard (admin privalage) account and I've also enabled the default local Administrator account and used that. Neither worked. The fact that this only applies to the drivepool and affects only files handled by the DrivePool software reasonably leads me to believe this is a consequential factor. I cannot create a new pool and move the files into it one drive at a time because I don't have "permission". Can you please help?
