I ran chkdsk, found some problems, repaired them. Afterwards the same Operation Failed from WinToUSB. It remains for quite some time at 2% and then gives the error message, showing 100%. Did this several times, now the file system on c: is always reported to be clean, and WinToUSB always fails with the same error. User.log is attached.
