Getting this error while backing up to flash.  Noticed this error came up in 2020 but that discussion is now locked.  Installed latest version update and can backup to hard drive but getting the error message while backing up to flash drive.  Actually back up to two flash drives, H and J.  No problems on H, but cannot get around this error message on J.  Have run chkdsk and clpack on J flash drive but not working.
