I don't know what else to try as Utilities cannot find problems and disk imaging with Winclone works OK.Īny suggestions welcome as I have exhausted my list of things to do. Indeed I have been backing up on this machine for over two years without problems. No disk errors are displayed yet I ran Acronis backups a week ago with no problems. I have also downloaded a copy of Acronis 2017 and reinstalled it.
I have tried different disks, run First Aid on the MacBook and destination Seagate disk, deleted the backup and tried to start again.
