Hello Roger_007, I am going to send you a private message and if I can get you to send me the drive dump logs so that I can review them that would be great. Please let us know if you have any other questions.
Backup software is asking for clean order after every usage of drives. We are getting “media write error” messages, drives are marked as offline. I have the logs.
