Then it freezes together with the copying process. And after reboot I see errors in the controller's log - they are all exactly same: Function: Media Unlock Error Code: Access Violation User Info: 00000000 Disk Serial No is not set, just no data in the table field Timestamps are somewhat strange - three erroror logs one after another then about 3-4 minutes delay and again three messages The RAID volume sometimes enters a state after reboot where all three disks are working and the cgi says the volume is initializing.
