I assume ada0 is your system disk and you installed via "Auto (ZFS)"? Unrack and rack the drive or tray, if racked. Remove and install drive from tray, if in tray. Disconnect and reconnect the drive power and data cables in chassis. Use cables with locking connectors, if available. Make sure all connections are fully seated and/or locked. Make sure your bus adapter, data cable, rack, and/or tray are all rated for the same data speed, and it is at least as high as the data speed of the drive. If problems persist, download your disk manufacturer's diagnostic tool and start testing different ports, different cables, different racks, different trays, and different drives to isolate hardware problems or verify everything is good: https://www.seagate.com/support/downloads/seatools/ https://support.wdc.com/downloads.aspx?p=2 If problem persist, reply to list with problem description(s) and console session with the following commands: # freebsd-version ; uname -a # geom disk list ada0 # zpool list zroot # zpool status -v zroot David
