ZFS Pool Minor Model & Problem Data Recovery Caselog

02SEP25: RAIDZ1 pool with three ST4000VN008-2DR166 drives. Two (ZM401ZXR, ZDH5N8SG) had dead heads and showed “0003” terminal error. One drive (ZDH5F828) was healthy and used as a reference. ROMs read via terminal, preamp versions confirmed, and tech mode patching applied. ZDH5F828 was cloned to an 8TB donor; head swap planned into ZDH5N8SG for pool reconstruction.
