Let me check the link. Only ada2, from other google search, some mentioned that 184 end to end sometime might be OK. I am thinking about taking both drives offline to be on a safe side especially ada1 error count is increasing. Currently I am migrating data out.Did you check the two Seagate page links in the ada1 smart report? The second link has the detailed upgrade instructions, the first should tell you/confirm if SD1A is the latest.
Do you have ada2 AND ada12 with End-to-End "Failing Now"? Your first post had the Alert System pasting showing ada2, the smart tests you made had ada12 but not ada2.
Thanks,
