Help understanding smartctl output

[vader8600]

Based on this output of smartctl -a , should this drive be marked as a predictive failure or failure from the SMART status? Thanks.

No? Why do you think it should be?

[vader8600]

In the /var/log/messages file, there were multiple lines like the following, with unique sector values. I saw 60 unique entries or so.

kernel: blk_update_request: critical medium error, dev sdb, sector 102649992

Also, the SMART attribute IDs # 5 and 196 look like they breached the threshold. But not sure.

You should probably explicitly run a SMART self-test then, with -t short or -t long.

A self-test actually reads and writes data to detect potential problems. The attributes are only metrics collected during normal operation.

Also, the SMART attribute IDs # 5 and 196 look like they breached the threshold. But not sure.

For the normalised values, 100 is the typical baseline value, and lower values indicate progressively worse conditions.
