It seems SMART output is incorrect for many fields. Temperature swings from
negative to positive in hundreds. Raw value for 165 Total_Write/Erase_Count
was 2054 before short selftest and becomes 4 afterwards. Raw value for 234
Perc_Write/Erase_Ct_BC is 10000. 232 Perc_Avail_Resrvd_Space shows failing
now. There is no selftest log although selftest is supported. smartctl -o on
has no effect, like CZ80 I have.
Attached is the output of smartctl -x. I am not on the mailing list, if
further information is needed, please CC me.
