Using smartctl to detect "scan errors" (like google tells me to do ...)
The big report that google published made it clear that even a single "scan error" in the SMART data of a disk drive is a good predictor of eventual failure... However, when I run smartctl: # smartctl -a /dev/da0 | grep -i pre-fail 1 Raw_Read_Error_Rate 0x000b 100 100 016Pre-fail Always - 0 2 Throughput_Performance 0x0005 135 135 054Pre-fail Offline - 84 3 Spin_Up_Time0x0007 126 126 024Pre-fail Always - 612 (Average 612) 5 Reallocated_Sector_Ct 0x0033 100 100 005Pre-fail Always - 0 7 Seek_Error_Rate 0x000b 100 100 067Pre-fail Always - 0 8 Seek_Time_Performance 0x0005 123 123 020Pre-fail Offline - 31 10 Spin_Retry_Count0x0013 100 100 060Pre-fail Always - 0 There is nothing called a "scan error". Further, the wikipedia page for S.M.A.R.T. has nothing in the error table called a "scan error". So ... What is a scan error, and which metric should I tell smartctl to check ?
