Hi, I have debian Squeeze installed on my machine. Computer is deployed with hard drive MAXTOR STM3320613AS. Recently, smartd have printed to logs the following messages: Feb 4 20:53:18 zsm-debian smartd[1868]: Device: /dev/sda [SAT], 3 Currently unreadable (pending) sectors Feb 4 20:53:18 zsm-debian smartd[1868]: Device: /dev/sda [SAT], 3 Offline uncorrectable sectors Feb 4 20:53:18 zsm-debian smartd[1868]: Device: /dev/sda [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 68 to 69 Feb 4 20:53:18 zsm-debian smartd[1868]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 32 to 31 After that I ran short selftests on given device, but they haven't found any error: # smartctl -l selftest /dev/sda smartctl 5.40 2010-07-12 r3124 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF READ SMART DATA SECTION === Raw_Read_Error_Rate, Seek_Error_Rate and

I have read that important pre-failing parameters are Raw_Read_Error_Rate, Seek_Error_Rate and Reallocated_Sector_Ct but still I can't decide whether disk is failing or not. Can somebody help, whether it is needed to replace disk or not? Any help is appreciated... Regards Matus Valo Raw_Read_Error_Rate, Seek_Error_Rate and
