I would take this as a serious warning. Time to get the disk replaced in a nice, calm, unrushed manner. The disk is *likely* to hard fail within a year. Do NOT think "I can leave it 9 months", that 1 year is not an accurate prediction. Questions: • how much is your data worth ? • what will it cost your time to have to suddenly rebuild the machine (prolly at the most awkward time) ? Compare these costs to the price of a new disk. > I ran "smartctl -t offline /dev/sda", and the eventual result of "smartctl > -a /dev/sda" shows > > SMART Attributes Data Structure revision number: 16 > Vendor Specific SMART Attributes with Thresholds: > ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE > UPDATED WHEN_FAILED RAW_VALUE > 1 Raw_Read_Error_Rate 0x000b 100 100 016 Pre-fail > Always - 0 > 2 Throughput_Performance 0x0005 140 140 054 Pre-fail > Offline - 68 > 3 Spin_Up_Time 0x0007 178 178 024 Pre-fail > Always - 351 (Average 293) > 4 Start_Stop_Count 0x0012 100 100 000 Old_age > Always - 120 > 5 Reallocated_Sector_Ct 0x0033 100 100 005 Pre-fail > Always - 0 > 7 Seek_Error_Rate 0x000b 100 100 067 Pre-fail > Always - 0 > 8 Seek_Time_Performance 0x0005 124 124 020 Pre-fail > Offline - 33 > 9 Power_On_Hours 0x0012 088 088 000 Old_age > Always - 85831 > 10 Spin_Retry_Count 0x0013 100 100 060 Pre-fail > Always - 0 > 12 Power_Cycle_Count 0x0032 100 100 000 Old_age > Always - 120 > 192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age > Always - 1028 > 193 Load_Cycle_Count 0x0012 100 100 000 Old_age > Always - 1028 > 194 Temperature_Celsius 0x0002 171 171 000 Old_age > Always - 35 (Min/Max 21/43) > 196 Reallocated_Event_Count 0x0032 100 100 000 Old_age > Always - 0 > 197 Current_Pending_Sector 0x0022 100 100 000 Old_age > Always - 0 > 198 Offline_Uncorrectable 0x0008 100 100 000 Old_age > Offline - 0 > 199 UDMA_CRC_Error_Count 0x000a 200 200 000 Old_age > Always - 0 > > SMART Error Log Version: 1 > No Errors Logged > > > which seems to indicate no problems. > > I admit I'm not a smartctl wizard, but to me it seems that smartctl is > contradicting itself. > > Can anyone help me out? -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.
