This is your wake up call I believe. </blockquote> </div> That's a good result, not bad; those number count downwards.. that's why the threshold is lower than the current or worst value. See the manual page for smartctl for more information on interpreting the output of the tool: "Each Attribute also has a Threshold value (whose range is 0 to 255) which is printed under the heading "THRESH". If the Nor- malized value is less than or equal to the Threshold value, then the Attribute is said to have failed. If the Attribute is a pre-failure Attribute, then disk failure is imminent." </blockquote><div> Not reallocated sectors. I new disk has "zero" reallocated sectors. </div></div> SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 109 093 006 Pre-fail Always - 198961952 3 Spin_Up_Time 0x0003 093 093 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 9 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0 7 Seek_Error_Rate 0x000f 076 060 030 Pre-fail Always - 45261344 9 Power_On_Hours 0x0032 099 099 000 Old_age Always - 964 -- Paulo Roma Cavalcanti LCG - UFRJ
