Hello, I'm monitoring a Linux Software RAID1 (i.e. mirrored) pair of (new) drives. One drive (#2) has 100 reallocated sectors in its first 1000 hours of operation, whereas drive #1 still has 0. Both same amount of operational hours in the same enclosure. Should I be worried? When do manufacturers grant replacement (any experiences there, or should I wait until the count reaches 1000?) Its temperature is 5 degrees Celcius higher (throughout operation) than drive #1, its soft read error rate and hardware ECC recovered rate are both af factor of then higher then drive #1. Drive report SMART status to be healthy, no errors on short and long tests. Best regards, Leon Woestenberg. |

When do manufacturers grant replacement (any > experiences there, or should I wait until the count reaches 1000?) I'd watch it. If the reallocated count continues to climb, you should see the normalized attribute value approaching it's failure threshold. At that point you may want to call the vendor. But you disk may have tens of thousands of spare sectors. Until the Attribute fails or gets close to failure, you don't know. > Its temperature is 5 degrees Celcius higher (throughout operation) > than drive #1, its soft read error rate and hardware ECC recovered > rate are both af factor of then higher then drive #1. Keep an eye on it. > Drive report SMART status to be healthy, no errors on short and long tests. At this point, I'd just monitor it. Once the bad sectors have been reallocated it may settle down to a long and happy life. Bruce |

It was at a normalized 241 (out of 255) with a threshold of 41. > At this point, I'd just monitor it.

Time to enable the mail feature of smartmontools. :-) Regards, Leon. |
