    Abnormal device statistics on a brand new SSD 530

    mhtsai

      Hi All,

       

      I just bought a new 120GB SSD 530 yesterday (SSDSC2BW120A4K5, orignal retail package), but the device statistics reported by smartctl seems abnormal:

       

      The SMART values show that the drive was never used -- most are zeros, but some Device Statistics fields are not zero. For example, the "Logical Sectors Written" is 18343505 (8956MiB), and "Logical Sectors Read" is 16762989 (8185MiB), which are not sync with zeroed SMART "Host_Writes_32MiB", "Host_Reads_32MiB". The "Power-on Hours" field also has the same problem.

       

      Does that mean that the drive wasn't correctly reset before shipping? firmware bug? or other issues?

       

      Thanks.

       

       

      The following are smartctl outputs

      $ smartctl -x /dev/sdc
