    What's the difference between smart E1h and F1h attributes?

    dboreham

      I'm looking at a 710 drive, but the 320 seems to have the same attributes.

       

      The docs detail :

       

      E1h Host Writes
      The raw value of this attribute reports the
      total number of sectors written by the host
      system. The raw value is increased by 1 for
      every 65,536 sectors (32MB) written by
      the host.

       

      and

       

      F1h Total LBAs Written
      Counts sectors written by the host.

       

      But in practise the two counters return the same value (at least for me they do).

       

      Are there two distinct attributes for compatibility with certain smart utilities, or is there a real difference between these counters ?

       

      Thanks.
