It's my understanding that this number should be around 55... most of the other counters are within normal ranges... it's somewhat confusing... any ideas?" |

| I too was confused by this, until I read somewhere that the percentage shown must be divided by the number of spindles (drives) in the array. So if you have 10 drives in the array, the actual use is 50-70%. |
