This is my workstation
Does the power management "work" on your 5805?
I created a test four disk raid 5 array comprising four seagate 1TB 7200.12 drives.
Array was set to spin down after 5mins
It didn't
The 5805 was running the lastest firmware, latest ASM and latest driver
OS was win 7 pro
The power management feature of the 5805 made the card very attractive, as it would (could) power down the array when not is use (much of the time)
Comments????
