What does the output of this look like on your drives?
smartctl -a /dev/sdb | grep Load_Cycle_Count
193 Load_Cycle_Count 0x0032 001 001 000 Old_age Always - 1284384 So if that's not lying (and SMART data is often false) then the drive would have spun down an average of about 30 times per hour during the life of the system. I've just tried "hdparm -S0 /dev/sdb" but that hasn't stopped the Load Cycle Count from increasing. So it seems that your claims are correct. I guess that my WD Green drive is just quiet enough that it can spin down and up without me noticing. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
