Joe L. Posted May 11, 2011 Share Posted May 11, 2011 It indicates your disk/disk controller does not support the IO command to spin down the drives. (errno = 22 = invalid argument) ATA_OP_STANDBYNOW1 is not supported with your specific hardware with the drivers in 5.0beta6a. You can do nothing to prevent the errors other than turn off the spin-down feature built into unRAID and instead use hdparm commands to set the disk's internal hardware spin-down timers.
