I do not believe Hermes 222 prevents hdd spin-down.
Not without the utility to disable sleep mode.And there is any solution available to me to prevent my HD from going to sleep?
It could be either one to tell the drive to spin-down.Another question whatever tells the HD to go to SLEEP is it in the firmware of the actual drive? or is it located in the board of the external drive? (SATA/IDE to USB Board)
