New to StableBit DrivePool, how do I ensure drives will sleep when unused.  I have a basic setup and drives are not sleeping according to smartctl.  I do not have BitLocker enabled.  Note: this is something I want to validate before buying Windows 10 Pro Power Profile - Balanced -  has 5 min Drive Sleep enabled Drives are Internal SATA (5 x 8TB WD, 3 x 6TB WD)
