However, not all EIDE hard-disk drives support this feature. Enabling this feature for drives that do not
support it may cause the EIDE drive to become inoperable until the computer is restarted and the
Power Management option is disabled.
In low-power mode, the disks inside the drive stop spinning. They remain idle until the next drive access,
which causes them to start spinning again. (Because the disks take a few seconds to regain full speed, you
may notice a slight delay when you next access the hard-disk drive.)
When Power Management is set to Disabled (the default), the disks spin constantly as long as the system is
turned on.
