It might - the switch on the disk enclosure might depend on the switcher
already being powered up; if it were left on, and the power supply switched,
the drive _might_ not be able to handle the power-on transients from the
power supply.
Use the switch on the drive box to power up/down the drive, and the switch
on the power strip to save energy. Turn on the power strip first, then
the drive box switch, and when turning it off, turn off the drive box switch
first, then the power strip.
