Switch on by Using the Terminal Strip vs. Using the Switch o

[Joe]

I recently got an external hard drive, an OWC Mercury AL-Pro. It has an
external power supply - from the size of it, I thinks it's a switch-mode.

The only power switch is on the hard drive enclosure itself, not on the
power supply.

I have the thing plugged into a terminal strip that has individual
switches for each outlet.

Does it make any difference to use the switch on the terminal strip for
the on-off switch and leave the switch on the enclosure always on?

I'm thinking that maybe the switching power supply might put out a pulse
at turn-on, and so it might be better to have the switch on the
enclosure off until after the power supply has been turned on.

Thanks.

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.

Cheers!
