Hi Graham,

We've switched to hard drives that are powered by USB, so the external power supply is no longer needed.

Thanks

However, as is stated in the manuals...

If you are using a laptop and having power issues with the
external drive (isn't coming on, can't read directory, or
it sometimes fails or disappears) then check your laptop's
usb power settings.

An external adapter CAN be used 5V DC center tip +.


But as was stated this shouldn't be necessary. If you are
still having power issues to the external drive, be sure then
to plug the two usb pigtails into 'different' usb pairs.

Most usb connections come in pairs and the 5V you get from one
is the same 5V you get from the other. It is not in particular
the voltage gain that you are after, but the current draw.


A huge current draw will bring down your usb 5V to less than 5V,
however if you plug one pigtail into one usb pair and plug the
other pigtail into a 'different' usb pair, then you will be
drawing current from two different sources and the resulting
voltage to the external drive will be higher.
