I bought a WD My Book 3.0 2TB USB 3.0.

When I power on the computer the external hd is turned on automatically.

Is it possible to leave the my book off when my computer turn on?

Thanks.

PS: I double posted in the mac section but since I use a PC I posted it also here, sorry for double posting.

it’s a shame that I cannot choose to leave my external hd off when I turn on the computers.

The external HD is noisy so why turn it on when I don’t need it? I use it only to backup my data and I don’t backup it every time.

So every time I power on my PC now I need to power off the external disk, this is really annoying.
