WD External USB HDD’s do Spin Down
Wednesday, October 8th, 2008I’ve been trying to reduce the power of my Home Server and Media Centre. Since my Power Meter debacle, I am now re-testing all the equipment and getting some rude shocks.
One of the positives out of this is that my 1TB Western Digital My Book Essential and 300GB Western Digital My Passport Essential both spin down and save power. On USB, this is a nice feature, as many of the generic external cages don’t spin the drive down.
The WD’s spin down on XP, Vista and Windows Home Server which is based on Server 2003. The timeout appears to be independent of the OS settings.
