Hi guys, a friend just offered me a Lacie Quadra D2 (Firewire 800,400, esata and usb2.0), we wants it HDD back so I need to put there a new one. The HDD that comes with it is this Hitachi Deskstar: I tried to replace it with my Samsung HD502J 500Gb and the disk doesn't start spinning. Tried an old Western 160Gb and the same.Both HDDs go fine in another enclosure. The Lacie works fine with the Hitachi. One thing that I noticed: Hitachi: 12V - 670mA 5v 360mA Samsung: 12V - 500mA 5V - 700mA Do I need to find an HDD with the same amperage @5v of the Hitachi? I can't seem to find one... And the strange thing is that lots of people said that for example Western green drives are ok (and they are rated for: 5v:0.7A 12v:055A). Any idea?
