    I want to get an external, portable HDD to use with a 2009 MacBook, which only has USB 2.0 ports.

    Will a USB3.0 drive work straight out of the box (albeit with slower data transfer) or will I have to install drivers, update OSX, use 2 USB sockets to power it, wave a dead chicken over it, etc..? Anyone have any experiences to share?

    I'd get a USB 2.0 drive, but they're now hard to find, or oddly more expensive. So, the two USB 3.0 drives I'm currently considering are:

    Lacie Rikiki USB 3.0, 1TB

    Seagate BackUp Plus, USB 3.0, 1TB

    I am nearly positive that all USB 3.0 devices are backward compatible to USB 2,0 ports. No drivers necessary. Or dead chickens. :D

    Thanks Wildcard.

    I'd like to be 100% sure before I splash the cash, is anyone please able to offer any cast iron proof USB3.0 HHD will work with no dramer through USB2.0 ports?

    I have 2 usb 3.0 external drives that runs fine on both usb 2.0 and usb 3.0. I use the drives for backups and switch from a 2008 iMac to a 2013 retina MBP to a 2011 13" MBP

    There have been some reports of problems with usb 3.0 on usb 2.0 connections, but I expect the issues have been resolved by now.
