I am looking for some external hard drives for Time Machine, but most of the manufacturers would sell the Mac-ready hard drives for a higher price than Windows ones. Some are Mac and Windows compatible. Will the Mac and Windows compatible hard drives work with Time Machine? Right now, I am looking at the following hard drives... 1) Western Digital My Passport Elite 2) Western Digital My Passport Studio (Mac-Ready, but more expensive) 3) Maxtor OneTouch 4 Mini 4) Seagate FreeAgent Go (Windows Version) and some other ones. Do you have some recommendations? Will any of these work with Time Machine besides the Mac ready one? Thanks! Right now, I am more at looking at the Seagate FreeAgent Go (Windows Version). Will it work for OS X Leopard and Time Machine?
