Looking to replace my aging Western Digital 1TB external with something a little less old to serve as my primary data back up device. Tried a Seagate a couple years ago but it had a lot of issues with the power supply and even after warranty replacement it still didn't work. Definitely budget conscience and need at least 1TB capacity but more is always better. Just a little confused due to the wide variety of HD's on the market now, but pretty tempted just to look for a good deal on some WD brand external. Does anybody know if there are any that are cross compatible between Mac and Windows laptops these days?
