I just came back from Costco and picked up a FreeAgent Go 250GB portable hard drive to back up my MBP for the first time. I just noticed, however, that the box doesn't mention anything about Mac OS X compatibility; just Windows XP/Vista. And a closer look at Seagate's website reveals that they sell two versions of the FreeAgent Go: a Mac and a PC version. As Costco is quite a drive away, am I better off opening it up and giving it a try (do you think it'll be compatible with Time Machine?) or just return it for a different hard drive? I really should've paid closer attention to the compatibility labeling (or lack thereof)... I suspect it should be okay, but better safe than sorry I guess. Thanks.
