I tried buying a Seagate HD yesterday but apparently, its not compatible with my MBA. I love Seagate because of its sleek design and affordable price. Does Seagate make an HD just for MAC? What other brands can you recommend?
Seagate USB drives work just fine on Mac. As stated, it needs to be formatted to HFS for Mac, or to FAT if you want to use it on Windoze and Mac without messing with drivers.
exFat. FAT has a 4GB partition size limit. FAT32 has a 2TB limit. exFAT is newer and better if you are using Vista or higher.
Oops, I presumed the OP would use his MBA to format. Yes, exFAT, the last option listed, not [MS-DOS]FAT for cross-platform compatibility.
