Hello everybody, so i am thinking of getting a 1TB external hard drive this holiday season but i have had the problem before that if it is formatted in NTFS Mac's OS will read it but not write to it. And I was hoping that i could use the external between both Mac's and PC. My question is, will there be any trouble with the external hard drive if i format it to fat32 so that it can work with both Mac OS as well as PC OS, since it is 1TB in size?

FAT32 on a 1TB drive? The block size would be something like 15mb's per file lol(I think). It might be possible the largest I have partitioned in FAT32 was 160GB with fdisk that came with Win98se. But I think the limit is 2TB's MS doesn't even know and they are the one's that made it. They state that 127Gb's is the largest for win98 fdisk and 32Gb's for win2000 setup utility. Both are incorrect as I have personally formatted higher drives on both system utilities. Put simply, MS doesn't care to test the limits of FAT32 because it is a dead filesystem to them, doesn't matter if alot of people have to use it to retain compatibility, or choose it over NTFS because it has more tools available.

yes there will be a problem using fat32 with a 1TB hard drive. for the mac download the unoffical ntfs driver i think it's called NTFS3G from www.ntfs-3g.org
