(until they go bad)
But why use NTFS or FAT32 when you are running an Apple OS?
And if I were to exchange with 7, well FAT32 is OK till I need to move some 4GB file or I discover that it's not a reliable file system (which could have us write that all drives with FAT12 to FAT32 are "bad".)
And then we have that issue with NTFS where some Apples can't write to such without a little help. Again, some folk would say that's bad too.
Sorry, I have no good news here. But we seem to muddle along.
