Ok. Cool. I've found for the most part NTFS to be quite reliable over the time I used.

The only time I did have problems with it was (I think) when I had created lots (many thousands) of hard links using rsync to create multiple image backups. If the file didn't change rsync created a hard link to the last backup which might have been a hard link to the backup before that and so on. It was corrupting the Master File Table somehow and the whole thing fell over. I guess that makes it not the best thing then

But yeah exFAT is probably the best option otherwise. Seems there's a patent issue with Linux according to Wikipedia though.

However won't the underlying problem still remain? Isn't it the controller that's fundamentally broken accessing the large drive?
