What I ment is this.

The Bigest Clust Size win xp can have is 64 kB
So if you want to know the Bigest Hard Drive you can use you take 64 kB X the amount of Clusters it can support.

But I did not see how many Cluster NTFS can see???????????

2^64 clusters...

If my maths is correct, which it proberbly isnt, then it can theoretically recognize around

1125899906842623.99993896484375 GB

.... I would worry about it.

This is what I sould have asked and how I sould have asked it.

If you want to know the Largest Hard Drive Size FAT 16 can support
You take the Largest Cluster Size it can have 32 kB X the Maximum Numbers of Clusters it can support 65,536

32 X 65,536 = 2. GB = 2. GB and you have 2. GB Hard Drive.

Now If you want to know the Largest Hard Drive NTFS can support you would do the same.
Take the Largest Cluster Size it can have 64 kB X the Maximum Numer of Clusters it can support witch is way to many RIGHT.

So how do you do the math for ntfs?????
