2^64-1 clusters

These values where shamelessly copied from Russel's link
256 terabytes minus one cluster (64 kilobyte.)

You need to subtract 64 kilobytes. So you are close, but no cigar!

Smile Re: NTFS help

If I want to know the bigest Hard Drive that FAT 32 can support
32 X 268,435,455 = 2. TB

But if I want to know the Bigest Hard Drive NTFS can support you say take Cluster size and Subtracked it from Hard Drive 256 TB

Why would I not do the Math like I do with FAT 32 64 k X Number of Clusters???????

2 to the 64th clusters (clusters being 64K each) is 256 terabytes. Then, according to the wiki link I posted, you must subtract one cluster from that.

Did you read the Wiki page?

[Edit]

2^64 X 64K - 64K

Two to the sixty fourth times sixty four thousand minus 64 thousand.

2^64 is the number of clusters.

64K is the size of each cluster.
