I also tried through the command prompt and when i reached the cluster sizing, i put 512 and i t said smth like this: The cluster size has to be a multiplication of 4068kb for this drive.
PS: Im portuguese so in english, its probably not like this but it means the same.
There could be 2 reasons for this - one, you could have an Advanced Format disk (AF) where you cannot have cluster sizes smaller than 4K. The second could be that the partition size doesn't allow cluster sizes smaller than 4K (which is more likely the issue, although AF drives are becoming more common in smaller sizes).
The real question is, though, why you'd want cluster sizes smaller than 4K? Assuming you're formatting the partition with the NTFS filesystem, the OS ntfs.sys driver was really designed to operate on volumes with cluster sizes of 4K and larger for large volumes, so you'd likely take a perf hit with smaller cluster sizes (unless the partition was sufficiently small - smaller than 1GB, for instance).
i wanted that so i could store the biggest amount possible but i guess it wont make much difference...
Btw, what is that AF disk and if i have it, can i turn it off? the partition has 265gb and the disk is 500gb.
