When u're talking about NT do u mean FAT or NTFS?

The default cluster sizes for FAT are as follows (copy&paste from http://www.winntmag.com/Articles/Index.cfm?ArticleID=3675) :

Partition Sectors per Cluster Cluster Size

<32MB 1 512 bytes
<64MB 2 1KB
<128MB 4 2KB
<255MB 8 4KB
<511MB 16 8KB
<1023MB 32 16KB
<2047MB 64 32KB
<4095MB 128 64KB

The defaut cluster sizes for NTFS are as follows (copy&paste again) :

Partition Sectors per Cluster Cluster Size

<512MB 1 512 bytes
<1024MB 2 1KB
<2048MB 4 2KB
<4096MB 8 4KB
<8192MB 16 8KB
<16,384MB 32 16KB
<32,768MB 64 32KB

>32,768MB 128 64KB

Of course one could specify different cluster size for NTFS when formatting the volume and the only way to get some info about the cluster size I am aware of is running :

chkdsk VOLUME: /I /C

... for the volume of interest and looking at the result for something like:

     XXX bytes in each allocation unit.
   YYY total allocation units on disk.
    ZZZ allocation units available on disk.

hth,
