Unlike Windows NT, when you specify that install should format a partition as NTFS, it does so directly, without the
need to CONVERT the partition. Windows NT converted the partition using a cluster size (Allocation Unit) of 512 bytes.
When Windows 2000 formats a NTFS partition, the following cluster sizes default:
Drive Size Cluster Size Number of Sectors
--------------------- ---------------- -----------------
512MB or less 512 bytes 1
513MB to 1024MB(1GB) 1024 bytes (1KB) 2
1025MB to 2048MB(2GB) 2048 bytes (2KB) 4
2049MB and larger 4096 bytes (4KB) 8
NOTE You can alter the cluster size used to format a drive in
Disk Management and with the
/a: option of the FORMAT
command.
