The Convert.exe Tool Uses 512-Byte Clusters (231756)


The information in this article applies to:

  • Microsoft Windows NT Workstation 4.0
  • Microsoft Windows NT Server 4.0
This article was previously published under Q231756

SYMPTOMS

When you use the Convert.exe tool to convert a partition from a FAT file system to an NTFS file system, the NTFS partition uses 512-byte clusters.

CAUSE

This behavior is by design.

MORE INFORMATION

The Convert.exe tool uses the default cluster size of 512 bytes. Using a smaller cluster size allows more efficient use of space on the hard disk and greater probability that the Convert.exe tool has sufficient disk space to perform the conversion.

To change the cluster size, use the /a switch with the Format utility to specify the desired cluster size. For information about default cluster sizes, please see the following article in the Microsoft Knowledge Base:
