Get information about Windows 2003 Server disk volumes with NTFSInfo

What's going on with your Windows Server 2003's NTFS volumes? Scott Lowe talks about Sysinternals' NTFSInfo utility, which can provide you with nearly everything you'd want to know about each and every one of your volumes.

How many of you are running something other than NTFS on your Windows Server 2003 servers? Probably not many—after all, in most cases, running a Windows server without NTFS doesn't make sense. But, how do you get granular information about your individual NTFS volumes, such as the number of sectors, cluster size, and other interesting NTFS information? Use Sysinternals' NTFSInfo utility, which you can download from Microsoft's Web site. (Sysinternals is now owned by Microsoft.)

Among other details, NTFSInfo provides you with the following information:

  • The cluster-based location of the Master File Table
  • The starting cluster of the mirror of the Master File Table
  • The size of the Master File Table
  • The size of the volume in megabytes
  • The total number of sectors and clusters
  • The free space available
  • The number of bytes per sector and cluster

After installing NTFSInfo, this is the output from one of the disks in my machine:
