sysinternals NTFSInfo Description

NTFSInfo is a little applet that shows you information about NTFS volumes. Its dump includes the size of a drive's allocation units, where key NTFS files are located, and the sizes of the NTFS metadata files on the volume. This information is typically of little more than curiosity value, but NTFSInfo does show some interesting things. For example, you've probably heard about the NTFS equivalent of the FAT file system's File Allocation Table. Its called the Master File Table (MFT), and it is made up of constant sized records that describe the location of all the files and directories on the drive. What's surprising about the MFT is that it is managed as a file, just like any other. NTFSInfo will show you where on the disk (in terms of clusters) the MFT is located and how large it is, in addition to specifying how large the volume's clusters and MFT records are. In order to protect the MFT from fragmentation, NTFS reserves a portion of the disk around the MFT that it will not allocate to other files unless disk space runs low. This area is known as the MFT-Zone and NTFSInfo will tell you where on the disk the MFT-Zone is located and what percentage of the drive is reserved for it.
