Raxco's Perfect Disk gives lots of info.

I haven't used Win2k's defragger in ages. I assume it's acting similarly to the way PerfectDisk does as far as handling "system" areas.

I've got PD version 6.

NTFS has 3 areas that PerfectDisk has to defragment offline:

Defragmenting System Files & Directories

Certain files cannot be defragmented online due to operating system constraints. The constraints vary by operating system (Windows 2000 and Windows 2003/XP) and by file system format (FAT/FAT32 or NTFS). For a more detailed description see Offline files for your operating system). Generally the three types of files which may need to be defragmented offline are:

Pagefile - This is your virtual memory file (Pagefile.sys). This file is exclusively locked by the operating system and can only be placed by a boot time defragmentation pass.

System Files - These are operating system files such as the Master File Table, the hibernate file and other metadata files. Depending on the operating and file systems some of these files can be defragmented online and some offline.

Directories - On NTFS formatted drives directories are treated as online files. On FAT/FAT32 formatted drives directories are treated as offline files.

I'm assuming you're seeing the [link|http://support.microsoft.com/kb/174619|MFT] and/or the [link|http://www.ntfs.com/ntfs_optimization.htm|MFT (Expansion) Zone].

HTH a bit.

Cheers,
Scott.

I can see the MFT, it's right in the center of the disk where it belongs , all in one piece and is about the usual size. This big green lump is right at the beginning of the disk.

It also shows where your pagefile, hiberfile and MFT are.
