When the defragmenter has defragged all the files it can, it proceeds to do
'compacting files..' but stops well before all the 'whitespace' has defragged. If the defragmenter is run consecutively repeatedly, will it eventually complete the compacting (i.e. defrag all the 'whitespace') ? Jim Hawkins |

Open Disk Defragmenter and click on Analyse. Select View Report and click on Save As and Save. Now find VolumeC.txt in your My Documents Folder and post a copy. Do this before running Disk Defragmenter as it is more informative. -- Hope this helps.

White areas on an NTFS volume might also represent the MFT zone. -- d-d |

XP defragmenter doesn't defrag empty disk space.

Yeah, the built-in XP defragmenter is not very good at consolidating free space, that's why you see a lot of white areas after a XP defrag. That said, there is limited benefit in full free space consolidation because if the 'compacted' files are modified, you're going to have fragmentation again because the files have no space to grow. Consolidation of free space into a few 'chunks' is about as beneficial as it would be in terms of resources-expended-to-benefit-obtained ratio, IMHO. -- sareth |

No. But I find that if the defragmenter is run from an OS on another HD, the defragmenting goes a little further than if the defragmenter was defragging its own HD. After 2 or 3 runs, though, the files are about as compact as the defragger can get them - which is fine, since if the only empty space were far from the files being edited, the read/write head would have to travel farther from the bulk of the file to get to the resulting fragments. *TimDaniels* |
