Even though you have a total of 28% free space available on the partition, all of that free space may not be usable by defragmenters as Microsoft's defrag APIs don't let defragmenters use the free space INSIDE of the MFT Reserved Zone. Diskeeper strongly recommends that you have at least 25-20% usable free space in order to effectively defragment. Anything less than that it Diskeeper can exhibit the behavior that you are seeing.
In all fairness, Diskeeper V7 has been out since last fall and does a little better job than Diskeeper V6.
"I have tried Perfect Disk, but didnt find it to my liking." If you don't mind me asking, what didn't you like about PerfectDisk?
It seemed slower, and had squares that showed the progression, like the defragmenter that comes with windows 98/me. It also arranged the data a way I didnt like, if I understood correctly, the most used at start of drive and the less use later on the drive. The colors was also a miss, it was hard to see how files where fragmented or not fragmented.
I dont know its a long time since I used it and my memory is no good, but the whole application with the menu at the left i didnt like either. I might try it again a second time and see if I have "grown" on it. it has happened before...
Well my friend has a lot of space available, but can never defrag the HD. He's pagefile is very fragmented too, but for a boot-time defrag doesn't he need at least diskeeper 6? I heard diskeeper 5 messes up on a boot time or MFT defragmentation. Does speedisk defragment the pagefile online?
