I am a fairly new to Defraggler. Since it has a good reputation, I presume I must be missing something.
I have been bothered by the fact that I can turn Defraggler loose on the disk with 2% or 3% fragmentation (by Defraggler's own measurement) and it takes a very long time -- literally days -- to defragment. During that time, it makes the disk 25% - 50% fragmented as it works -- that seems excessive. It also creates a heavy enough load on the computer, even when set to low priority, that it is a problem.
The second, and arguably more important, problem is that when it is done, it reports 1% fragmentation (understandable) but its disk diagram shows a lot of brick-colored squares.
In my most recent run, it conformed to the above description. When done it said:
99 Fragmented Files (1.1GB)
271 Total Fragments
1% Fragmentation
Sounds good, but since there were a lot of brick colored squares, I immediately pushed the "Analyze" button. It gave figures more in line with all those brick-colored squares:
1,286 Fragmented Files (83.6GB)
19,582 Total Fragments
52% Fragmentation
Just to get some confirmation, I brought up the default Microsoft defragmenter and had it analyze the disk. Basically, it agrees with Defraggler's analysis. It shows a lot of fragmented space. Its report says:
1,289 Total fragmented files
18,344 Total excess fragments
51% File Fragmentation
The only explanation I can see is that there are three very large files on the disk -- they are compressed disk backup images of 38, 42, and
43GB. According to Defraggler's diagram, virtually all of the fragmentation is in these files (even though they were not fragmented to begin with). It appear that at least most of the fragmentation is in just two of the three files.

My setup is:
Defraggler version V2.00.230
Pentium 4, 3GHz, with 3GB RAM -- not the most modern, but should be quite adequate About 1.3GB RAM in use.
Windows XP Pro, SP3, all patches installed
My disk is nowhere near full. Defraggler reports I have 160.7GB used,
and 537.9GB free, so Defraggler has lots of room to work.

What I read is that Defraggler works well, and runs quickly. My experience is that it fragments my disk a lot, takes days to do so, and loads the computer a lot while doing that.
OK -- any suggestions on what the problem might be before I uninstall Defraggler as non-functional?
Thanks,
