[bcab] Re: The latest version of Diskkeeper is taking ages to defragment a 16GB hard drive, should it take this long?

Hi Alexander,

Bear in mind that I don't have specific experience of Disk keeper.

Defragmentation in general, though, can be affected by other processes running 
in the background on your system while the defrag is in progress.

Also, I am used to seeing the percentage increase rather than the opposite.  
i.e. One normally sees the percentage of the disk which has already been 
defragmented rather than the percentage still to be defragmented.  It is worth 
checking this point.

Sometimes, files are created or changed by background processes while the 
defrag is running which causes the defrag to return to the area on the disk 
where the file resides in order to defragment it and then continues again from 
that point.  This means that work already done by the defragmenter needs to be 
covered again from the point where the file was place in order to eliminate any 
gaps between files which may have been generated.

Where a file is changed periodically while the defrag is in progress, this can 
lead to an infinite loop in the defragmentation process.

I suggest that you check again to see if there are any programs running in the 
background which might possibly cause this effect.

Subject: [bcab] The latest version of Diskkeeper is taking ages to
defragment a 16GB hard drive, should it take this long?


Hi all,

As a result of discussions on the Access-uk list some months ago, I 
purchased  the program Diskkeeper to defragment my split hard drive on my 
Acer laptop.  I seem to be having problems setting Diskkeeper up to 
automatically defragment my C: partition which is the part that has the most 
files on it.

I tried setting Diskkeeper to defragment again today, and, even though I 
believe I set it to manual defragmentation rather than automatic, it seems 
to have only got from 35% to 32% after defragmenting for 3 or 4 hours, for 
the majority of which, I turned off my Supernova screen reading and 
magnification program.

My question is, does anyone know why this defragmentation is taking as long 
as it is?

Please note that I know defragmentation can take some lengthy periods, but I 
would have thought the chances were that with my hard drive being split in 
two, defragmenting would get to lower than 32% in the time I have had it 
running.

Thank you all in advance for your answers  to my question, and any advice 
you can give me on this issue.
