Hi Alexander, You have folks on this list with direct experience of disk keeper namely, Tom and Steve, therefore I defer to their specific knowledge of the product. I may, though, be able to clarify one point. The discrepancy which you see in the disk space figures may be due to the calculation of kb and gb. There are 1024 bytes in a kilobyte and 1024 kilobytes in a megabyte. If, therefore, you look at a number of bytes or kilobytes, you are seeing a multiple of 1024 rather than simply 1000. This convention is normally only broken by disk manufacturers who usually specify their hard disk capacity in multiples of 1000.

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.

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.
