PeterBullivant 0 Report post Posted January 23, 2017 My Windows 10 Operating System and Programs are contained within 25GB of data on a separate 60GB HDD. Defraggler used to be able to defragment this HDD comfortably in less than 30 minutes; but now it is taking over 2 hours. I have been unable to identify any fundamental change in the data held on the file, nor any cause for the sudden increase in time required. Quote Share this post Link to post Share on other sites
