When attempting to analyze or defrag my drive using Defraggler, when analysis is complete it immediately says defrag is complete as well, and reports 0% Fragmentation. However, in that pretty display of red and blue blocks, my drive is mostly red blocks, and Windows Defrag reports that its 25% Fragmented. Defraggler will properly report and fix all other drives in and attached to my system, just not the C: Any help in resolving this issue would be greatly appreciated, and if there's any information I can give to make the issue easier to solve, please let me know. Thanks in advance!
