Everyone, I don't have an update but I might be able to help. I was using Defraggler to defragment target files, it was working normally. I then decided to further clean up my Windows 7 Pro (64-bit) PC by removing the Hiberfil.sys (using an administrative command prompt typing "powercfg.exe -h off"). I restarted Defraggler to analyse the new drive state and... no ability to analyse. I can find and defrag individual files, however. Strangely, all drives are not analysable, even separate physical disks. OK, even more information. After a second restart to install Windows Updates, it now works again. Maybe Windows system file management interacts with Defraggler in an odd way?

Running Defraggler on a 2.0 TB disk partitioned into a 250GB "C" and 1.8TB "D" disk. Defraggler runs fine on the C partition, but when the D partition is selected the "Analyze" and "Defrag" buttons instantly halt when clicked. Defraggler does not crash and another drive can be selected, at which point the program functions fine. Has anyone seen strange behavior in Defraggler for large disks/partitions? I have tested with the built-in defrag utility and it functions fine. I've also checked for file system errors and ensured that there is no pagefile on "D:" to no effect. Debug file is attached. Thanks! EDIT: The command-line version runs without any errors, but the tasks finish insanely quickly (full drive defrag in 30 seconds?). Not sure that it is accomplishing anything, and the /debug3 information is... very sparse. Defraggler.exe._1_14_159__2009_10_25_11_31_.txt Defraggler.exe._1_14_159__2009_10_25_11_31_.txt
