After defragging a 320 Gb 2,5" drive with an os on it through another computer, since it left some red squares (so it didn't defragged the whole drive) I decided to switch on the "Move large files to end of drive during whole drive defrag" and re-defrag the drive.
So it started and after a while it reached 75%, and after clicking one of the red squares it listed what files and folders belonged to it, and by mistake I clicked on one of the column top side, that switched the order by that column, so to block the mistake I tried to close the file list tab, but then Defraggler stuck and/or froze, not responding at any command (but on task manager I see it still working or doing something).
Actually I didn't kill the task since it was defragging and I'm afraid it would mess with the data on the disk. So, since I have an i7 920 (quad core hyperthreading, on 6 gb ram) I set Defraggler to use 4 logical CPUs while all the other tasks to the other 4, where possible, and I also rised its priority to "High" (I also tried "Real time" but it seems to rise all the cores, real and virtuals, to high usage).
I hope it would unstuck itself after ending doing what is supposed to do, but after several hours it seems to keep stuck.
Any help, please?
