Why won't STOP button work? in Defraggler Discussion Posted December 18, 2016 · Report reply Hi Moderator Dennis, I don't see the 2 topics as being the same, the only way I'm able to stop Defraggler is reboot my computer, I've tried all other methods. Now I need to know if the program is even working, it isn't just one file, I've had problems for the past 24 hours trying to get my slave drive degragged. Defraggler absolutely will not complete any process on my whole drive (size info below), Quick Defrag, Full Defrag, I think "Benchmark" may have worked once yesterday, but won't now. It says the disk health is Good. I'm thinking I'll need to buy a program to do this, but not sure, may have to take it i to a shop. Since the drive is so fragmented, do I have to do it a folder at a time? Even then, the one I wrote about below didn't seem to process, though it said defragmenting 2% after a LONG time of running. I don't have a lot of $ to take it in to a shop if I can just get it defragged somehow. Thank you so much! p.s. I just reinstalled defraggler. Here is what I wrote: In Defraggler's world, is a 45mb tif file large? I'm a print designer and have a LOT of files that size. Is there a way anyone could give me a very rough time to defrag that file? A tech suggested I didn't need to defrag "these days" so I turned it off about 5 months ago. I was able to defrag my Boot drive yesterday, but have been having a beastly time with my slave drive. It's 1 TB, with 274 GB free space. I feel like I'm making very little progress, and I'm a patient person. I can defrag individual folders on it where there is very little content, but it's been stuck in a 1.13 GB folder doing one 45 mb file, for a very long time (likely about an hour, but didn't look when I started it). Am I just expecting too much from the program? Your Help is vastly appreciated!!
