Hey, today I used Defraggler for the first time, and I'm very dissapointed. I analyzed my C drive , and it said it was 50% fragmented. So I clicked 'defragment' (not the quick version). At the start, I checked it every now and then, and it seemed to do well, so I let it run a few hours. After about 3 hours, I came back, and saw it was done defragmenting. But when I then analyzed the drive, it was 45% defragmented! It took hours to defragment 5% of my C drive, and then randomly stopped. I thought maybe I'm unlucky this time, and clicked 'defragment' again. This time, I watched the % fragmentation and the amount of fragmented files closely. After 10 minutes, it said it was 40% done with defragmenting, but the amount of fragmented files was exactly the same as before. Then I clicked 'stop' , followed by 'analyze'. To my surprise, it now said the drive was 54% fragmented!!!! Defraggler not only failed at actually defragmenting, it even (according to the program itself) fragmented some more files. Oh for if you want to know, here's my system:
Acer Aspire 6930G
Intel Core 2 Duo processor T5900
2x 320 GB 5400 RPM hard drives
4 GB DDR2 RAM
GeForce 9600M graphics card
I deinstalled and won't be using it again, but still hope you can fix this for future users, right now they're better off without the program.
