Brotoles

I thought that too, but I have 2 identical drives, and the other one also has a GPT, but I made two partitons, one with 1,81TB (for games) and the other with 931 MB (for temp stuff), and when I defrag them, even though they also have 512 bytes sectors, they defrag at a much faster speed. I thought it could be because the 3TB (2.72TB actually) partition is the only one that I defrag using the option to move big files to the end of the drive, so I disabled this option and the drive still defragments very slowly. When I deleted some big files, I tried defraging the drive again, and it defraged the big files in a sec, and got stuck when defraging the small ones... Even cancelling the defrag operation takes longer than the other drive with 2 smaller partitions, as if the program were a little "lost"....

Bump this topic, I'm having the same issue....I even thought it was a defective sector, but it isn't. I did an HDDScan on the entire drive and it didn't return any errors. I'm running the latest version of Defraggler (2.18). I'm running a full defrag, moving big files to the end of the drive. The big files were moved really fast, but when Defraggler started moving the small files, it got reeeeeally slow (the files themselves were moved really fast, but the program only moved 2-3 files per second, just as it happened to PlaysGames11). Even though I don't enable system restore on this drive, I also tried disabling VSS just to be sure, but it didn't make any difference :-( The drive is a 3TB Seagate Barracuda 7200 rpm that I use to store my media files and backups, It has a GUID partition table, and a single NTFS partition (since it uses GPT, it has 512 bytes sectors instead of 4kb ones, don't know if this could be an issue). The defrag runs with normal priority, and the CPU usage hovers around 13% all the time, even when there's almost no disk activity, although I have a beefy CPU (Core i7 4790) Edit: The drive has 733,5GB (26%) free space, so this shouldn't be an issue... My System Specs: CPU: Intel Core i7 4790 Motherboard: Gigabyte Z97X-UD5H GPU: Gigabyte GTX 670 WindForce OC RAM: G.Skill 16GB (4GBx4) DDR3-1866 PSU: Corsair AX760 OS:Windows 7 Ultimate x64 Storage: Samsung SSD 840 Pro 256GB (System Drive) 2 x Seagate Barracuda 3TB drives (no RAID) One DVD drive and one Blu-Ray drive, both from LG Everything with the latest official drivers and firmwares, no overclocks, and Windows is fully updated too. The drives are running in AHCI mode, and I've installed Intel Rapid Storage v13.0.3.1001. I really like Defraggler, of all the free defragmentation programs that I tested, it's the most feature rich, but this slowness is starting to turn me away from it :-( English is not my native language either, so I hope I was clear enough, and gave relevant information. I also really hope you guys can solve this :-) Thank you so much for your patience, my best regards, Lucas
