Moreover the NTFS driver also try to leave some buffer around files like ext4 to avoid fragmentation. And since Vista Windows always try to run defragmentor automatically | |

| Jun 11, 2018 at 9:03 | comment | added | Gizmo | @Vimos that will indeed be another reason, just let it finish. See superuser.com/a/1208334/239433 | |

@Gizmo I find an interesting thing, when the noise is loud, ext4lazyinit process is running, could this be another reason?

| Jun 8, 2018 at 10:37 | comment | added | Gizmo | @C0deDaedalus also I would like to add that the disk in theory, is in fact, fragmented, but individual files aren't and future files probably will not either, because each grouped data is spread far from other grouped data. This is the case which I'm describing for "smart" file systems. | |

@Vimos don't quote me on it but by looking at kernel.org/doc/Documentation/filesystems/ext4.txt , the mb_max_to_scan and mb_min_to_scan parameters would be something that look like they do that. I'm no expert in this field so be careful. I would set min to 0 and max to something much smaller than your current system has (10x lower or 100x lower).

| Jun 8, 2018 at 8:00 | comment | added | Vimos | Is there any parameter to control how far apart? There should be a threshold for a specific brand and size, if the space is large than the threshold, noise will be unavoidable. | |
| Jun 8, 2018 at 7:31 | comment | added | C0deDaedalus | Hmmmmm. I got it - smart filesystem B-) | |
| Jun 8, 2018 at 7:24 | comment | added | Gizmo | @C0deDaedalus that would be applicable to Windows (or specifically NTFS, FAT32, FAT16, etc.. smart filesystems don't have this problem as often, as in my own experience, a file server that I used to manage on Windows server had 99% fragmentation and performance was a disaster). But the smart file systems do make the heads move around a lot which can make you think that your disk is fragmented, but it's not the case. | |
