I have a USB flash drive which is used for doing backups. I've noticed that when I do the backups, the access times for files and folders are getting updated.

Is there any way I can disable the atime/diratime options on USB flash drives? I'm assuming it would require a udev rule, since my USB flash drive is not specified in my /etc/fstab file.

Or would this be a moot point? I'm not sure if the Linux supports atime and diratime for FAT filesystems.

I'm using Ubuntu 16.04 with the LXDE desktop (so, Lubuntu).

  • You can specify noatime when mounting. Note that by default, modern Linux systems use relatime, which doesn't update the atime most of the times. To specify different settings, you need to pass an option to mount when mounting. How are your disks mounted? It seems you're using some automatic mount-on-insert, but which one? If you don't know, what distribution are you using and what desktop environment? – Gilles Jul 30 '16 at 22:31

  • What is diratime? Edit: found it wiki.archlinux.de/title/Noatime . – neverMind9 Mar 7 at 13:49
