Hello all,
I've been having some trouble with USB drives in the last few months. When
copying files onto a device, the copy appears to be instantaneous, but is
clearly buffered by the kernel. If I unmount the drive, all appears well, but
then removing the device results in corruption.

by default linux mounts the devices with the async option.
You can mount using the sync option, so you are sure that the I/O is

No. udev is basically for devices discovery and naming them in /dev.
Hehe; oh yeah, of course.
Before trying any sync mount option, try to manually sync disks with the
sync command to check if it fixes you issue.
Yeah, everything's fine

Didn't remember you already told it works with sync in your first mail,
sorry.

I've done it both from KDE and the command line, but I don't think that really
matters. It's the fact that large files appear to be copied instantly that is

You can try to edit the udev mount options:

/etc/udev.d/rules.d/99-mount-options.rules
Then you must reload udev rules:
# udevadm control --reload-rules
This seems like the right thing

Just FYI - Scripts updated to:
(1) provide a -f | --force option to the fduparch.sh (wrapper) script to
ignore the md5sum directory check and force a scan of all package and
duplicate directories. (by default if dir md5sums are unchanged, duplicate
scanning is skipped)

I know systemd and lightdm are not exactly kosher on ArchLinux, but any

With systemd running, it's responsible for setting the ACLs on the devices.
Try systemd-loginctl list-sessions and systemd-loginctl

Thanks for the hint.

Yes, it already is. https://bugs.kde.org/show_bug.cgi?id=273792
I find this really annoying. The solutions I've found is to use devmon

automounting system, and configured it to mount FAT32 with flush option.
