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.

You can mount using the sync option, so you are sure that the I/O is
made synchronously.
Just remember: In case of media with limited number of write cycles

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

How do you umount the USB device?
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
frustrating.

You can try to edit the udev mount options:
# echo 'ACTION==add, ENV{mount_options}=sync'
/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

There can't be any corruption after a successful unmount.
1. Run sudo umount /path/to/mounted/dir; echo returncode=$?
2. If you see 'returncode=0' on the last line, continue with 3.
3. Remove your USB drive.
4. Attach your USB drive.

I find this really annoying. The solutions I've found is to use devmon
(https://aur.archlinux.org/packages.php?ID=45842) instead of KDE's
automounting system, and configured it to mount FAT32 with flush option.
