Hi, this afternoon I realized I have the same problem. I never noticed before because i often work with FAT32 or EXT filesystems, that aren't affected from this problem

The drive still kept writing for a long time. Mount shows the drive still mounted for the period while the flash drive keeps blinking though "df" does not show the drive anymore. Removing the drive at this point results in partial file write and NTFS filesystem damage (fixable with ntfsfix but dangerous). Steps to reproduce: 1) Insert a flash drive (tried with NTFS mounted drive though I believe FAT will show similar behaviour though latter uses "flush" mount option so may not be that prominent) 2) Try copying a large file. For testing use a size that will also mostly fit into filesystem cache so that real wait for writing is during unmount: dd if=/dev/zero of=/media/<user>/<drive>/test.out bs=1M count=1000 <user> is the user name and <drive> the name where drive was mounted by nautilus as per the label. 3) "Eject" the drive from nautilus context menu after dd command above returns. 4) Eject returns shortly. However drive is still writing as seen by the blinking, or disk throughput in gkrellm, iostat. Also note that "mount" still shows the drive as mounted though "df" and other tools don't. I have confirmed the same issue exists on all similar file managers namely nemo and caja. Haven't filed bugs against those yet. For comparison, the gnome-disks system utility correctly unmounts, ejects and stops the drive (last one even powers down the drive so the LED on drive is switched off which one would expect nautilus "Eject" to also do) so it doesn't seem to be a bug in udisks2.
