It would be pretty easy to screw things up if you pull out a device in
the middle of use.
When you insert a device like a USB stick Windows puts a little icon
next to the clock in the system tray that you're supposed to use to stop
the device before pulling it, effectively it unmounts and stops (or
atleast releases the device from) the driver so the device can be
'safely' removed.
This is useful, and something I think we need on the Linux desktop (stay
tuned).
I agree, that's one of the reasons I posted at all. Little things like
this can make a big difference, even though I've seen a lot of users not
notice the little icon and have to be told about it.
Maybe when the icon appears have a tool-tip that pops up and says
something like "your USB device is ready for user at /mnt/usb, click
here when you're done" or something like that to make it more noticable
that they shouldn't just yank it.
But I seem to be getting OT for this list...
I also believe Windows mounts any removable device
synchronously so that if you do pull it out prematurely the damage done
is limited.
Eww, I hope not, that would be excruciatingly slow. It might adjust the
buffer writeback to be really short (even nearly immediate) but
synchronous I/O is a different story, and much slower.

Perhaps synchronous was the wrong term =) But it does atleast seem to do
less buffering for removable devices or I could just be fooled by
something else slowing it down.
