The previous poster specifically mentioned VFAT, which afaik is not in any way journalled. OS write caches and journalling are two separate things. Whenever you use a removable device, you should always take care to correctly unmount it before you remove the device. dragging the files and then ripping the device out as soon as nautilus's progress bar finishes is pretty much guaranteed not to have written your data to the device, or worse, may have written part of it, or even worse, partly updated the fs metadata (a very very bad time to remove the device as you can easily hose the whole fs). When you right click on a removable device in Dapper and tell it to unmount/eject, you get another progress window that shows the actual writing (and if you have a removable device with an LED on it that shows accesses, you'll notice that this is when it does most of its blinking). If you're super paranoid, some judicious calls to "sync" will ensure that outstanding write caches are flushed to disk before you remove the device, but this is basically what the dapper unmount progress window is doing, afaics.
