If I get the "please try later" message, it usually means that something is accessing the device. In my case, this is typically either virus scanner or backup software or windows indexing service (which seems to have an ability to restart itself no matter how enthusiastically I tell it the service should not be started...
). Typically these are background things that I have no real idea if they are running until I get these sorts of messages.
Now most of those only read data, so generally unplugging at that point doesn't cause a problem, but at least some filesystems (NTFS is an example; I'm not sure about FAT) do keep markers that say a filesystem is "in use" which can confuse things. Also, without knowning how the device behaves, it is possible that it gets confused if it is trying to respond to a read request to a host computer from which it has been disconnected. This is typically why remove processes say "Please wait" at this point (it can also cause nasty problems for the process reading the data, if it is not well written...).
I have used the shutdown/restart to release the device in which case I pull the USB cable out once the host computer has shutdown.
