Safely disconnecting Garmin GPs from computer

The reason why it is necessary to "Safely Remove" certain USB devices is because of cached writes. In order to improve performance, the Windows OS will delay writing data to a disk drive because it is a fairly slow operation. When you click on the "Safely Remove" icon, you are telling Windows to write any cached data to the disk. You won't get the safely removed message until the data is safely written.

Since the GPS isn't a disk drive, writes aren't cached so there's no reason to "Safely Remove" it.

You can turn off cached writes for a drive so that you never need to worry about safely removing it. You'll give up a little performance though. Enable/disable Disk write caching
