After I transfer data back and forth from my phone to my Fedora 8 desktop, I right click over the "Memory Card" icon on the desktop and choose Unmount, and I wait while it says "please wait writing data..." and when that's done, I unplug the USB cable.
The phone always complains that the cable was disconnected while data was being written, blah blah. No apparent data loss took place. Is the phone designed to expect some windowish signal when it's unmounted, I wonder?
