I'm going to have to time how long it takes for a remount to take place. There may be different defaults on Slack then there is on Fedora.

Edit: Interesting, I think that in Fedora KDE the problem is fixed. It's not remounting itself. I bet anything that is was the Gnome 2 DE in Fedora 14 that was causing the problem (Or maybe it was just Fedora 14). So, since I started running Fedora 15, I've been rushing to remove the usb stick before it remounted, and, I didn't have to. I'm glad I found this out.

Yes, I'm seeing this as a problem. After transferring files via flash stick from a F14 Gnome HD to a F15 KDE HD I was met with the 5-10 second remount on the F14 Gnome side. On F14 Gnome I had to use the "eject" choice in the menu to get an unmount. Hitting "Safely Remove" and (after the remount) "eject" would give me enough time to remove the stick. Guess it depends on what distro and what DE your using. BTW - If that led light is not flashing and is solid, It's not showing data transfer, it's just showing active connection.
