Cannot unmount USB flash drive

[thornspear]

I've recently purchased a 4gb "ultra speed" flash drive. It reads and writes just fine on both my laptop and desktop. Both of which are running Ubuntu 9.04.

However, when I go to unmount the drive from my desktop system, the drive icon on the desktop disappears, but it remains in the "media - File Browser".

There is one change in the file browser though. When I unmount the drive, the "eject" symbol disappears from next to the drive in the "media - File Browser" but the drive icon itself remains.

The light never extinguishes on the USB drive, and when I click on the icon that remains in the File Browser, the USB drive mounts itself again and reappears on my desktop and the eject symbol reappears in the File Browser.

This drive unmounts just fine from my laptop.

Here's some code that may or may not be useful... let me know if anyone can help and if you need more info.

Thanks

I think this is a normal behavior. In my case, when I unmount, or safely remove the USB stick, its icon still remains until I plug it out completely. Is this happening on your PC too? In that case everything is O.K. there are no errors at all.
