Comment 21 for bug 211760

One point to note is that when a person decided to unplug the USB device like thumb drive or MP3 Player, it will show

Unable to Unmount Volume
Volume 'My Disk' (Which is the name I gave to my thumb drive, this varies from each USB devices) possibly mounted through command-line manually.
Detailed Message:
Device to unmount is not in /media/.hal-mtab so it is not mounted by HAL.

Notice somewhere near the recycle bin icon, on the bottom right of the image, there is some message. It is as follows:

Writing Data to Device
Before deleting the device 'San Disk Cruzier Micro' (Which is my thumb drive's brand), there are data to be written on. Please do not unplug the device or disconnecting it.

PS: This message is not shown during my attempt to remove my MP3 Player. I did not copy, edit. move any files. Not even view. Also, my creative MP3 Player (Zen Stone) is not correctly shown the number of items and filename (All my music were Chinese were affected, either not shown or full of ??.mp3 (.wma, as my file are some MP3, others wma) , ????.mp3 (.wma) etc the default music by this player are named in English, which are not affected.)
