        To find out what's using that filesystem,
use "lsof | protectedvolume", where
"protectedvolume" is the name that shows up on
the Desktop when it's mounted. You should see the
name of the process which is using the
filesystem. You could probably do the equivalent
with Open Files in Activity monitor.

I've had this problem and finally found that if any file in the
volume has been opened in Classic, it's necessary to stop or restart
Classic. Give it a try.

Did you try to relaunch the finder?

I have the same phenomenon when I am starting a slideshow of pictures
inside a disk image via the context menu (i.e., finder slideshow
function). The finder then often leaves some of the files open so
that the application finder still 'uses' these files.

Haven't found a way around other than relaunching the finder: ctrl-
alt-click the finder icon in the dock, and choose "relaunch" in the
menu. Caution: any unsaved window states etc. may be deleted by this
way.

HTH, Kei.

If you quit everything else and it doesn't help, try quitting Finder.
You can do this by pressing Option while bringing up the menu for the
Finder dock icon. A "Relaunch" command will appear in the menu.

If that fails, logging out/in should do the trick, saving you the
added overhead of a restart, at least.

You can find out exactly which file(s) are open by which processes
using the "lsof" command in Terminal:

   lsof /Volumes/<volume to eject>

If that doesn't reveal anything useful, invoke lsof with the "sudo"
command to see more processes:

   sudo lsof /Volumes/<volume to eject>

That should show you any processes that have files (or directories)
open within that volume.

Make that:

   lsof +D /Volumes/<volume to eject>

"+D" tells it to look for open files and directories within the given
directory.

 From reading the man page, +D actually checks every file and
directory on that tree, which can use a significant amount of resources.

I use:

lsof | grep <volume/file name>

which has always worked for me, and a listing just now includes both
REGular files and DIRectories.
