Well, yeah, but given the concept of how UNIX mounts volumes, it would make sense to check in /Volumes first.
I dunno if you know this, testuser, but I might as well post it so that everyone knows the concept. UNIX basically assigns a folder to an external hard drive and "posts" all of the contents in there, and then the Finder presents it on the desktop as a volume. So you're actually accessing a folder inside /Volumes when you open a volume.
To put it more simply: whenever you connect an external storage device, be it FireWire or a CD you put in your internal hard drive, UNIX creates a folder inside the /Volumes folder, and links that folder to the external storage device you just inserted. Then you can do the changes you want or read what you want off of that, and then when you eject the device visually, UNIX deletes that link, so it's not there anymore.
So the reason that I thought to look in the /Volumes folder even while the mp3s were taking up space on the hard drive was this -- when renaming the external hard drive, LimeWire was trying to access that drive, which for some reason it actually interpreted it as the folder, and so it just created a new folder inside the /Volumes directory and dumped all of the contents into there -- now it really isn't a link to an external storage device because of this fluke; it's just an ordinary folder, and UNIX won't delete it because it was never linked to a storage device originally. So it is actually residing on the internal hard drive, because the folder is actually there in the /Volumes directory, which is on the internal drive.
Catch my drift?
OK, by the way, I forgot to add something that would probably allow you to access the files via the Finder. You know the third-party preference pane called TinkerTool? If you don't, you should.
You can download it from
www.versiontracker.com -- just drop it in your "PreferencePanes" folder inside your "Library" folder that's in your home folder; if that folder doesn't exist, then create it.
Now go to System Preferences, click on "TinkerTool" at the bottom in the "Other" category, and then in the "Desktop" tab (which should be the one that's shown when you click on TinkerTool for the first time), check the "Show hidden and system files" checkbox. Ignore the little notification that you need to logout and login for changes to take effect.
Now press Cmd-Opt-Esc, and select the Finder, and press Relaunch. Now the Finder should be showing all invisible folders, one of which is the /Volumes folder. You should now be able to navigate manually to the ghost mount point to copy all of the files. I'm not sure if you'll be able to delete directly via this method, but it's worth a shot -- the Terminal should always work.
To put the Finder back to normal, just go back to TinkerTool, uncheck the checkbox, and relaunch the Finder again.
Hope this helps.
