Mac Host + Linux Guest + SharedFolder issue

[miragetetra]

For some reason while trying to mount folders between a Mac OS 10.6.3 host and an Unbuntu 10.04 LTS guest I keep getting the following message:

"/sbin/mount.vboxsf: mounting failed with the error: No such device"

The command I'm using to mount (on the guest) is

"sudo mount -t vboxsf notes ~/desktop/notes"

The only thing I can find concerning this error message is:
"Q: I get a protocol error when mounting.
Q: I get the error /sbin/mount.vboxsf: mounting failed with the error: No such device.
A: You mount the SF on a mount point with the same name as the share itself, change the name or mount point.
A: You're sharing a personal folder like your Home Folder (Linux), or My Documents (Windows) on the Host. Define a new share, like a sub folder."

That said, I have the lastest "Guest Additions" installed as well as the latest version of VB . The sharedfolder in question sits on my desktop on the Mac host and the mount_point sits on the Desktop of the Ubuntu guest. My sharedfolder options are set up correctly and the path of the sharefolder is pointing to where it should be. I've tried moving the sharedfolder on my mac to my Public folder (with filesharing active) as well as moving the contents of the folder to another folder, nothings worked so far. I'm at a lost as to what I should do next to get this working so any help would be very much appreciated

Try changing the mount point to something more generic like /mnt/<share name> and see if it works.
I had a problem with trying to mount the share to the desktop once, maybe that is your problem. Also if you are going to mount to your home folder use the complete path and not the ~
/home/<user name>/desktop/notes
You did create this folder called notes on the desktop, right?
