"Cannot mount volume" error message when connect usb stick to ubuntu 8.04

When I insert a usb stick into my laptop running ubuntu 8.0.4 I get the error message:
"Cannot mount volume.
Invalid mount option when attempting to mount the volume"

The same usb stick works find when I connect it to another windows box. I ran a chkdsk /f on it and got no error messages.

It's also not a hardware issue with the laptop since the same usb ports work fine when I boot it until windows (dual boot machine).

The file system on the usb stick is FAT.
Is the USB stick formatted with NTFS as file system?

The NTFS support in linux isn't great and i suggest you backup your data and reformat it to FAT32 if you want good portability between linux and windows

You didn't properly remove the USB stick at some point.  Please re-insert it into a windows system and do a chkdisk on the stick.  It will work properly when you re-insert it into a Linux system.
It might be the the mount point on your ubuntu system is missing. i.e. you have automount running and when the usb stick is being inserted it tries to mount it on /dev/media/usb /media/external, but this mount point does not exist.
Check /var/log/messages to see where it was trying to mount it.
