Mounting and unmounting flash drives - RHEL4
My problem involves trying to understand exactly what happens when you mount a usb flash drive. In RHEL4 I can mount the flash drive, and unmount it successfully, but the directory structure from the drive still seems to be available under /media/disk. Drive has been unmounted and removed.
If that is not so clear, can anyone point me to a good tutorial on mounting and using external drives?
