Unmount the disk in the Finder by selecting it and choose File > Eject “Volume Name”, press Command-E, viewing the drive in a Finder window and clicking on the Eject button, or right-clicking the volume and selecting Eject “Volume Name”.

Interarchy populates the folder with files and subdirectories and shows its progress. To unmount a disk, you must use the Net Disk view in Interarchy. Select the volume and click unmount. If you have Interarchy’s menu icon enabled (Interarchy -> Preferences, General pane), you can select a defined Net Disk from the menu’s Net Disk item to mount it.

Both Transmit and Interarchy are worthwhile options to provide access to remote file servers without the fuss of working through a program’s interface.
