Mac OS X: Do Not Use the Solidus ( / ) or "Slash" in a Volume Name

A solidus ( / ), or "slash," in a volume name may cause a "nonexistent path" alert message when attempting to save a file on that volume.
Symptom

When attempting to save a file, an alert box with this message appears:

Products Affected

Solution

Remove the solidus from the volume name.

The alert occurs because Mac OS X uses the solidus to define a path to a location in the file system. The solidus in the volume name is interpreted as an attempt to specify an additional part of the path. For example: If the name of your Mac OS X startup disk was "OSX/10.1", it would be interpreted as an attempt to specify a folder named "10.1" inside the disk "OSX".

Note: This document does not apply to disks using the UFS file format.
