Chapter 1 Managing Removable Media (Overview)
This chapter provides general guidelines for managing removable media in the
Solaris environment.
This is a list of the overview information in this chapter.
Where to Find Managing Removable Media Tasks
Use these references to find step-by-step instructions for managing removable
media.
For information on using removable media with File Manager in the Common Desktop
Environment, see Solaris Common Desktop Environment: User’s Guide.
Removable Media Features and Benefits
The Solaris environment gives users and software developers
a standard interface for dealing with removable media. Referred to as volume management,
this interface provides three major benefits:
-
By automatically mounting removable media, it simplifies their use.
(For a comparison between manual and automatic mounting, see the following section.)
-
It enables you to access removable media without having to become
superuser.
-
It allows you to give other systems on the network automatic access
to any removable media on your local system. For more information, see Chapter 2, Accessing Removable Media (Tasks).
Comparison of Automatic and Manual Mounting
The following table compares the steps involved in manual mounting (without
volume management) and automatic mounting (with volume management) of removable media.

What You Can Do With Volume Management
Essentially, volume management enables you to access removable
media just as manual mounting does, but more easily and without the need for superuser
access. To make removable media easier to work with, you can mount removable media
in easy-to-remember locations.
