Formatting Media

 

 

 

 

TIP

 

To format media used by other applications, use the Force Operation

 

 

option. Data Protector protected media cannot be re-formatted using this

 

 

option. You have to first remove the protection. See “Recycling Media” on

 

 

page 123 for more information.

Once you have formatted your media, you may use these media for
