Storage Manager
The Storage Properties applet uses the Storage Manager tab to set up
and view storage devices on your Allegro. This applet allows you to
scan and defrag partitions on your Allegro, and format PC Cards and
gives you the option to format your C_Drive. This applet is an
advanced function and should be used with extreme care and
caution, because of this when you open this applet, you will get the
following warning:
To format a PC card, complete the following steps:
1. Insert the PC card into the PC card slot in your Allegro and turn on
your Allegro.
2. Tap on Start| Settings| Control Panel and double-tap on the Storage
Manager icon.
