solving android partition problem

The Android operating system
partitions the internal storage
of your device into different
sections, including sections for
user data and cached data for
frequently-accessed apps. You
can clear the data and cache
for individual apps on your
device, or boot the device into a
special recovery partition. From
the recovery console, you can
wipe all cached data from the
device, as well as clear all data.
App Data
Step 1
Press the “Menu” button and
tap “Settings.” Touch
“Applications.”
Step 2
Tap “Manage Applications,”
select the “All” tab and touch an
application name.
Step 3
Touch the “Clear Data” button
to wipe the app’s saved data. Tap “Clear Cache” to
remove any cached data for the app.
Phone Data

the Motorola icon appears. Press the "Volume-up"
