Built-in storage not detected well I just bought a lenovo s920, at the first time I'm doing a system update and it works fine, then I'm doing another system update S920_ROW_S114_130626_TO_S920_ROW_S117_130815 (79.83MB), I dont know if it's failed or what, after that my built-in storage not detected. I keep getting notification "Damaged Built-in storage" that asking me to format and even I'm doing it, it cant be format.

My Storage setting become like this:

INTERNAL STORAGE
Total Space: 3.62GB
Available: 379MB

BUILT-IN STORAGE (no information)


then when I check spaces with app Freespace:

Cache /cache:         Total space-&gt;   123.08MB
Internal /data:       total space-&gt; 1,008.29MB
Preload /preload:     total space-&gt;   197.01MB
Protect_s /protect_s: total space-&gt;     8.89MB
System /system:       total space-&gt;   788.39MB
                                    2,125.66MB


so there's missing around 1,400MB.
I guess this is built-in storage, how can I recover it? and create it again as built-in storage.
HMM the only thing I can think of would be to get clockwork or something similar and format the space and reflash the rom.
