hi Leo

Can you please explain on how you calculated the flash of 3850 48p as 2GB. I can see that 

3850#sh file systems 
File Systems:
    Size(b)     Free(b)      Type  Flags  Prefixes
     248354816     244812800      disk     rw   crashinfo:
*   1621966848    1269755904      disk     rw   flash:  

So, 1621966848 = 1.6GB right ?

It would be really helpfull if you help me on how you calculated that.
