Ok, that's interesting.

>[Yunfeng] Do you have any good way to get this kind of info?

Just comparing the source and destination file page by page (or byte
by byte) and working out the ranges of differences? 

(To make this even easier, start with a known, homogenous file (e.g. 
all 0xa5 or something) - on receipt check md5sum of each page, and 
note any differences in pages which fail the check). 

cheers,

S.
