sectors. But I am a perfect newbie on that,so please give me some
suggestions for implement it. And any reply is appreciated :p

What does your boss think he will achieve by writing to these? There is a
high probability of making the data on the disk unusable. Tell us what the
goal is here and then a safe solution may suggest itself.

Anyone ever try to read say a compact flash this way? The calls always
succeed and you never know when the end of the media is reached or am I
missing something. The data does appear to be read but when the end of the
media is reached junk instead of an error, 0 bytes read etc. seems to be
returned.
