error about /dev/hda2

after i copy some picture to my /dev/hda2 in windows(use ex2explorer),then, when i turn on linux, it said the block of /dev/hda2 is not ?good?

then i use e2fsck, but it still keep saying bad block, what can i do?
i am using ext3!      
with ex2explorer under windows you can write your linux partions???
I can't do it! why?!      
劝你不要把write support打开,
我打开后,在加了几张图片就不能用LINUX分区了!!!!!
