You mean raw read ???...from kernel ?? I am not sure if this is correct ,but you can do something like this if you have the filesystem over it. sb=<superblock of filesystem> struct buffer_head *bh = sb_bread(sb,blocknumber) blocknumber would depend on which sector do you want to read and what is the blocksize of the filesystem.......so rougly blockno = (sector/(sb->s_blocksize/512)); The contents of your sector would be in bh->b_data .
