read/write less than sector size

if i open /dev/ad1s1 for example, i try to read() or write() not in multiples of 512, it will return an error. how would i do this? currently, if i need to read 100 bytes, i read in the full sector, then memcpy the bytes i need. is there a better way? -- thx, Nehal
