The smartctl man page is a little vague, but it looks like it does no 
writing.


Paraphrasing somewhat:

short selftest - The  "Self"  tests check  the  electrical and 
mechanical performance as well as the read performance of the disk.

long selftest - This is a  longer  and  more  thorough version  of the 
Short Self Test described above.
