Here it is:

I have put 'hdparm -w /dev/cdrom' into resume part of one of s2ram hooks. Now, 
I have asked few people about 'w' option. Option have 'dangerous' tag, but 
none of people have provided good reason why not to 
use 'hdparm -w /dev/cdrom' in terms of system stability, kernel health and 
hardware health. I used s2ram few times this morning and it works without 
problem.
