Half of the time I'm dead serious.
The other half not so much.
If you have already gotten 29 logs (which it sounds like you have) you have to go to Data Hive and when you meet up with the random ODST, you'll notice that instead of him being killed by the flying bugs when you drop down that one time he'll actually come down with you (because you found the logs). Then, he will follow you a bit and then say "Hold on I have to go somewhere, don't follow me," but secretly follow him to an icy room with the last log. You have to kill him to get it. I'm assuming that you are doing everything right, just make sure that you FOLLOW him at the end, otherwise you won't get it.
