Ubuntu :: Disable Frequent Disk Checks In Lucid?

Since upgrading (fresh install) to Lucid, I've been having to go through disk checks about once or twice a week on boot. I'm not sure why Lucid thinks it needs to check my disk so often. I looked into it a bit, and found a command that was supposed to stop disk checks happening so often.

Code: sudo tune2fs -i 2w `mount | awk '$3 == "/" {print $1}'` is supposed to set it to 2 weeks. I used "/home" too as I have home on a separate partition and didn't want that to be checked too. All was fine until I booted up to find another disk check today. It can sometimes take over half an hour to finish and C to cancel doesn't always work either.

I always shutdown cleanly, unless Ubuntu completely locks up, which happens maybe once every six months (although it did happen yesterday, but I have rebooted it a few times since then with no checks happening until just now). Is there a way to just disable checks completely? I wouldn't mind running them manually every now and then, I just don't want to do it as often as Lucid does.
