Can I over ride the disk check?

[Dave M G]

Ubuntu Users,

As everyone knows, every so often when you boot the computer, it forces 
a scan of the disk. I believe this is happening every 30 boots or so.

However, while I understand that this is a good thing and don't often 
have a problem, sometimes it happens at an inconvenient time. Like when 
I've turned my computer off and I have to rush out the house to a 
meeting, but then I remember I need to get a file off my computer, so I 
turn it on again... and it makes me wait. Quite a while with a 250GB HD.

[ctrl+C] doesn't seem to stop it, nor does the Escape key.

Is there a way I can stop it when I need the computer on in a hurry?
