dual boot question about mouse and check disk

[integrity]

I have dual boot system xp and kubuntu everything has been ok exept now I am in winxp and my synaptics touchpad motion of the mouse is slowed down.I really have to drag my cursor around.

Also when I restart and select win xp from menu i automatically get the blue screen asking me to check the disk then it has the counter but i can hit any key to bypass. Is this normal?
