If you are referring to CheckDisk, just let it run through and it should stop running after that, until the system crashes or the power shuts off while in Windows.
If it keeps on appearing, test the Hard Disk for errors by using DFT.
DFT Download:

Download the ISO File and burn it to a CD-R Disc (There is also a Floppy Disk version if that's easier).
If you dont know how to burn an ISO file, read this guide:
http://www.petri.co.il/how_to_write_iso_files_to_cd.htm
Restart your laptop and boot from the DFT Disc.
Choose the "Advanced" Test and let it run (it may take an hour or so).
If you see a red message box, the HDD is faulty.
An error code 0x70 means there are bad sectors and the HDD needs replacing.
