hard drive integrity checker?

[dsawan 613]

Hi, guys. Does anyone know of a hard drive disk integrity checker where you can burn to a cd and put into the pc to check it. I think my hard drive is going and I muse to habve a program that was on fl;oppy disk and you put into the floppy drive and it tells you if the drive needs repacing. cant remeber the program. Is there one you can put to a cd? My pc is hanging at the HP invent screen and keyboard is unresponsive. This is constant and started suddenly. thx.
