I have just installed Fedora 14 on my brand new Force 120 and the disk utility (2.30.1) reports that SMART indicates 832 bad sectors (5 - Reallocated Sectors). Is there a way to confirm the health of my disk on Linux? I am willing to install any (free) distro if necessary. I am already having some crashes with firefox and I really need to know if this is because of the disk or something else (cant imagine what though). If there is no way of confirming this then I will have to return the disk as faulty.
