fsck checks the filesystem not the hard drive. In case of a bad block or
any other hardware error, the result of using fsck is to have the kernel
fill the screen with error messages of the same type the guy already
have. I do not think there is a low level (ie hardware) test software
for Linux. I am not a disk expert but I guess such a utility would be
highly disk manufacturer dependant but may be some basic sanity checks
could be done by a relatively generic utility.
