You can run fsck with the "-n" option (assumes a "no" response to all
prompts) on a mounted file system, but some inconsistencies are
to be expected in the on-disk metadata for an active file system, so
the result is likely to be more confusing than useful unless you
really know what you are doing (and thus probably wouldn't have asked
this question).
If you just want to check for physical drive problems, running
dd if=/dev/hda of=/dev/null bs=32k
will attempt to read the entire device and abort if it encounters
and unreadable sectors. Replace "hda" with the appropriate device
or partition, of course.
