This is vital, you court a real disaster if you attempt to fsck it 
mounted.
Doing that will really ( euphemistically ) fsck it.
 

There is a -check option which allegedly runs on readonly mounted 
partitions.

Also note that because your device is not mounted you file check a 
filesystem
by using the device name - NOT the mount point i.e.:-

fsck.reiserfs  /dev/hda6
_NOT_
fsck.reiserfs  /mnt/hda6
 

well, sort of. Selecting the device file makes no difference to 
whether it is mounted or not. There are also some specific tools in 
addition to fsck, like a debugger which can help pinpoint problems 
with this system. Same goes for XFS formatted systems, though I'm 
heartily sick of them screwing up on me ):

Anyone tried reiser4 yet?

Sorry to reply out of sync, but I've just done something rather strange 
with Chris's response to this one! Not long changed to Mozilla, that's 
my excuse!

I have one system that decides, every now and then, to replace a handful 
of files with ones that are exactly the same size, but full of nulls. 
It's only 20 or so files, and they seem to be the last accessed, but I 
can't be certain. I've also had a half dozen or so that I had to junk 
the journals after power failures, just to get them up and running 
again. For some reason, most of these seem to be SCSI disks. My current 
pet theory is that it's a problem with managing the on-board buffer 
cache, as they are often 4 or 8 MB these days.

That, and the limitations of where you can stick lilo ( I still find 
grub too cumbersome to use effectively... like manually trying to boot 
into single user mode if there isn't an entry available! ) puts it at 
the bottom of my list of favourite file systems. I tend just to use ext3 
these days.

Cheers,
Steve
