you have to unmount partition and run it like this:
PHP Code:
e2fsck /dev/discs/disc0/part1 
However the first can be tricky. I suggest the following procedure:
switch off router
disconnect usb device to be checked
switch on router
30 sec later connect usb device
then do
PHP Code:
umount /opt 
do similar operation for all mount points on this device which you can see by
PHP Code:
mount 
after that run e2fsck
