ok, in answer to my own question, i did some research on filesystem
checking, and discovered 'tune2fs' is the programme i need to set the
fs to be checked at regular intervals

this is the command i came up with, i.e. to check the internal flash
every 10 mounts

tune2fs -c 10 /dev/mtdblock6

i chose mtdblock6, as it's the filesystem listed in fstab, which is mounted to /

when i run this, it gives me an error:
tune2fs: Bad magic number in super-block while trying to open /dev/mtdblock6

which i don't entirely understand. any suggestions what's going on here?

cheers
