I have a huge external usb drive set to be auto-mounted during backup processes and did not want to run fsck on every mount. With the below setting it would completely turn off the auto fsck check.

tune2fs -c 0 -i 0 </dev/partition>

However, I would highly suggest atleast doing a regular 6 months check if not doing manual fscks.

tune2fs -c 0 -i 6m </dev/partition>
