Default [Q] Question for those with ULF kernel

At the lag fix recovery screen, there is an option for disabling lag fix... I was wanting to know if that will disable any of the lag fixes that you selected, I selected the last overkill option, just because I read in a post that it would repartition your internal SD card. I was one of the unlucky ones whos got wiped. It did repartition it. So am I ok to undo the lag fix? Will it un-repartition my card if I do? Im pretty sure I made that word up.
