There are combinations of IDE + disk that slowly corrupt filesystems with DMA on, if the default setting is DMA off _don't touch it_. Not all bad combinations are catched by the code in the kernel (intel + some Western Digital disk is what drove me up the wall until I disabled DMA).
What machine is this, what disk?
