Its nothing to do with stressing the disc. Without the DMA Manager, data is
transferred very slowly (~4MB/s) accross the system bus, instead of the
50MB/s+ which UDMA is capable off. However if you haven't had the hardware
mods done, such high speed bus activity causes stability problems.
While disabling the DMA Manager can be used as a temporary work around,
reducing the disc access speeds to similar to that of the Risc PC negates
one of the main advantages of the Iyonix, so getting it fixed is advised.
