there should be no problems with running this on a software raid
system. That is, if your sure it works, I don't use hdparm but it
looks like you may be trying to enable DMA, be sure your chipset
works well with linux in DMA mode before attempting this. Some systems
have serious problems with DMA turned on, most do not though.
