Ouch. Sounds bad. In general, you should _not_ use hdparm, for the simple reason that if you build a custom kernel with all the necessary options, it will default to optimum performance anyway (you can set "Use DMA by default" under the block device options). I'm running a 2.4.5 XFS patched custom kernel that I built, and DMA/32 bit disc access etc. is fully operational by default since I selected the appropriate kernel options. With modern kernels, hdparm is totally unnecessary and potentially dangerous (except for performing performance tests on your drive of course!). What chipset does your mainboard use? John.
