Hmm... have you checked to make sure you have the appropriate chipset-specific IDE DMA support enabled? This can make a difference. I generally set CONFIG_IDEDMA_PCI_AUTO to make sure that the DMA settings are automatically set to the correct values. (I'm not an expert on hdparm to set DMA/Ultra-DMA settings, but I'm not convinced -d1 is sufficiently to completely set up the DMA settings correctly.) So I prefer to let the kernel set everythign up for my correctly. - Ted _______________________________________________ Ext3-users@redhat.com https://www.redhat.com/mailman/listinfo/ext3-users
