I've got a brand new .5U P4 system running several (I think) Seagate 80gig SATA drives. I tried to copy data from the first drive (sda) to the second drive (sdc) and was only getting about 1.7megs/sec. So I figured DMA was off. And this is what happened when I typed "hdparm -d1 /dev/hdc": /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) Any suggestions? I've never had this type of problem before. Thanks,

It was overcome by plugging in a SATA pci card :-) -- Sudev Barar Learning Linux
