help with hdparm
...O_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 15733/16/63, sectors = 15858864, start = 0 when I do "hdparm -d1 /dev/dhc" I get /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) I get operation not permitted. How do I enable DMA mode for this device? Jerry

hdparm strangeness
...al (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,
