    Server HDD Speed PRobs

    hi,
    i have a small problem with my new dedicated i have bought - it is all working fine and great except one small thing

    the hard drives are operating in PIO mode only and will not go into DMA mode - i get the following error when i do hdparm -d1 /dev/hda to enable dma

    hdparm -d1 /dev/hda

    /dev/hda:
    setting using_dma to 1 (on)
    HDIO_SET_DMA failed: Operation not permitted
    using_dma = 0 (off)

    this is absolutly crippling the server as you can probably gues as i am only getting about 3.9mb/s transfer from and to the disks, whereas my other server gets 28mb/s + to and from the disks

    any idea how to sort this ??

    thanks
