Description: ATA Disk Transfer Mode.
other(1) The agent cannot determine the transfer mode on this ATA disk.
pioMode0(2) The ATA disk is using PIO mode 0.
pioMode1(3) The ATA disk is using PIO mode 1.
pioMode2(4) The ATA disk is using PIO mode 2.
pioMode3(5) The ATA disk is using PIO mode 3.
pioMode4(6) The ATA disk is using PIO mode 4.
dmaMode0(7) The ATA disk is using DMA mode 0.
dmaMode1(8) The ATA disk is using DMA mode 1.
dmaMode2(9) The ATA disk is using DMA mode 2.
ultraDmaMode0(10) The ATA disk is using Ultra DMA mode 0.
ultraDmaMode1(11) The ATA disk is using Ultra DMA mode 1.
ultraDmaMode2(12) The ATA disk is using Ultra DMA mode 2.
ultraDmaMode3(13) The ATA disk is using Ultra DMA mode 3.
ultraDmaMode4(14) The ATA disk is using Ultra DMA mode 4.
ultraDmaMode5(15) The ATA disk is using Ultra DMA mode 5.
What is cpqIdeAtaDiskTransferMode?
This enumerated value reports which ATA transfer mode (PIO mode 0-4 or a DMA mode) the disk is currently using to communicate with the controller. An admin checks this when diagnosing unexpectedly slow disk I/O, since a drive stuck in a slow PIO mode instead of DMA indicates a negotiation or cabling problem. For example, seeing pioMode0(2) on a modern drive that should be using a DMA mode would point the admin toward a cable or BIOS configuration issue.
