Do not play with idebus=XX setting, it's pointless. Instead run "hdparm
-i /dev/hdX" where X is the drive letter. It will print with which mode
and at which speed rate the drive actually works:
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
This example shows the drive is capable or PIO mode, DMA modes and UDMA
modes. And it shows that the current mode and speed is UDMA5.
