here is a digged post about changing the harddisk transfer mode
66 lines of 80 chars each line, 12 steps procedure if you want first to see what is you current transfer mode and if you do no mistakes by clicking wrong buttons.
at the end you get the thing done.
Here is an example how I do the same procedure on a Linux machine:
#hdparm -i /dev/hda|grep modes
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
you see the red asterisk? thats my setting,cool, let’s imagine I have the same problem as the poor guy in the article has:
#hdparm -i /dev/hda|grep modes
PIO modes: pio0 pio1 pio2 *pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5
now it’s on the pio3, let’s change it:
#hdparm -X udma5
that’s all
So, speaking honestly, which system is easier to use?
