Normally the kernel automatically sets the proper transfer rate and mode
automagically. There are just few cases where it makes sense to override
I does not only matter for which transaction mode your hard drive is
capable but also which modes the IDE bus controller chip supports. Given
that your motherboard/IDE controller supports UDMA5 too like your hard
drive, then you can change the mode with:0)100MB/sec
hdparm -X69 /dev/hdX
But if your motherboard only supports ATA33 (UDMA2) or you have just a
40pin IDE ribbon cable the change will not happen or change anything.
