Thanks very much, Robert, it was the udma option : but this is quite inefficient if I can't use UDMA with FreeBSD ?

FreeBSD will drop down to PIO mode, probably mode 4.

According to Scott Mueller's book, PIO mode 4 offers up to 16.67 MB/sec, whereas UDMA can offer up to 100 or 133 MB/sec. So, yes, less efficient (but also a bit quieter in my experience).

And the cpu load should increase, no ?

Have you been able to switch the data cable for a know good cable? That solved the problem for me.

I've tried a brand new one, but no difference...

Best regards,
