(I didn't run hdparm on my machine, because I'm waiting for a flasher that doesn't require XP. I just copied the output from: http://www.ocztechnologyforum.com/forum/showpost.php?p=371277&postcount=28 ) -- Markus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
