Sorry, Justin, if I wasn't clear. I was asking the N00bee question about _my_own_ machine. The output of lspci (on my machine) seems to indicate I have a "real" STAT controller on the Motherboard, but the contents of "dmesg", with the references to ATA-7 and UDMA/133, made me wonder if I had just an ATA-SATA converter. Hence my question: how does one tell definitively if one has a real SATA controller on the Mother Board? - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
