Data transfer from the host to the drive fails and SError indicates Handshake Error, Non-recovered transient data integrity error and often Recovered Data integrity error. For some reason, your drive doesn't like what it's hearing from the controller and replies with R_ERR.

It gets reported as host bus error but I think it's basically the same problem. I don't think this is driver issue. I have the same controller and I've never seen similar thing happening and I have plenty of drives and test them often. Error reports also point to transmission problems. Your drive just doesn't like what it's hearing. Does 'smartctl -a /dev/sda' tell anything special? -- tejun - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
