My primary suspect is power supply problem but things like this are hard to prove. With the merged speed down fix, libata will do the right thing after a few errors, so ignoring the problem wouldn't be a too bad idea. If you're curious, you can try to connect drives to different SATA ports and power lanes and see whether errors follow the disk, port or power lane. -- 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
