When a 3TB SATA drive is connected through a JMicron JMS539 (USB3.0 to SATA Bridge, 152d:0539), Windows sees 3TB and Linux sees 3TB. When the same drive is connected through a JMicron 20337 (152d:2338), Windows sees 3TB but Linux sees 800GB. (Fortunately Linux avoids mounting the truncated partitions.) -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
