When disconnected from that PC that detect it as "Write Protect On" and connect to another PC, it is immediately detected as "Write Protect Off". And in the past, the same disk can be mount on both PC as read-write. And seemingly it is repeatable and device specific - other thumbdrive all ok. With this, fdisk cannot write to the partition table, mount read-write cannot work etc. And specifically just on this PC. -- Regards, Peter Teoh -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
