    I would first question why you have 2 drives with the same OS installed. I can only assume that because both drives have the same layout that the system becomes confused as to which drive it should be writing to thus it marks them as RO to avoid problems.

    Is one drive to be a copy of the other? If so then you should look into RAID1 setup.

    Hi,Lazydog,
    Thank you very much.The first drive's os was updated by me,and now the root fs has some problems.So I need a copy os,If I can't setup the copy os on the same drive. So I install the second drive on the board.
    and I want to copy some important root directory files from the first drive to the second drive ,Then I can do some experiments. If I faild ,The first os still there.

    I would make life simple and boot from a rescue cd then mount both disk and copy what I need from one disk to the other.
