    I have a "My Passport" from WD. It mounts as 2 partitions:
    /dev/sdb1 -> /media/sdb1
    /dev/sr1 -> /media/sr1

    gparted can deal with the sdb1 partition but fails on sr1. fdisk and sfdisk also fail on it, they all say it is read-only.
    Unmouting and remounting with
    mount -f /dev/sr1 /media/sr1
    Returns no error, and files can then apparently be copied to sr1 (still no error). But in fact nothing is written there.

    u3-tool also fails:

    u3-tool -p 0 /dev/sr1
    Error opening device: Read-only file system

    u3-tool -p 0 /dev/sdb1
    WARNING: Loading a new cd image causes the whole device to be whiped. This INCLUDES
    the data partition.
    I repeat: ANY EXCISTING DATA WILL BE LOST!

    Are you sure you want to continue?  y
    u3_partition() failed: Failed reading device property 0x03: Header of property 0x0003 could not be read.
    mary:/home/trouble# u3-tool -i /dev/sdf
    Error opening device: No such file or directory

    I know the partition is not physically read-only because WD offers upgrades for the junk which is on it.

    I would like to get rid of the sr1 partition and only keep the sdb1 partition. Any idea please?

    Same here.  Either the code needs to be updated or something in the kernel may have changed.

    # /usr/local/sbin/u3-tool -p 0 /dev/sr1
    Error opening device: Read-only file system

    Same result on Centos 5 and Fedora 14

    Also having trouble. It looks like the project has been abandoned and anyone who wants to alter U3 has to find an MS computer. The below is my most recent post over in the Ubuntu beginner forum:

    Re: Trying to locate U3 System device name
    Ubuntu 9.10

    Palimpsest Disk Utility shows /dev/sr1 mounted at /media/U3 System. That's a 101MB file, ISO 9660.

    but u3_tool -u /dev/sr1 and u3_tool -u /media/"U3 System" both return "unknown device name" when I plug that in. I've tried both with the fake CD unmounted and I've tried u3_tool -u /media/"U3 System" with the fake CD mounted.

    So, that's where I'm sitting now. It looks like I have the right path, but the U3 Tool returns an error saying I have the wrong path.
