    I just started to use xPC target. When I boot the target machine,
    there is a red error message "ERROR: No accessible disk found: file
    system disable."
    When I tried to connect from the host, There are red error messages
    "ERROR: -33:device driver resource error" and "ERROR: -4:drive not

    Found the answer.
    The target machine needs a FAT hard disk. I am using NTFS.

    Thanks for looking.

    Unfortunately, Microsoft hasn't made the structure of an NTFS file
    system public. We can't support NTFS partitions.

    Even Linux doesn't fully support NTFS, the driver isn't safe for
    writing to that file system.

    The next version of xPC Target will show one of the 'No accessible disk
    found' messages for each of the 5 partitions it tries to check for.
    Use the xpc explorer to see which partitions are actually found.

    The error message only effects the use of file system usage on the
    target machine. Other functionality isn't affected.

  4. Hi,
    I just found this forum while looking for a solution for the same problem.
    From what I read it seems that the problem should only influence file scopes functioning, but in my case the control works (from start until I stop the application the target controls the system) but as soon as I stop the model (via simulink or via xpcexplr or via matlab command window) i receive TCP/IP Connect error and no data appears either in workspace nor in scopes and so on on host computer.
    Do you have any suggestion?
