your file is damaged and cannot be repaired

  1. Default your file is damaged and cannot be repaired

    We are using Illustrator as part of our CS2 licence in a school. The
    workstations run XP Pro SP2 and are equipped with 1 GB RAM and Intel
    Celeron CPU 2.66GHz motherboard with Intel 915GAG chipset.

    At this end of the year, students start producing some pretty sizeable
    files (> 10 MB) and have been exceeding their network storage quota.
    To get around this they have been been saving their work to USB thumb-
    drives and external USB (eg Maxtor OneTouch 250 GB drives). Students
    (and teachers) are hopeless at managing their files, therefore quotas
    are necessary.

    All of the affected drawings are in Adobe Illustrator CS2 format and,
    as far as I can tell, include objects "placed" from Photoshop CS2
    images.

    When they go to open a previously-saved drawing they get the message
    "your file is damaged and cannot be repaired" although the thumbnail
    shows a miniature of the drawing correctly.

    OK what might the causes be?

    .. USB caches output and student removing drive before writing has
    finished: This was my first explanation but the Graphics teacher
    assured me that students *always* wait until the light has stopped
    flickering before removing the USB drive. I also put a utility on the
    student menus to "eject USB" (RemoveDrive by Uwe Sieber - www.uwe-sieber.de
    - a good utility that can be looped until it can detect that all files
    are closed on the USB). I can't guarantee that all students who *say*
    that they have safely removed the USB are telling the truth but we've
    had so many file corruptions that I doubt that they are all stretching
    the truth.

    .. Illustrator unable to cope with large (> 10 MB) files being written
    directly to media such as external USB thumb drives

    .. Windows Update: Everyone is hazy as to when this started occurring
    but the best indication that I can get is "in the past month". So
    could it be caused by a Windows Update that's gone awry? We are
    running WSUS from our Network so updates are sent out to workstations
    as they are approved. The updates that went out in the "past month"
    are K936021, K938829, K838828, K921503 and K936782. Anyone aware of
    these updates causing problems?

    .. The technique: As I reported it seems that all affected files were
    created by "placing" files that were created in Photoshop CS2. Are
    they any "known issues"?

    .. CS2 bug-fixes and updates. The Adobe updates are not downloaded
    during the year but is it possible that an Adobe update *might* have a
    fix for a known Illustrator bug?

    The students are in their final few weeks before assessment and I am
    trying to make sure that things work right.

    I'm stumped as to the cause. Perhaps someone out there has seen this
    happen before. For my own part I will be raising quotas for students
    who are doing Graphics subjects in case the USB is the issue. Any
    other ideas/suggestions?

    Thanks

    I think you are on the right track with the USB issue. I used to have
    some similar issues when saving to a thumb drive. I did notice they
    were fewer when i saved to the local HDD then dumped my files on the
    USB stick. As far as the "placing ps files from cs2", never had any
    issues there. good luck..
