Here’s the answer to the Cannot create projects or scenes – The disk is write-protected case I mentioned in my last week on the frontline post.
If you get this “the disk is write protected” error when you try to save a scene, it’s probably because you are trying to save your scene in the XSI_SAMPLES project. The XSI_SAMPLES folder is in the Softimage installation folder (in C:\Program Files\Autodesk), so you usually don’t have write permissions to XSI_SAMPLES.
You need a project to save a scene, so create a new project somewhere where you have write permissions, for example, in your Documents folder.
Then save your scene.
