Inside my MBP 2011: 50GB Vertex 2: Boot files and Applications 320GB Stock Optibay: EVERYTHING else (desktop, documents, downloads, HOME, etc.) Running Snow Leopard If I download a Word file or Powerpoint file and try to open it (these are downloading to the 320GB), the following error hits me: "Word cannot open this document. The document might be in use, the document might not be a valid Word document, or the file name might contain invalid characters (for example, <>|\"/_)." If I type up a Word file or Powerpoint file and try to save it (to the 320GB), the following error hits me: "Word cannot save this document due to a naming or permissions error on the destination volume" 'Saving to' and 'opening' from the 50GB Vertex 2 works just fine, but I would like to be able to do this from the 320GB instead. I have tried repairing permissions on both drives with no luck, thank you.
