Get name of startup disk JS

Question

I've got an applescript that get's the name of the startup disk using
set macname to get name of startup disk
I'm wondering if the same can be done in a javascript that runs in InDesign CS3....
I need to make the scripts work across platforms and am new to Java Scripting.
Thanks in advance for any feedback.....

Hi Kasyan!
This is a very old thread, but I came accross it while searching for a solution to put the name of my startup disk in front of a file path in the "ancient" notation where the folder hierarchy is represented with a ":" devider istead of the "/".
For all lurkers here:
When exporting to fixed layout EPUB using the epubFixedLayoutExportPreferences in InDesign CC 2014, you sometimes need this "ancient" notation when working on a Mac. In the epubFixedLayoutExportPreferences you can assign an array of file paths to external CSS and JS files. And these file paths are in the notation:
"NameOfTheDisk:NameOfFolder:NameOfOtherFolder:external.css"
Instead of:
"/NameOfFolder/NameOfOtherFolder/external.css"
If you do the folder devider with "/" and the root is simply written as a "/" at start of the file path, the export will fail to include the external CSS and JS files.
See this thread in the Adobe InDesign EPUB Forum for example:
Script EPUB export not including JS/CSS with epubFixedLayoutExportPreferences
So let me thank you for this AppleScript snippet to get the name of the startup disk!!!
I have added some lines of code to get the name of the InDesign app more accurately equal of its version number.
I've tested this on my MacBook with OSX 10.7.5. Hope, that the AppleScript part will not break on later instances of Mac OSX.
Here your code with my small addition:

//Some small addition by Uwe Laubender
var myDisk = GetStartUpDisk();
$.writeln("The name of my start up disk is: \"" + myDisk + "\"");
function GetStartUpDisk() {
    //Get the name of the application for Mac users:
    var myAppName = decodeURI(File(app.fullName).name).replace(/\.app$/,"");
    if (File.fs == "Macintosh") {
        var myScript = 'tell application \"Finder\"\r'
        myScript += 'set myStartUpDisk to get name of startup disk\r';
        myScript += 'end tell\r';
        /* CHANGED LINE: I replaced the original line (now commented out) with a more general approach */
        /* myScript += 'tell application \"Adobe InDesign CS' + ((parseInt(app.version.substr(0, 1)) - 2) + "") + '\"\r'; */   
        myScript += 'tell application \"'+myAppName+'\"\r';
        myScript += 'tell script args\r';
        myScript += 'set value name \"myScriptArgument\" value myStartUpDisk\r';
        myScript += 'end tell\r';
        myScript += 'end tell\r';
        app.doScript(myScript, ScriptLanguage.applescriptLanguage);
        var myStartUpDisk = app.scriptArgs.getValue("myScriptArgument");
    else if (File.fs == "Windows")  {
        var myStartUpDisk = String(Folder.system).charAt(1);
    return myStartUpDisk;
Hm, now the question is: How can I get the name of a disk, that is not the startup disk?
Could one of the AppleScripters here in the forum comment on that?
All the best to you, Kasyan!
