NO disk in drive problem if disk cd/dvd rom drive is empty.PLEASE HELP ME part2

Question

Hi All,
To make it easier to see here it is again. Im realllllyyyy desprate, I have my boss breathing down my neck!!!
I'm working on this problem which doesnt seem to be around anymore. I;ve checked the forums but no recent post has been submited ami out of date. Please help me
The problem is that I need to check that hte user has inserted the CD which is needed to run with the application. So i check the labels of all the drives but if a CD rom or any drive is empty I get the "No Disk in Drive. Please insert disk". If i click cancel it works. How do i get it to go away?????????????.
I even disable the system security which is what was suggested in the past but it still doesnt work.
Here is the code
SecurityManager sm = System.getSecurityManager();
// Disable the Security Manager
System.setSecurityManager(null);
FileSystemView fsv = FileSystemView.getFileSystemView();
fil =File.listRoots();
for (i=0;i<fil.length;i++){
if(found==true)
break;
if((fsv.isFloppyDrive(fil))==false){
if(fil[i].canRead() && !fil[i].canWrite()){
list= fil[i].list();
if(list!=null){
for( j=0;j<list.length;j++){                            
if(list[j].equals("SDBSL_CD")){                                    
str= fil[i]+"SDBSL_CD/";
found=true;
break;
System.setSecurityManager(sm);
Any help would be muchmuch appertiated
Ive noticed that when i do:
SecurityManager sm = System.getSecurityManager();
System.out.println("sm"+sm); it returns null
help!

If it is soooo urgent, then perhaps you could help your own cause by making it easier for the rest of us to read your code... Hint [code] tags are there for a reason.
