Shouldn't this work?

Question

I want to upload the files in the folder on server which the
user selected in the ComboBox. But I cant get it working, any
ideas?
In Flex:
private function startUpload():void {
if (_arrUploadFiles.length > 0) {
disableUI();
listFiles.selectedIndex = _numCurrentUpload;
scrollFiles();
// Variables to send along with upload
var sendVars:URLVariables = new URLVariables();
sendVars.projekt = ComboBox(projektNamn).selectedItem.data;
var request:URLRequest = new URLRequest();
request.data = sendVars;
request.url = _strUploadUrl;
request.method = URLRequestMethod.POST;
_refUploadFile = new FileReference();
_refUploadFile = listFiles.selectedItem.file;
_refUploadFile.addEventListener(ProgressEvent.PROGRESS,
onUploadProgress);
_refUploadFile.addEventListener(Event.COMPLETE,
onUploadComplete);
_refUploadFile.addEventListener(IOErrorEvent.IO_ERROR,
onUploadIoError);
_refUploadFile.addEventListener(SecurityErrorEvent.SECURITY_ERROR,
onUploadSecurityError);
_refUploadFile.upload(request, "file", false);
This in upload.php:
$file_path =
$_SERVER['DOCUMENT_ROOT']."/mockingbird/".$_REQUEST['projekt'];
$file_temp = $_FILES['file']['tmp_name'];
$file_name = $_FILES['file']['name'];
//checks for duplicate files
if (!file_exists($file_path."/".$file_name)) {
//complete upload
$filestatus =
move_uploaded_file($file_temp,$file_path."/".$file_name);
if(!$filestatus) {
$success = "false";
array_push($errors,"Upload failed. Please try again.");
else {
$success = "false";
array_push($errors,"File already exists on server.");
break;
default:
$success = "false";
array_push($errors,"No action was requested.");
return_result($success,$errors,$data);

Totally bogus that a 500GB Wester Dig harddrive made in 2009 would have so many bad blocks.....
What usually produces a bad block, a hard kill of a system?
