Problems with partions..

Hi all,
On my macbookpro I installed successfully winxp and linux to have a triple boot with a chain loader.
the 100gb harddisk was partitionated with diskutil in this way:
boot mac60gb linux 18gb win15gb
Now I wanted to delete win and linux and extend the mac partion to use the recovered diskspace...
from a linux cd I deleted the win and linux partitions
but now I can't extend the mac partion with diskutil:
this is the output of diskutil list
/dev/disk0
#: type name size identifier
0: GUIDpartitionscheme *93.2 GB disk0
1: EFI 200.0 MB disk0s1
2: Apple_HFS MacOsX 60.0 GB disk0s2
and this is what I get if I launch sudo diskutil resizeVolume disk0s2 limits
For device disk0s2 MacOsX:
Current size: 64424509440 bytes
Minimum size: 47659638784 bytes
Maximum size: 64424509440 bytes
Please can anyone help me to avoid a complete format?
Cheers
Alex

hi hyphen, thank you for your reply
I have read on the website that ipartition works only
with the ppc macs so it shouldn't solve my
problem.
Do you think it is possible (and eventually how) to
create a new partition in the empty space?
Thank you again
Alex
Hi Alex, glad your problem got resolved. Just for future reference and anyone reading this post iPartition is now a dual-binary so no worries for Intel Mac owners.

Problem with partion resulting in "One of the source volumes specified has an invalid format and cannot be protected using Windows Backup. Only volumes formatted with NTFS/ReFS can be protected."

We have two new Windows Servers 2012 R2 that I'm trying to set backups on using a script. When I used the -allCritical switch, I get the error specified in the subject. When I look at the partition information using diskpart, I see a 2048 MB partition with
no drive letter labeled as System that is FAT32. I was never prompted to my recollection of what file system to format the partition with. Is it safe to assign this partition a letter, convert to NTFS, and then remove the drive letter?
Thanks

I did. I assigned the drive a letter and ran CONVERT [drive letter]:
/FS. I was really worried during the reboot, but it came up OK, and after it was back online, I removed the drive letter.

Fafter upgrading to mavericks,I had problems with windows 8.1, so deleated partion to start over. Everthing went fine until The fact I was using an upgrade disc instead of a bootable version. Now everthing is loocked up and none of the hotkeys work

after upgrading to mavericks, I had problems with windows 8.1. I deleated the partition to start over. Upon try ing to reinstall 8.1 everthing locked up. I had an upgrade disk instead of bootable. Now every time I turn the computer on "it asks for bootable media"; none of the hot keys work to get back eo mac os

You mised the last part where none of the hotkeys are working,neither options nor "X" it goes ms 8.1 boot up and asks foe a bootable disc. I am about to pull the HD put it into a case attach it to another computer and delete the file

Problem with A300, Ask for help

Hello from Bulgaria!
In the beginning I want to apologize if I bother you at the wrong place. This was the only place i found in all your sites at "Contact us" menu. If I'm in mistake please redirect me to the right e-mail or topic.
I have extremely big problem with one of your products, and I'm afraid I can't solve him without your help. Few months ago I bought a laptop witch exact model is TOSHIBA SATTELITE PRO A300 - 1GQ. Model No.: PSAG1E - 00900NF3, Serial No.: 88549776Q. If you need another information I can tell you everything. Badly i got serious virus and the situation reach fall windows start. I know about integrated Toshiba Recovery and I used it. Windows Vista was successfully installed but the partion was not formated. Some of the system files was still corrupted and I resorted to Toshiba DVD comming with the laptop. I ran it, there was no problems until I saw Windows XP logo. I was pretty surprised because I expected Windows Vista like original one which came with the laptop from the shop. Another problem was that that installation formated whole HDD including partitions different from C:\ with Windows system files. All of my data is gone without I could be able to do something. However, th
e question is that I need Windows Vista very badly and I dont want XP. I tried to use hidden partition with Toshiba recovery again but I cant no longer access it. So I left with original XP with drivers integrated with it. The problem is that I need Vista with integrated drivers. It wouldn't be hard also if I found that drivers in your sites. Nowhere in your sites with download I could find the exact model to take it. The nearest was A210 which I think is pretty far from mine.
And it the end I ask for help if you can tell me where to download the needed drivers or anyway to put Vista back. Preliminary I thank you and I apologize again for the disturbing. I need that information badly and I don't know where I can get it from. At least show me valid e-mail to contact with Toshiba Support.

Problem with replicated partitioning between two BSO db's. version 9.3.0.1

Hi there,
I have a problem with partitioning between two BSO db’s.
I created the partition, it validates and I made an export for the partion definiton(xml file).
Everything is fine if I set this partition up as transparent partition.
This means I can see the data from the src in the trg db as ecpected.
But when I change over to replicated (what in fact I want to do) nothing happens for the trg site - there are still no data. (Yes I have choosen Update all cells.)
I got no error in any way neither AAS nor in the app logs of src and trg.
(Mayby this it important: one src-dimension is mapped to void for the trg.)
Can anyone give me a hint or even confirm this behaviour ?
Thank you in advance
Andre

It sounds like you are doing it all correctly. One thing you might try just to be sure you are not getting any data in the target database is the following:
1) clear the target database
2) Run the replication for all cells
3) Run an export of all data on the target database
See if you get anything in the export file, maybe you are getting some of the data or possibly it is a rollup issue. Just a thought.

Having problem with hp computer freezing up and rebooting? have already updated video drivers

I having problem with HP Slimline Desktop with AMD Vision, freezing up and rebooting, and will sometimes show horiztonal lines across the screen, making screen unreadable. Have had problem for a few weeks, I have already checked with HP tools hard drive and video display both check out, and have I restored the system back to its orginal version by using partion drive and, none seems to help get rid of the freezing and rebooting of PC. Any thought what need to look at?

Can you locate a product number on the system that is freezing??

Weird install problem with OS X, please help!

I've been upgrading a friend powerbook firewire 400Mhz G3, we installed 1GB of memory and put in an 80GB HD. I partioned so that OSX can be on the first 8GB, put 9.1 on the second parition of 7GB, upgraded the firmware, and i think i have tried just about everything i could find here on the discussion board.
I have several versions of X including the first version, panther (retail), and tiger (borrowed, on DVD). tiger and the original version get as far as installing, then go into kernal panic (you must restart right now.....etc). 10.2 just gts to the apple screen then a white jagged bar pops up.
i'm at a loss. i really don't know what i try to make this better, any help is greatly appriciated!!!!
oh, and the memory seemed fine when her original 6GB drive was in there, which had tiger installed.
j

jhw1,
I will just run by you some potential causes for your problem and hope that one hits the target.
- I will ask, out of curiosity, why you are making an 8GB partition for OSX? This limitation applies only to the older Wallstreet powerbook. There is no need to partition the HD unless you have a specific reason.
- Since the HD is new, and you still want to run Classic and also boot 9.x, make sure you install the MacOS 9 HD driver, an option in OSX's Disk Utility when erasing an HD, or go ahead and install OS 9.x first...this will automatically install the OS9 HD driver. If you install OSX first on a clean HD without installing the OS9 HD driver, MacOS 9 will run fine in Classic under 10.x but 9.x will no longer boot.
http://docs.info.apple.com/article.html?artnum=107285
- The Pismo has a history of failing DVD-ROM drives and usually the CD-side starts acting up first. If you have access to another Pismo or Lombard, swap drives and try the install. If you have access to a FireWire CD-RW, you can also boot OSX CDs using it.
- Reset the PRAM if you have not done so.
- You may have dirty or bad CDs; carefully clean or try others.
- You mentioned the 'book ran fine with 1GB of RAM and running Tiger on a 6GB HD, but probably the 1GB was installed after Tiger was on the HD. There is the remote possibility that the RAM is problematic when running the installers. A Wallstreet, for example, often has problems installing with 512MB, but if one 256MB module is removed, the install goes fine, then the RAM is reinstalled.
If this were my 'book, I would try this:
1. Disconnect all peripherals and reset the PRAM.
2. Boot to the 9.x CD > use Drive Setup to repartition the HD (if you wish) > install 9.x to make sure the HD, RAM, etc, are good-to-go.
3. Boot to your OSX CD and see how the install proceeds. If it fails, it may be a problem with the optical drive and/or CDs. Try the options I mentioned earlier.
4. If you wish, remove the top memory module and try the install again. If successful, reinstall the module.
5. If there is no workaround for the optical drive, you might try installing via FireWire Target Disk Mode. The 'target' will be the Pismo's HD on the desktop of the 'host' computer and you will boot the host computer to the OSX CD and select the Pismo's HD as the destination.

OneKey Recovery 6.0. Problem with back up operating system from recovery cd'ies

Hello, i have problem with back up operating system from recovery cdies.
When i acceped start button to backup partition system i get an alert "space not enough"
I had linux before and i whant change it to windows back. i deleted all ext partitions. I have all unlocated space.I shouldnt have problems.
Please help me

I would use something like Partition Magic or Acronis Disk Director to first create a FAT32 partion for your C: Drive where your OS will go and be sure to leave 10GB or so unallocated for the secondary FAT32 Partition where your "factory image" will go.
You then create a Logical Drive with the unallocated space and make it hidden (PM or ADD will do this). Install your OS (preferably Windows XP if you want less problems) and then after you have setup everything the way you want (drivers, applications, etc), then use Acronis True Image to create your "factory restore" image on the hidden partition and activate the Startup Recovery Manager.
This is the way I do it and it works like a charm!

A problem with threads

I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
Thank you in advance,
Lefty

This was one solution from the socket programming forum, have you tried this??
public Thread MyThread extends Thread{
     boolean active = true;
     public void run(){
          ss.setSoTimeout(90);
          while (active){
               try{
                    serverSocket = ss.accept();
               catch (SocketTimeoutException ste){
               // do nothing
     // interrupt thread
     public void deactivate(){
          active = false;
          // you gotta sleep for a time longer than the
          // accept() timeout to make sure that timeout is finished.
          try{
               sleep(91);
          }catch (InterruptedException ie){
          interrupt();
}

Problem with Threads and a static variable

I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
Code functionality:
A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
The problem as far I understand is:
Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
Thanks,
B.D.
Code:
private static volatile boolean bChanged = false;
private static Thread objMainProcess;
   protected static void Init(){
        objMainProcess = new Thread() {
            public void run() {
                while( objMainProcess == Thread.currentThread() ) {
                   GetState();
        objMainProcess.setDaemon( true );
        objMainProcess.start();
    public static void initStatusTimer(){
        if(objTimer == null)
             objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
                public void actionPerformed( java.awt.event.ActionEvent evt){
                          SetState();
    private static void SetState(){
        if( objMainProcess == null ) return;
        synchronized( objMainProcess ) {
            bChanged = true;
            try{
                objMainProcess.notify();
            }catch( IllegalMonitorStateException e ) {}
    private static boolean GetState() {
        if( objMainProcess == null ) return false;
        synchronized( objMainProcess ) {
            if( bChanged) {
                SendMessage();
                bChanged = false;
                return true;
            try {
                objMainProcess.wait();
            }catch( InterruptedException e ) {}
            return false;
    }

Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
Again as you said, There is a reason I can't call sendMessage() inside setState().
The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
Thanks,
B.D.

Problem with threads running javaw

Hi,
Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
troy.

troy,
Try and post a minimum code sample of your app which
does not work.
When using javaw, make sure you redirect the standard
error and standard output streams to file.
Graeme.Hi Graeme,
I dont understand what you mean by redirection to file? some of my code below.

Problem with threads and camera.

Hi everybody!
I've a problem with taking snapshot.
I would like to display a loading screen after it take snapshot ( sometimes i
have to wait few seconds after i took snapshot. Propably photo is being taken in time where i have to wait).
I was trying to use threads but i didn't succeed.
I made this code:
display.setCurrent(perform);
        new Thread(new Runnable(){
            public void run() {
                while((!performing.isShown()) && (backgroundCamera.isShown())){
                    Thread.yield();
                notifyAll();
        }).start();
        new Thread(new Runnable(){
            public void run() {
                try {
                    this.wait();
                } catch(Exception e) {
                    exceptionHandler(e);
                photo = camera.snapshot();
                display.setCurrent(displayPhoto);
        }).start();This code is sometimes showing performing screen but sometimes no.
I don't know why. In my opinion performing.isShown() method isn't working correctly.
Does anyone have some idea how to use threads here?

Hi,
I've finally managed to work this fine.
The code:
       Object o = new Object();
       display.setCurrent(perform);
        new Thread(new Runnable(){
            public void run() {
                while(!performing.isShown()){
                    Thread.yield();
               synchronized(o) {
                  o.notify();
        }).start();
        new Thread(new Runnable(){
            public void run() {
                try {
                    synchronized(o) {
                       o.wait(1);
                } catch(Exception e) {
                    exceptionHandler(e);
                photo = camera.snapshot();
                display.setCurrent(displayPhoto);
        }).start();

Problem with threads hanging

We have a problem where our application stops responding after a few days of usage. Things will for fine for a day or two, and then pretty quickly threads will start getting hung up, usually in places where they are allocating memory
We are running WebLogic 8.1 SP2 on Sun JDK 1.4.2_04 on Solaris 8 using the alternate threading model and the -server hotspot vm. We are running pretty much the same code that we had no problems with under WebLogic 6.1 SP4 and Sun JDK 1.3.1.
A thread dump usually shows that some or all of our execute threads are in the state "waiting for monitor entry" even though they are not currently waiting on any java locks. Here is a sample thread from the thread dump (we have ~120 threads so I don't want to post the full dump).
=============================================================================================

String.java line 1446 for this jdk allocates a new String object, and all the other threads in this state also are creating new objects or arrays, etc.
We've done a pstack on this process when it's in this state, and the threads that are in the "waiting for monitor entry" that look like they're allocating memory are all waiting on the same lwp_mutex_lock with some allocation method that's calling into the native TwoGenerationCollectorPolicy.mem_allocate_work (see pstack output below for the same thread as in the thread dump above)

Also when it's having this problem, the "VM Thread" is always using a lot of processor time. We did a couple of pstacks today while it was having this problem, and this thread was stuck in the ONMethodSweeper.sweep for over 15 minutes when we finally killed the server.

Has anyone ever seen anything like this? I'm trying to figure out if this is caused by something we're doing, or something relating to our environment and jvm options. Any ideas?

Thanks for the reply - I'm testing our app with the +UseConcMarkSweepGC now in our test environment to make sure it doesn't cause any problems there. Unfortunately the only place we've had this problem is on the production server, so it's extra difficult debugging this.
We're using the following memory options:
-ms512m -mx512m -XX:NewSize=128m -XX:PermSize=192m -XX:MaxNewSize=128m -XX:MaxPermSize=192m -XX:SurvivorRatio=8and the following debugging options, as we've also been seeing OutOfMemoryErrors ( see http://forum.java.sun.com/thread.jsp?forum=37&thread=522354&tstart=45&trange=15 )
-verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGCBTW, which c++filt version and options are you using? Our Solaris boxes only seem to have the GNU version installed. I was trying to run that on some of the other stack traces and wasn't getting anywhere, and didn't know if because it was GNU version wouldn't work on something compiled with the Sun compiler.
Thanks!

Problem with threads and ProgressMonitor

Dear Friends:
I have a little problem with a thread and a ProgressMonitor. I have a long time process that runs in a thread (the thread is in an separate class). The thread has a ProgressMonitor that works fine and shows the tasks progress.
But I need deactivate the main class(the main class is the user interface) until the thread ends.
I use something like this:
LongTask myTask=new LongTask();
myTask.start();
myTask.join();
Now, the main class waits for the task to end, but the progress monitor don`t works fine: it shows only the dialog but not the progress bar.
What's wrong?

Is the dialog a modal dialog? This can block other UI updates.
In general, you should make sure that it isn't modal, and that your workThread has a fairly low priority so that the UI can do its updating

Problems with partions..
