Ejecting disk issues and freeing memory

Ok, so sometimes the disk gets stuck and I can't find a way to get it to eject. What should I do?
Also, something is taking up space on my macbook pro and I don't know what it is. I deleted unwanted programs, videos, and movies. I still want to free more space. When i click "About this mac" it says 34.22GB free out of 211GB. There is this huge yellow portion that says 61.35 what is that? Thanks.

In Mac Help:
If you’re trying to eject a CD or DVD:
Choose Apple menu > Log Out, and then log in again. Try to eject the disc again.
If you still can’t eject the CD or DVD, choose Apple menu > Restart. While your computer restarts, hold down the mouse button or trackpad button until the disc is ejected.
The Yellow portion is a catch all category for items that do not fall into the other ones. Best way to find what you don't want is to down load from the Internet OmniDiskSweeper (free) and open it. It will show you in a sequential format all you files and the space they are taking.
Ciao.

ByteBuffer.allocateDirect vs. NewDirectByteBuffer and freeing memory

Hi all, I have a very basic question that I'm afraid I couldn't find in any documentation. My question is, when a ByteBuffer in my JVM wraps a direct memory buffer does it try to free that native memory when it gets GC'd? It seems like it would have to do this when I (the user) create it via ByteBuffer.allocateDirect; but if I use a JNI call into NewDirectByteBuffer, I understand that I'm taking responsibility for freeing that memory when I'm finished with it. Both will return true for isDirect(), but in the case where I created the buffer myself and passed it to NewDirectByteBuffer, then free'd that memory myself, will the ByteBuffer object know that it's not supposed to free that memory?
Thanks in advance.

My question is, when a ByteBuffer in my JVM wraps a direct memory buffer does it try to free that native memory when it gets GC'd? Yes, but I have found it does this very slowly. i.e. When the JVM runs low on heap space it will GC before it throws an OutOfMeoryError However for non-heap space this doesn't happen so reliably.

You may be able to break point it to see what it does in your case.
If you are not sure, why not call ByteBuffer.allocateDirect().

Help please, Hard disk issues and HPQ confusion

Hi all,
I have a Compaq N800c EVO laptop, well 2 but thats a story. And I'm having a game with the hard drive.
Until monday my main laptop was an FIC A360, but this Compaq will be taking it's place.
So I have the N800c which came with a compaq stickered 40gig fujitsu MHS2040AT, it boots and works, OS and all. The fujitsu is ATA-100 and oem equipment in the notebook.
The FIC I'm retiring has a retail Hitachi Travelstar 7K100 60Gig hard disk. This works (OS and all) in the FIC but in the N800c nothing, just a flashing cursor on the top left of the screen. The Bios can see it, self tests ok, but won't boot it.
If set to cable select I get the same, If i set it to device 0 it gives a non system disk error.
I thought this was strange so I've also tried 2 Fujitsu MHN2200AT 20gig drives again, no joy. Both had clean OS installs.
I flashed the system Bios up to the latest revision from the support section of the site, tried Hiachis drive config utility to hold the ATA to 66, and tried all of the above again.
I even have a second of these laptops i purchased without a hard disk and almost disgarded as i thought this error was the laptop. Since discovering this all of this behavior is repeatable in the second laptop!
I've read about drive firmware being locked down on IBM thinkpads, is this a similar thing? Where do i get the correct firmware to apply to my drive? to allow it to work with this laptop. Or Where do I get a Bios that isn't prohibitive for the Laptop.
I have written to Hitachi this morning, and now posting here this lunch time
Many thanks and kind regards
Richard

Not so, I've done this on a few machines hence wanting to do it on this one.
At initial boot up it'll discover a whole bunch of new hardware and the items it can't find will become yellow question marks in the device manager. i'm going to have a little play with one of the scrificial fujitsus later and verify either way then i'll report back. I'm fairly confident what i'm seeing is a firmware clash though as there is no logical reason the drive shouldn't load. It should at least go through to some activity, but its almost as if the computer has asked if its in its club, then when the drive says no it refuses to continue. In the bios and hitachis hard drive utilities it tests as ok. As do the two little fujitsus.
IBM thinkpad drives are "ibm'd" in their firmware anyone know of compaq doing this?

Garbage Collecting and freeing memory in JTree

Suppose you have a JTree with a model that takes a lot of memory. after you are finished using the tree you want to free this memory. so you go on and use the
tree.setModel(null) method, hoping everything will be fine. to be extra sure you even set the root to null.
what happens is that the tree view is cleared but the memory isn't.
my conclusion is that somwhere in the tree package there are refrences to the tree root, model or whatever that keeps it from been garbage collected. to make sure my code doesn't keep any refrences to the tree model I am using a very thin class that only instantiates a tree and fills it with data. this class keeps no members, listeners, refrences and so on.
calling system.gc() does nothing.
Is there a simple way to clear memory in a JTree ?
without using weak refrences and other unwanted complexities.

Hi, thanks for the response.The C API version is 6.5.3 or 6.5.4.2, depending on the environment.I'll paste the code in here, but it is completely based on the sample programs so I'm not sure where else we could free up memory (any insights appreciated!):ESS_MEMBERINFO_T *pChildMemberInfo = NULL;sts = ESS_Init();if(sts == ESS_STS_NOERR){ sts = ESS_Login(srvrName, adminUserName, password);if(sts == ESS_STS_NOERR){// set the active dbsts = EssSetActive(hCtx, appName, dbName, &Access);if(sts == ESS_STS_NOERR){memset(&Object, '\0', sizeof(Object));// open the outline for use in subsequent callsObject.hCtx = hCtx;Object.ObjType = ESS_OBJTYPE_OUTLINE;Object.AppName = appName;Object.DbName = dbName;Object.FileName = dbName;sts = EssOtlOpenOutline(hCtx, &Object, ESS_FALSE, ESS_FALSE, &hOutline);if(sts == ESS_STS_NOERR){// get member names from outline, so// this section includes a number of // sts = EssGetMemberInfo(hCtx, // category, &pChildMemberInfo);// calls to query member names.// Then some calls are made to free // these resources:if(pChildMbrInfo){EssOtlFreeStructure(hOutline, 1, ESS_DT_STRUCT_MBRINFO, pChildMbrInfo);}if(pChildMemberInfo){EssFree(hInst, pChildMemberInfo);}EssOtlCloseOutline(hOutline);}}ESS_Logout();}ESS_Term();}

Eject disk instead of eject ipod?

just oneeeeeeee more question
everyone tells me it should say "eject ipod" on the icon in the bottom right hand corner
but it says "eject disk" instead and when i click it, my disk driver thing opens ... I don't want to keep just pulling the chord out .. what do i do?

Okay your IPOD is set to run in disk mode. Read this:
Do Not Disconnect - http://docs.info.apple.com/article.html?artnum=61135
Ejecting the IPOD from ITUnes diconnects it from that software program only. It is still connected to Windows and operating as a hard drive. You must disconnect the IPOD by using the "Safely remove Hardware" icon (Green Arrow) running in the lower right hand tray of Windows.

I have a 1TB WD external hard disk, which suddenly cannot be detected in my system. When i connect the hardisk to the macbook, the disk appears and immediately disconnects with the message "Disk not properly ejected". Any advice ?

verify on another Mac if the same
WD is having issues with mavericks as you can see on the WD forum, did you install any WD software (never do that) when you connected the drive for the first time?
possible issue is a dead SATA bridge card or the new WD firmware w/ Mavericks.
SATA card issue
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD

I did disk utility, and verify disk and it asks to repair the disk using dvd installer...but when i insert the dvd- restart- hold c, it keep ejecting and can't read the dvd....i tried with my friends dvd too, but still fail...mac osx v10.6.7

someone pls help me

Well there is Resolve startup issues and perform disk maintenance with Disk Utility and fsck witch includes step by step instructions to run disk repair without the install disk.
But before doing that, it's a good idea to backup. You may want to troubleshooting your superdrive / disk before hand. if I disk repair fails you may need the disk working to re-install the OS.
Dose the computer read any DVDs? if no, you may want to use Troubleshooting the slot load optical disc drive.

My external HD stopped showing up on my desktop, but shows up in my Disk Utility.. I have tried a disk verify and repair - sometimes that works and completes, sometimes it doesn't. Either way, it wont eject or mount, and still doesn't show up on desktop.

There are no ticking noises coming from the hard drive, and it lights up still, and i have tried replacing the cords, and restarting/shutting down the computer, and have tried it on a mac desktop also - same problem.
Any help would be great!!!

Hard disk partition issue and space issue

Hello i was trying to do a partition on my hard disk on my macbook pro retina. Wen i go to disk utility and try it says i need to repair the disk. I used command r in reboot and repaired but still having issues. When i look at space i get two different space available on macintosh HD. Here are the pictures you will see the space available is different depending what i choose. I am confused. Any help is appreciated. Here are the pics.

When you boot using Cmd-R, you're booting from a hidden Recovery Partition. That partition is using part of the space that is the size difference you're seeing between the Media line (upper picture) and the boot partition line. You can turn on the Debug Menu which shows the extra partitions using these directions.
I'm not sure but I suspect the issue may be that your boot partition is encrypted.

How do I eject a dvd disk that will not eject when I highlight it and click the eject disk in finder, has anyone had this problem?

How do I eject a dvd disk that will not eject after I have highlighted it and clicked the eject disk in finder file menu?

Complements of Kappy:
Try:
1. Restart the computer and after the chime press and hold down the
left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in
your Utilities folder. At the prompt enter or paste the following:
/usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

Re-mounting Ejected Drives and Flash Memory

After using an external drive (both Firewire and USB,) I often eject it to be sure that I do not unintentionally work with directories and files stored on it. To use the device again, I disconnect and reconnect to cause it to be mounted.
Can I re-mount the device with a script or UNIX command? Or some other method which does not require physical action? Advice on how to do this would be greatly appreciated.

Hello Kenichi.Thanks for your reply.
If I eject the disk then it is no longer seen by Disk Utility and thus an external interrupt (power, unplug etc.,) is necessary to reconnect the device and mount the volume(s.)
I now understand that I sould be un-mounting the volume, not ejecting the device to accomplish my requirement of making it's filesystems unavailable.
As you point out mounting a volume can be done with Disk Utility. I was hoping to it with a script or Automator workflow. There are no Automator actions to do this and Disk Utility does not have a scripting dictionary so it looks like I'll have to dig out the UNIX manuals to do this.
Further advice is always welcome.

N86 hard format and restoring / Memory issue

Hello Nokia hello all,
I have an issue in my N86; after a simple restart I got memory crroupted in E:/ and external memory. and the phone doesnot working properly. I did hard reset according to the available instructions but it does not change anything.
currently I caanot store anything in the E:/ drive because I lost it after a few days, and also the external memory is crroupted and does not open.
please your urgent help.
best regards,
Solved!
Go to Solution.

Have you checked whether Nokia Suite upon PC gives you the option to re-install existing device software?
When you say "hard reset" was this *#7370# followed by 12345 (default Nokia lock code unless altered by user) or three key depressed power on reset until Nokia "Shaking hands" logo appeared?
As your N86 supports UDP = User Data Preservation you haven't restored possibly corrupt settings?
Happy to have helped forum in a small way with a Support Ratio = 37.0

Corrupted disk issues between iMacs and Mac OSX Lion

My iMac can't boot up, because it started to fill a black bar at the bottom of the screen and it suddenly disappears. Tried to repair my disk but Disk Utility said "the disk cannot be repaired". So I formatted twice and made a brand new installation, and the same problem returned. I went to the apple support and they said that a bunch of iMacs were having the same issue, and told me to stay at snow leopard until a fix was realeased. Is this normal to iMac self-corruption? Or is just a real Lion problem?

Disposing a jframe, and freeing up memory

Greetings,
I hope this is the proper forum for memory issues.
I have an enterprise database reporting desktop application that I am developing. The GUI application reports on a huge set of data that results in the app taking up to 125 MB worth of memory when fully loaded. There are moments in using the application that all of the data will need to be refreshed entirely, and the JFrame that reports it be reloaded in the process.
I am wondering how to dispose the JFrame and release all of the data associated with it. I use NetBeans to develop my GUI, and so all of the data that is needed for the JFrame is a class variable of the JFrame (so the data can be accessed as it is needed). But, when the frame is disposed, I no longer need anything associated with the JFrame that gets disposed. The Javadoc for Window.dispose() seems to imply that not all of the resources will be released and GC'd when you call dispose, because it says "The Window and its subcomponents can be made displayable again by rebuilding the native resources with a subsequent call to pack or show." which to me says that the data is being remembered and not collected by the GC.
Anyone have any tips for GUIs and memory management? It seems like any GUI app could get pretty large pretty fast if there's no way to release the data associated with the GUI.
Here's the code I've tested that doesn't seem to be releasing the memory (stress tests of closing and re-opening the window multiple times shows the java.exe process eating more and more memory):
    public void reset(){
        this.dispose();
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new PartsDashboard(partNum, dateFrom, dateTo);
        try{
            this.finalize();
        } catch (Throwable t){
            t.printStackTrace();
    }Thanks in advance.

Three things you can always count on in life: Death, Taxes, and AndrewThompson64 telling people to post an SSCCE. =)
Just poking fun.
Anyways, this problem has gone from probably-should-deal-with-soon to critical issue. Here is the SSCCE to illustrate the problem. NOTE: My client is using Windows and I am using Windows, so how this acts on Linux/Mac isn't important to me. Also, a few of my client's machines are not well equipped (512 MB RAM), so they have agreed to up their hardware a bit.
But the big problem, on my end, is that disposed windows DO NOT free up resources once disposed. My program is very data-heavy. I have considered grabbing less data from the database but this would mean the program would have to go to the database more often. The ultimate dilemma of time vs space, essentially.
To explain the SSCCE: There is a main window with a button. If you click the button, it launches another window with a String array that is 500,000 items large (to simulate a lot of data), and a JList to view those strings. Closing the data-heavy child window does not free up the memory that it uses, and if you launch a bunch of the child windows in the same program instance (close each child before launching a new one) then you will see the amount of memory piling up.
Am I doing something wrong? Has anyone else experienced similar problems? Does anyone have suggestions? Thank you.
