Need help freeing up space

I recently purchased time capsule as I need to free up space on my disc. I connected it as the instructions says. I have backed my information up but just recently I tried using Photoshop and a message came up saying I didnt have enough disc space. I thought that time capsule would help with this problem. Have I set up my time capsule wrong? Is there a way I can put everything from my existing internal hard drive onto my time capsule so I can have more space?

If you mean you want to remove things from your internal HD, and depend on Time Machine keeping copies of it all on your Time Capsule, don't! Time Machine will delete it's copies of anything that's no longer on your system, sooner or later. See #20 in the Frequently Asked Questions *User Tip,* also at the top of the +Time Machine+ forum.
Time Machine is a backup app, not an archiving app. They may sound similar, but they are very different.
You can, however, copy/move things from your internal HD to your Time Capsule, but not via Time Machine. That will, however, give you two problems:
Wireless access is much, much slower, so anything using the data on the TC will be considerably slower.
Your data is still not backed-up. When your internal or Time Capsule HD fails (and they all do, sooner or later), you risk losing everything.
Your best bet is probably getting a larger internal HD, with room for everything.
Second best is an external HD you can connect directly to your Mac for some things that won't fit inside. FireWire 800 is fastest, FireWire 400 next, and USB is slowest.
Then let Time Machine back up everything to your Time Capsule.

Start up disk full need help freeing up space.

My start up disk almost full. Shows 137 GB in "other category" Have been able to locate 75 GB but not 137GB. what makes up "Other"?

First, empty the Trash if you haven't already done so. Then reboot. That will temporarily free up some space. According to Apple documentation, you need at least 9 GB free on the startup volume for normal operation. You also need enough space left over to allow for growth of your data. Use a tool such as OmniDiskSweeper to explore your volume and find out what's taking up the space. Proceed further only if the problem hasn't been solved. ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To really see everything, you have to run it as root. Back up all data now. Launch the Terminal application in any of the following ways: ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. After installing ODS in the Applications folder, drag or copy — do not type — the following line into the Terminal window, then press return:sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
I don't recommend that you make a habit of this. Don't delete anything while running ODS as root. When you're done with it, quit it and also quit Terminal.

Need Help with Java Space Invaders Game!

Hi, im new to these forums so forgive if i dont follow the right way on laying things out. Im trying to create space invaders game but im stuck when im trying to create multiple aliens/ invaders. I have a class called Aliens (which is the invaders), and i can create an instance of an Alien. But when I try to create multiple instances they are not showing up on screen. I am not getting any error message though (which im hoping is a good sign, lol).
GamePanel is where all the action is and Alien is the alien (invaders) class.
Here is the code:

Newbie Needs Helps With Storage Space

I just recently recieved an ipod for Christmas. My biggest problem is I have an old computer without a lot of space. How do I upload my CD collection without completely maxing out what left of my hard drive?? I don't have any nifty USB portable hard drives or anything. I guess the same question goes for all my downloaded music..
How can I just keep music on the ipod and not on my computer??

You need to manually manage your songs.
Here's how:
http://docs.info.apple.com/article.html?artnum=61148
VERY IMPORTANT:: Make sure your music is backed up to some other external media. CD, DVD, external HD, something! Especially your purchased music, if any.
Having your music only on your iPod is VERY RISKY. There may come a time when your iPod has trouble and will need to be restored. It may also get lost, stolen, dropped, etc. If you only have your music on your iPod and something happens to it... your music is gone.

Need help with white spaces/halos when creating PNG

I'm using Illustrator CS6 on Windows 7. I'm trying to create some pushpins that will go on an online map. I've created the graphic in Illustrator and everything looks nice and sharp. My problem is when I try to convert this .ai file to png. The ai file is set up on 8.5 x 11 artboard with the graphic taking up the whole artboard; the final size of the png needs to be 20x34 pixels at 72 dpi.
I've tried both Save for Web and Export but no matter what I do, when I open the png in Photoshop, there is a white space between the grey pushpin and the black stroke as well as around the outside of the S. No matter what I've tried, I can't get rid of these unwanted white spaces/halos. Is there a setting I'm missing somewhere? The large image below is how it looks in Illustrator; the small image is the png opened in Photoshop. How can I get the small png to be as crisp as the large ai file? Thanks.

mc-mark,
Are you sure the artwork is contained within whole pixels on the Artboard?
One way to obtain that is to move the artwork so that the Transform panel tells you that the X and Y values of the lower left corner (or centre or something else) are whole pixels/points; another way is to tick Align to Pixel grid in the Transform panel, but I am afraid that may distort the artwork when used at this stage.

Need Help With Disk Space Issue

I am trying to free up some disk space on my MacBook Pro. Here is what I have in terms of usage of personal files:
Music: 24.7 gb
Pictures: 9.92 gb
Documents: .379 gb
Applications: 9.25 gb
This totals 44.249 gb
My capacity is listed as 111.47 gb. The problem is that I am showing only 11.96 gb available. I don't understand why there is so much gab between what is listed above and the capacity. I realize the System files, Application Support, etc. use a fair amount, but it still seems like I should have more space. I have run Onyx to clear caches, optimize, etc., and that has helped, but only marginally. Are there large files somewhere I am not aware of? I have an iDisk, but I have iDisk Synching off, so there should not be a copy of it on my computer, unless tere is an old oe lurking somewhere. Thanks a lot for any suggestions.

I'll give a very plain answer :P
My Movies folder has a 10 gb size, my Library folder has 5.83 gb, my root Library has 10.89 gb, my System folder has 4.2 gb. I believe there is much more than the basic folders that eats your HDD away.
I don't know if my folders size are normal, but I do know that adding only your basic folders won't give you the real amount of disk used. In my case I have 20.92 gb of space. I would also look the size of the Downloads folder and the Mail folder (in your home/Library/Mail I have 3.5 GB in one account only!)
Hope this helps!
One last thing, not so long ago I saw a post about someone who found a file that was huge, the file was because he let the computer working overnight testing if it ran correctly by letting chess computer vs computer play all night. The game created an enormous file (I believe it was the nbook.db file in username/Library/Application Support/Chess/)
OR... use what Matt Clifton recommends jajaja... seems like a better idea :P

Need Help Recovering Hard Drive Space on Disk Utility

I recently wanted to resize my Boot Camp hard drive partition as I did not need it to be 194 gb. In the process I screwed something up and now that space that was once my Boot Camp Partition is now "free space." My Mac Partition still says that I have 305 gb left and I am unsure how to expand this partition to get back that "grey" space. I've tried using Boot Camp Assistant, starting with Command+R after the "chime," and restoring my OSX (not completely however).
I need help in getting back this missing space. It seems that I have looked everywhere and although people seem to have a similar issue I can't figure it out.
Would restoring Mountain Lion completely by using a USB jump drive solve this problem? I have an external hard drive that uses Time Machine to back up my MacBook so a complete restore shouldn't be an issue.
Any advice would be greatly appreciated!
Thank you!
P.S. This is what my disk utility currently looks like...

You can try to use Boot Camp Assistant to completely remove the Windows partition but it might not work.
Simple fact is once you setup a Windows partition you can't fool with it at all, that is unless you use some add on program specifically designed to do that on a Mac computer. If you need to resize the Windows partition you first need to use BCA and remove the partition completely and then recreate it at the new size you want and reinstall Windows.
You might have to use Time Machine and backup your Mac partition then repartition the complete drive and then restore from that Time Machine backup. Then setup the Windows partition and reinstall Windows.

Need more hard drive space. Help with install WD My Book Studio 1TB EHD.

My MacBook Pro has no more disk space. I'm not tech savy so I'm hesitant to install Western Digital My Book Studio 1TB purchased. I read somewhere not to install the smartware that comes with this external drive because it might cause problems when running Time Machine. I want to move my photos on to EHD to free up space and start up Time Machine. Is there anything I should do first before attempting this. I have not upgraded to Lion yet should I do this after freeing up space and setting up Time Machine. I'm wondering if it will ask me questions during process that I won't be sure to accept or not. I'd appreciate any help or tips.

Do not install any software from WD. Prep the drive as follows:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

Can I and if so, how do I move the whole of iTunes from my computer to my external hard drive? I have absolutely no space left on my computer and desperately need to free up space! Many thanks for help:)

How do I move iTunes completely off my computer and onto my external hard drive? I have no more space on my computer and need to free up space quickly! will iTunes work from external hard drive only? many thanks :)

With iTunes closed, copy (safer if you don't yet have a backup) or move the entire iTunes folder from <User's Music> to X:\ as X:\iTunes (where X is the drive letter of the external). Press and hold down shift as you click the icon to start iTunes, keep holding shift until asked to choose or create a library, click choose, then browse to and open X:\iTunes\iTunes Library.itl.
Note that changing the advanced preference for the media folder location doesn't change where iTunes expects to find existing content. Moving the library in the way outlined above however will work.
You should think about backing up your library to another external drive or network share.

Need help with the "Erase Free Space" disk utility

When I use Disk Utilities to Erase Free Space (I use the single zero mode) I get a message telling me,
"Your Startup Disk is almost Full,
you need to make more space available
on your startup disk by deleting files."
This occurs about 90% of the way through the process (based on where the blue bar is at the time) during the "Creating Temporary File" portion of the process. I know from past experience that I will remain in this portion of the process forever unless I press the "Skip" button to complete the process.
My questions,
1. What is the startup disk and why is it full?
2. What should I do about the Your Startup Disk is Almost Full warning?
3. Is my computer actually talking about "regular" disk space (I currently have about 9GB of 80GB free but have seen this warning with 30GB available as well).
4. When I press "Skip" and the blue bar continues to complete the process, have I actually erased free space?
PBG4 15" 80GB HD 1GB RAM Mac OS X (10.4)

The Disk Utility does the erase by creating large temporary files, writing to them, then deleting them. While doing this, OSX may notice the lack of free space on the disk. This is normal, but could cause problems if you are also running some applications that want some disk space. If you let if finish, it should delete the temporary files and free the disk space.
I prefer to run the Disk Utility from the Tiger install disk when doing a Verify, Repair, or Erase Free Space on my boot disk, so I know I won't be interfering with anything running.

There is no more space for virtual disk ServerName_2.vmdk. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session.   Time: 30/05/2014 1:16:20 AM

Recently, our mail server crashed at about 7pm one night, with the error 'There is no more space for virtual disk ServerName_2.vmdk. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session.'
When we click Retry, the server starts up OK.
There are no snapshots listed in Snapshot manager for any of the virtual machines on the host.
There is also free disk space available on the host and for the VM with the disk errors.
This happened at least three more times, often at bad times. Each time, we were able to click 'Retry' and the disk/system would allow the VM to start-up successfully.
I checked the Forums, the VMware support articles and the internet as I had not seen this problem before. I have completed the VSphere 5.1 - Fast Track course and this issue was NOT covered in the training.
Most of the advice on-line and even that on the VMware web-site was pointing to snapshots being the cause of this issue. There are no snapshots enabled and I cannot see evidence of snapshots ever being used.
- We are running VMware vsphere (5.1.0) and there are (were) 4 virtual machines running on the ESX host. We are using the free version of VMware/ESXi.
- The Hard disk types we are using for this Virtual Machine are 'Thin Provisioned'.
- There are 4 [Thin Provisioned] Hard Disks for this virtual machine.
- There are 6 CPUs
- There is 20GB of RAM (memory)
- The VM is running Windows Server 2008 R2 as the guest/VM operating system. It is an Exchange 2010 SP1 mail server. There is plenty of available disk space on all the drives. The [Exchange] log files are cleaned out regularly (automated).
I decided to move one of our non-critical servers off this host and on to another host to see if this helped the problem. This took quite some time, as we are not using HA or vmotion, nor do we have VCenter Server...nonetheless, I finally managed to get the non-critical server on to another host (n.b. This was a much smaller machine with less virtual resources assigned to it).
After moving the non-critical server off this host, we decided to monitor the Host and see if the issue resolved itself.
I checked the host about 6-10 times a day, from first thing in the morning till last thing at night - monitoring the performance of not only the Virtual Machine, but the ESXi host also.
There were no adverse performance issues. The only thing I did note, was in the Summary page on the ESX Host, under Storage, was If I right-clicked on the datastore and clicked refresh, then the free disk space would drop (ie from 140GB to 125GB).
After monitoring the host and VM for about 2 weeks, we did NOT have another instance of the above error.
Sorry for the long winded post, but I wanted to give as much detail given this error has been raised before and snapshots are usually blamed as the cause.
My question is this:
If the ESX host had plenty of available disk capacity and there were no snapshots enabled on the VM (or any other VM's on the same host), then why did our Virtual machine crash with the error that 'there is not more space for virtual disk Servername_2.vmdk'?
How do we prevent this issue from happening if we don't know the underlying cause?
I would greatly appreciate any advice or suggestions.
If I have not provided enough info on the specs or environment, please let me know and I will provide more information.
Thanks all,
Kurt

The type of storage is really based on your requirements, and your ability to withstand downtime.
iSCSI as you are using with a NAS such as Synology or QNAP. NAS Selector - Support - Synology - Network Attached Storage (NAS)
I wouldn't use iSCSI for Exchange or any database. It's a bit slow.
Do you have a single physical host? Then I'd probably to an external direct attached storage. This would be a card inserted in your host server that gives you multilane SAS/SATA connectivity (www.techcable.com/SAS-SATA/SAS-SATA.pps) and an external disk enclosure/array.
For multiple hosts to a single array, I recommend a fibre channel connection to a FC capable switch, and on to a FC connected array.
We used to use a HP P2000 (on old G1), but it's since been retired. Worked pretty well once firmware was upgraded. http://www8.hp.com/us/en/products/disk-storage/product-detail.html?oid=4118559#!tab=features. They can be connected via iSCSI, Fibre Channel or 6GB SAS so they are flexible and reasonably priced.
Recommendations:
     Use RAID 6 with your large disk arrays. With large disks there is a measurable failure rate when rebuilding a failed RAID5 array based on MTBF.
     Use smaller 15K disks in RAID 0+1 for speed on databases/Exchange.
     Use slower 7.2K disks in RAID6 for file storage.
We are a small hospital and we have 3 VMware servers with dual CNA (FC and Ethernet in a single twinax cable) connections to 2 redundant Cisco Nexus 5K switches and then 4 Fibre Channel connections to an EMC VNX 5300. It's extremely fast with about 50 virtual servers, but was quite an investment. One thing we don't have to worry about is down time. If there ever is an equipment failure, we have redundant everything, including power split between two UPSs.
Our VNX has 3 tiers of performance. 3 100GB SSD "Fast Cache" in RAID 1 with hot spare, to keep the most used data ready, but it's not really a tier, however one could be built utilizing the same disks. A second tier is performance tier with a 8 600GB RAID 0+1 and hot spare. The third is a bunch of 7.2K 3TB disks in RAID6. The VNX autotiers, placing data on disks depending on where it's needed. The volumes are sliced and diced automatically in the background to make this happen and we never have to touch it. I used a demo of Solarwinds Storage Manager to monitor performance for a while and the utilization was always low, meaning all data access was fast, througout the day.

I need to erase free space on my hard drive. But when I am in disk utility the format and name are pale as is the erase free space button so I cannot erase free space.

My start up disk is full. I have been through my computer and erased a lot of music and video to free some space. I then went to disk utility to erase free space and find that the erase free space button is pale and therefore won't work. Nor can I select or deselect MacOS extended journaled.
Advice please?!

Recovering Disk Space
If you have less than 20% disk space then it is time to roll up your sleeves and search for what you can delete and what you can offload to another disk.
If you have less than 10 GB you definitely need to delete or offload some files or purchase a lager disk or SSD (see below). You may want to maintain at least 20 GB of free space so when your disk starts filling again it will have some room before it hits that 10 GB mark again. More headroom is better. If you let the space fall much below 9 GB you might not be able to boot your machine.
Initial easy steps to gain disk space:
- Delete all files in the Downloads folder.
Empty the Trash.
- Start iPhoto.
Empty its trash.
Restart.
- Restart in Safe Mode:
Restart the computer.
As soon as you hear the chime press and hold the right shift key.
Be patient. Hold it down until you see the Apple icon.
Empty the trash.
Restart in normal mode.
- Delete "Recovered Messages", if any.
    Hold the option key down and click "Go" menu in the Finder menu bar.
    Select "Library" from the drop down menu.
    Library > Mail > V2 > Mailboxes
    Delete "Recovered Messages", if any.
- Empty the Trash.
- Restart.
- Re-index your system disk (Macintosh HD):

Time Machine Snapshots:
If your disk is 80% full that is normal. Time Machine uses up to 80% of the disk space for local snapshots. To get rid of these snapshots simply plug in your Time Machine backup drive and run a backup. See About Time Machine's 'local snapshots' on Mac notebooks: http://support.apple.com/kb/HT4878 and What are Local Snapshots? http://pondini.org/TM/30.html .
If you are concerned that the “Other” category of disk usage is taking too much space and for information on deleting files then look here: https://discussions.apple.com/docs/DOC-5142
Backup:
Run a Time Machine (or other) backup since you are about to delete and move files and you may need to recover from any inadvertent mistakes or decisions. You will need one external hard drive for your Time Machine (or other) backup and a second if you plan to offload some files. (See suggestions for where to purchase hard drives at the end of this message.)
For more about backups:
Time Machine Basics: http://support.apple.com/kb/ht1427
Most commonly used backup methods:
https://discussions.apple.com/docs/DOC-3045
Methodology to protect your data. Backups vs. Archives. Long-term data protection:
https://discussions.apple.com/docs/DOC-6031
Deleting files:
Then use the free application OmniDiskSweeper http://www.omnigroup.com/more to explore your volume in descending order by size so you can attack the problem from the top down, deleting the largest unwanted files first. Delete with caution and do not delete any system files. Remember to empty the trash after trashing the files.
Additional reference on freeing disk space:
http://pondini.org/OSX/DiskSpace.html
Offloading files:
Consider moving some of the no-often-used large files or directories to an external disk. Use ODS again to find them. As noted above this will be at least your second hard drive. Your first one(s) is/are for your Time Machine (or other) backup(s). Do not offload files onto a Time Machine disk.
Format the second drive as Mac OS Extended (journaled). Using OWS to find large files/folders and copy them from the system drive to the external hard drive and delete them from your internal drive.
Then  > System Preferences > Time Machine > Options… > Remove the offload HD name from the exclusions list.
Now both your system disk and your external offload disk will be backed up onto your Time Machine disk.

Hardware — Bigger disk/SSD:
If your system has upgradeable storage then if you are still tight on disk space consider larger storage. If you have a disk consider replacing it with a one TB disk. Check out a one terabyte HGST 7K1000 7200 rpm, SATA III drive from OWC http://eshop.macsales.com ($100). If you have an SSD consider increasing its capacity to 240 or 480 GB. A standard 240 GB SSD would cost from $200 to $280. See OWC and Crucial: http://www.crucial.com/ for options. OWC sells 120, 240 and 480 GB SSD upgrades for MacBook Airs. A 240 GB upgrade costs $265.   http://eshop.macsales.com/shop/SSD/OWC/ . If your Mac is under warranty or AppleCare replacing the SSD will void the warranty.
