When I will transfer or delete a large file , my system too slow work even for a few seconds to lock it!
It is very annoying..
I got in Google Search But I not find use...
Sorry. My English is very bad
I encountered your problem myself, when transferring large files via usb. The desktop GUI would be virtually locked up and frozen, keyboard response was very slow. I would hit ctr + alt + f1 to swith to a terminal and I would have to wait 60 seconds or more for the keypress to be recognised. I believe its a bug in the linux kernel somewhere, but I can't recall exactly where I read it.
-edit-
I think this is the thread..

One suggestion, among many, was to disable 'usb legacy support' in BIOS. It worked for some, but not for everyone.

When I format hard disk while installing windows it shows an error?

When I format hard disk while installing windows it shows an error and says that windows can't be installed to this hard disk, but I have installed windows before. How can I install windows?

You are getting this message because you are trying to create an iCloud account on a PC by signing with your Apple ID. You can only sign into an existing account on a PC. You first have to create iCloud account on an iOS device (iPhone, iPad or iPod Touch) running iOS 5 or higher, or on a Mac running OS X Lion (10.7.5) or higher. After creating your account on one of these devices you will then be able to sign into the account using this ID on your PC.

I have an iMac 5.1 with Mac OSX 10.6.8 and 2 GB memory and an L2 cache of 4 GB. lately I have been receiving error messages of " start up disk almost full; please delete files." is the start up disk the same thing as the hard drive?

I have an iMac 5.1 with Mac OSX 10.6.8 and 2 GB memory and an L2 cache of 4 GB. lately I have been receiving error messages of " start up disk almost full; please delete files." is the start up disk the same thing as the hard drive? I opened the hard drive and from the column on the left of the menu I've selected "search for" and under that " all images" then "all documents" I've deleted a few files from each. Are documents and images that I have deleted from here also deleted from the folders on my desktop?

You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Delete any other mail in your Junk folders. Also, look through your Sent Mail to see if there is anything that can be deleted.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

Getting eroor while copying and deleting user

Hi All,
I am unable to copy and delete users from one client, we are in ecc6.0. i am getting the following error while copying and deleting. the error is
NUMBER_GET_NEXT AENDBELEG INTERVAL_MISSING.
Please help me in this regard,
thanks,
praveen

Hi Praveen,
Implement the program correction to ensure that the system issues the correct error message.
Manually create the missing interval.
You can use error message CD 121 to enable you to identify the error more accurately. Depending on the additional information, the status is as follows:
OBJECT_MISSING : The entire AENDBELEG number range object is missing and must be created.
INTERVAL_MISSING: Number range interval 01 is missing and must be created.
INTERVAL_NOT_INTERNAL: The definition of number range interval 01 is incorrectly set to 'external number assignment'. Delete the 'external' selection in the interval definition.
Check the definition of the AENDBELEG number range object in transaction SNRO:
Object name:   AENDBELEG
Short text:    Change documents
Long text:     Number Ranges for Change Documents
To-year flag:                        Do not select
Number length domain:                 CHAR10
No interval rolling:                  Do not select
Number range transaction:             SCDN
Warning %:                            10.0
Main memory buffering:
No. of numbers in buffer:             10
You must define the following interval:
Interval No. 01
from 0000000001
to 9999999999
internal number assignment
Please look st SAP Note: <b>659573</b>
Hope it helps.
Please award points if it is useful.
Thanks & Regards,

I am running out of memory on my hard drive and need to delete files. How can I see all the files/applications on my hard drive so I can see what is taking up a lot of room?

Either of these should help.
http://grandperspectiv.sourceforge.net/
http://www.whatsizemac.com/
Or search 'disk size' in the App Store.
Be carefull with what you delete & have a backup BEFORE you start, you may also want to reboot to try to free any memory that may have been written to disk.

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Get an external hard drive on which to store some of your files after which you can
      erase the data from your internal drive to free up space.
5. Also see Freeing space on your Mac OS X startup disk.
6. See Where did my Disk Space go?.
7. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.

I have an external hard disk with 120+GB of teaching resources in what may soon become a semi-open access environment. I would like to set up the drive so that a user can view files on it but not copy them onto a CDR or another external drive. Is this possible? I tried setting "permissions", but I could get the effect I was after.
G4 PowerMac Mac OS X (10.4.8)

It isn't possible. If a user has permission to read files on the volume, the user then has permission to copy and save them to another location.
I'd be more worried about your files getting trashed. External drives are very insecure. Even if you try to enforce permissions on them, as soon as the drive is plugged into a Mac, the user will have full read+write access to all its contents by default. That's the nature of external drives.
So I'd start a comprehensive backup regimen to protect the data on the drive, or try a network storage solution on which permissions can really be enforced.

Mac losses connection to the airport hard disk while the pc not !!!

I have an airport extreme (802.11n), Macbook 13" and Powerbook G4 15". And two windows PCs. Every day the mac computers losses the connection to the hard disk that is connected to the airport, and asking for the password, but it fail. While the PCs at the same time having no problems at all. Everyday I have to reboot the airport to use the hard disk. This is strange the Apple product is more compatible with Microsoft windows that OS X !!!!
Note: I have the first airport extreme (802.11n), not the gigabyte.

I am also having this problem. If the PC is not connected, there are no problems sharing files off the drive, but as soon as I connect using Windows, the Macs drop their connection.
The HDD is a 1TB Western Digital My Book. It is connected to the AirPort Extreme via USB.
Thanks!

How can i install windows 7 on my second hard disk while the first hard disk running with windows 8.1

I have Toshiba laptop P-75 model :
this model have two slots for the hard disks , on my first hard disk i am running the default windows 8.1 which came with the original condition (when i bought my laptop) , since i am a civil engineer many of my field programs is not working on the
windows 8.1 version and the rest programs barely works appropriate!
I want to download windows 7 on the second hard disk, thus having dual boot in order to chose which windows i want to use.
thanks in advance

You need to consult with Toshiba as this is a hardware specific problem and you may not be able to install Windows 7 dues to lack of hardware drivers and/or the laptop being configure for Secure Boot which Windows 7 does not cope with either.
It is your responsibility to do the research for this project to ensure compatibility and needed hardware drivers.

Error Code-50 when trying to copy or delete files on external hard drive

Hi,
I am in process of backing up large HD video files from one external hard drive to another using Carbon Copy Cloner software. I get this error message: "This file or folder is sitting on a bad section of hard disk media and is unrecoverable. Delete this item (i.e. in the Finder) and restore it from a known good backup, then try the backup task again."
I have tried to delete that folder in Finder and I get error code-50, it won't delete.
I tried to delete individual files within folder - error code 50.
I tried to "replace" folder with good copy from other external hard drive. Error code-50
I tried to "repair disk" in Disk Utility application and I get error message "cannot unmount disk."
NOTE: the files in this folder are .m2ts format, from an old PC. I converted then into .mov but want to retain originals.
NOTE: I was successfully able to copy the folder from a 3rd external hard drive to the backup disk without a problem (which makes me think it's not the files/folder but has to do with the actual disk.), but cannot fix it on the original (source) disk.
Bad disk?
Bad files?
How do you fix a "bad section of a hard disk"?
Might reformatting the entire disk fix the "bad section"?
Any advice welcomed and appreciated!
Thank you!

Hi
Error -50 paramErr Error in user parameter list
Can there be any external hard disks - if so How is/are it/they formatted ? Must be Mac OS Extended (hfs) if used for Video.
UNIX/DOS/FAT32/Mac OS Exchange - works for most but not for VIDEO.
What this means in Your situation is above me.
• free space on internal boot hard disk? How much ?
Video codec
• streamingDV, AIC etc. (not .avi, .mp4, .m4v, .wmv etc as they are containers not codecs)
Pictures
• in what format ? .jpg, .bmp, .tif, else ?
Audio
• from where/what format ? iTunes, .avi, .mp3, .aiff, else ?
The "com.apple.iMovie.plist" file
Many users has not observed that there are TWO libraries.
• Library - at root level
• Library - in user/account folder - THIS IS THE ONE to look into
from Luke Burns
I fixed the problem.. but it was very, very strange. I had a very long section for credits and set the line spacing to 1.0.. for some reason this caused it. I removed it, and it worked fine. I put it back, and I couldn't preview or play the video.
I don't know why that could cause that big of a problem, but it did..

You need more free space on your hard drive.

After phone support from apple I ended up creating a new project and adding all 117 clips back in individually till I found out what clips flagged and would not allow me to export. I had 3 I deleted and replaced and everything works now 1hr after tedious work....
Where do Your material come from
• Camera
• External hard disk
• USB-memory
And all are connected so that iMovie can find it ?

Restoring my MacBook Pro mountain lion hard disk would affect all my files?

Sounds complexed I know but it's one if those "I'm worried that all my photos, apps, movies, will be deleted permanently!" type of question.
If it does than I can't go back to Facebook where I got my photos from because I permanently deleted that account for anti-drama reasons, as for movies same thing on photos but under iMovie files.
The only option I have is reinstalling my mountain lion.
Please help! I need alternatives!

It would be helpful to have all relavent information.
Your profile indicates that your MBP OS is Leopard. Is your MBP an older one that has been upgraded to Mt. Lion? If so, please provide the exact model and indicate if you have the original install disks.
Is your user data backed up?

Who or what is asking you to reformat the the disk and restore the backup files? What procedures have you been using thus far and what have the results been?

STARTUP DISK FULL NEED TO DELETE FILES IN OTHER

I know vertually nothing about this computer. Am on the road with it and use it for business in my truck. I keep getting a message that says that the startup disk is almost full and it won't allow me to use it until I remove some files. Somehow, was able to bring up storage bar that shows that the "other" which is expressed in yellow, contains the vast majority of my usage or files and what is in there is beyond me. This has all started since I got the iPhone 5 and had to replace it and redownload all in my truck using my verison wifi. Please help you can. Thank you!

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 of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. I've seen no evidence that there is any advantage to having more available space at any given time than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
If you're using Time Machine to back up a portable Mac, some of the available space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.
About local snapshots
Use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
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 see everything, you have to run it as root.
Back up all data now.
Install ODS in the Applications folder as usual.
Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
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.
Paste (command-V) into the Terminal window. 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. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means.
When you're done with ODS, quit it and also quit Terminal.

How do I import an old iphoto library from an external hard disk while keeping my editing and organization in tact?

I am running iPhoto '08 on a MacBook Pro 2.2 GHz Intel C2D (MacBook Pro 3,1). I backed up my hard drive contents onto an external hard drive, then formatted my computer and installed Mountain Lion. I then re-installed iPhoto '08 and ran all the updates. Now, I would like to import my old library from the external disk onto my computer without losing my editing and organization; however, when I select "import to library" from iPhoto, the old iPhoto library is not a selectable option.
I know how to "show package contents" and import directly from the Original and Modified folders, but I don't want to lose my organization. Can I simply drag the content of those folders into my new Original and Modified folders? Will iPhoto read that correctly?
I tried to open the old library from the external disk, thinking to export them all to a folder and import from there, but that just opened my new library and none of the old photos were imported or available.
I'm running out of ideas and would appreciate any help you guys can give. Thanks!!

You don't import it.
Just drag the iphoto Library from the external to the Pictures Folder.
Then open it:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
Never import one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.

Is there a way through aperture to move all of my referenced photos onto a new hard drive while maintaining the current file structure and still keep them as referenced files.

I just want to migrate all of my work (all photos are referenced) from one drive to another and have my aperture library start working off of my new larger hard drive.

Depending on how your folder hierarchy is organized you might be able to do this with file->relocate masters and one of the options of folder organization that is provided but... if you have complicated hierarchy that Aperture will not reproduce then you can just copy all the entire folder hierarchy to the new drive using finder and then use file->locate masters to reconnect them to Aperture like this...

It's actually a bit easier if the old folder hierarchy/drive is disconnected when you do this for a few reasons.
