Will repair disk utility delete all files on harddrive?

I have a "Mac OS X Install Disc 1 2008 Apple Inc." disk. Will this get me to the Disk Utility?
Will my harddrive be, mostly, unchanged or will it delete all?
Any other advice would be appreciated!
Thanks in advance,

Mostly unchanged. Back up the data anyway.
Since you're running Lion, restart with the Option key held down, tab to its recovery partition, and use the Disk Utility from there.

What will happen if I delete all files .plist? specially from Web?

Could the app iWeb or in general the iMac get faster? iWeb is crashing and doing funny things all time today...
Thnaks,
Raúl

The first steps in troubleshooting iWeb are to quit the application, go to Home Folder/Library/Preferences and delete the file com.apple.iWeb.plist and relaunch.
If that doesn't do it, delete the .plist again, restart your Mac and run Disk Utility to repair permissions.

1 more time: I installed Samsung 840EVO SSD and tried to clone the OEM drive to it. Disk Utility shows all files landed in the new SSD thru the USB to SATA converter cable yet my Mac won't boot. Why's that?

The question is why won't my Mac boot with the new 840EVO SSD that I thought I'd successfully cloned all contents from the OEM hard drive by using a USB to SATA converter cable. Disk Utility seemed to indicate the SSD had captured everything from the OEM drive. Note the OEM had 2 partitions to run Parallels Windows XP

XP is not supported externally or if you install Mavericks, and Microsoft is trying their hardest t o get people off that old tin can, rightly so.
Usually Carbon Copy Cloner will. Usally. DU is not really meant to and you had 4 partitions before.
This forum is not for MacBook Pro btw.
Cloning with DU or CCC may do a perfect job but not be bootable if t he interface or case is not.
The EVO is capable of 500MB/sec so even your mid-2010 MBP is not going to get the top performance but should be better once you swap it out than what you were using.

HT4847 On startup my macbookair says start up disk full/delete some files. When I look at storage disk utility I see 51GB of a possible 60GB is used with Other. What is Other? and how can I view and delete some of these files?

A MacBook will use Time Machine to make local backups so that when connected to an external drive it will backup a lot faster.
to disable this, you must use a command under terminal.
to locate terminal, do a search for it under spotlight (the magnifying glass on the top right corner), should be the first hit.
once under terminal, type the following text exactly:
sudo tmutil disablelocal
hit enter.
you will be asked to input your password, if you do not have a password, you will have to create one before performing this command. after entering your password, hit enter again and close terminal.
in a few minutes the space taken up by time machine should be cleared.

Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Will updating my ipad delete all the files and apps i have there?

Will updating my ipad delete all the files and apps i have there?

Perform a complete backup before hand and all will be well. You just restore the backup after the update. If you have a backup password, be sure you haven't forgotten it. The details of what is backed up differ a bit if you are outside of the states. Read this article for details:

Will restoring my MacBook delete all of my software?

I currently have OS X Lion and I want to downgrade to Snow Leopard since it is more compatable with most software. I have to restore my computer in order to do this. Will restoring my computer delete all of my software on my computer? Will I have to install everything once again?

Downgrading will require that you erase the drive, so everything on the drive will be deleted. You should make a backup of your system beforehand, although not everything can be restored that may be Lion dependent. Here's the downgrade procedure:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, 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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Can I delete all files and users (including admin account) without re-installing SL?

I have a 1st generation Macbook Air, running Snow Leopard 10.6.8. Just bought myself a new MBA, want to sell the old one (privately, not soliciting here).
The original install disks were Leopard. I bought a family pack SL and upgraded the MBA at that point. Earlier this year I sold my old Mac Mini (when I upgraded) and included the SL install disks with that sale (stupid of me).
Now I want to sell the old MBA. Ideally, I'd have a clean install on SL on it, minus all previous files and accounts. I've done that before when selling old computers, reformatted / erased the HD, then reinstalled the OS. But I don't have the SL disk anymore, and I don't really want to pay for it just to prep this notebook for sale.
AFAICT, my options are:
wipe the HD and reinstall Leopard (the only OSX disks I have). Whoever buys it from me would need to upgrade to SL themselves, and from there to Lion if they want.
somehow try to delete all files and users without touching the current install of SL. I'm not terribly worried about security of what little information is on the MBA (nothing important to me), so I don't mind trashing files and then emptying trash instead of wiping the HD block by block.
Any ideas for how to do #2? I can trash all files/folders under /user, uninstall all applications and delete their folders from Library, uninstall all browsers except Safari and wipe the history from that...
Is there other stuff I should be deleting? plist files, maybe? I'm leery of messing around too much and disrupting the install of the underlying OS.
Can I also delete the admin account (or rename it "admin" with a generic default password?)?
Any other suggestions? Thanks.

Trashing files you have created is relatively easy. Getting rid of an account is a bit harder. Trashing the .plist files, etc., that may contain personal info is a lot harder, and there is always the risk that you will miss something.
Best, and easiest, and customary, is to do option #1 - wipe the drive and re-install the original OS from the original disk set. The receiver of the machine can then decide which OS they want to upgrade it to, and purchse accordingly.
The original disk set for that machine should be included with it when it is sold.

I do not recommend reformatting your harddrive and reloading your software. This is a Windows thing. On an older mac it may be difficult to find all your software again.
Best to have greater than 2gig of free space. Many posters to these forums state that you need much more free space: 5 gig to 10 gig or 10 percent of you hd size.

Be careful when deleting files. A lot of people have trashed their system when deleting things. Place things in trash. Reboot & run your applications. Empty trash.
Go after large files that you have created & know what they are. Do not delete small files that are in a folder you do not know what the folder is for. Anything that is less than a megabyte is a small file these days.

How much space is your Other using? You may be able to reduce.
How Do I Get Rid Of The “Other” Data Stored On My iPad Or iPhone?
http://tinyurl.com/85w6xwn
With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

Deleting all files prior to sale of my iMac

I am selling my 2009 iMac abd want to9 delete all files prior to giving to the new owner. I have tried DiskUtility but the formet etc and security buttons are greyed out. Please help.

Throw away any files which may contain sensitive information, securely empty the Trash, and then run the Disk Utility when booted to a Mac OS X install DVD(if it originally shipped with 10.6.8 or earlier) or the computer's recovery partition.

Please help
Greetings from Vienna

If you open Macintosh HD > Applications > Utiltiies > AirPort Utility and click Manual Setup, are you able to access the settings for the Time Capsule?
Or, does AirPort Utility scan for the Time Capsule and then not find it?

HT1923 This article contains the only thing that worked for me. I also had to sign out of iCloud and uninstall it. Then I had to delete all files and folders from all of those applications that were under Program Files, Program Files x86, and Users.

This article contains the only thing that worked for me. I also had to sign out of iCloud and uninstall it. Then I had to delete all files and folders from all of those applications that were under Program Files, Program Files x86, Program Data and Users. My iPhone 4 will now sync with iTunes both in its USB-connected mini dock and over Wi-Fi. It's unfortunate (negligent programming on the part of Apple?) that the upgrade to iTunes 11 did not remove all of those files as part of the upgrade process.

I am having the same issue....Same address for years - same as USPS - I tried 5 times (3 macs and 2 iPhones) and now i have 5 CHARGES for 1.00 each on my credit card. I took the credit card info off so they don't charge me anymore. How can they charge me yet still not allow me to download free updates and say I have an invalid address? I'm sure I will spend weeks or months trying to get a credit out of these incompetent idiots.
