How can I repair a HD without start up cd?

I have problems with my MacBook Pro I upgrade to Lion and it works fine but som HD problems start happen, and it looks that I need to repair my HD, but I don`t have a start up CD, I only have the Mac OS X; Should I have use that?

Repair the Hard Drive and Permissions - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
To boot from the Recovery HD restart the computer. After the chime hold down the COMMAND and "R" keys until the spinning gear appears.

I have iphone 5. I deleted my iCloud account because I started a new apple id with a new email address. I can no longer log into apple id with my new email and pw. How can I get it on without starting all over?

I changed my apple id on my iphone and macbook but now I cannot get my iphone to accept it when I go into icloud after deleting an OLD apple id.

It is not possible to do that.

Will I lose my emails I have on there? I have numerous client email files and can't afford to lose any of them. I do have everything backed up but I'm fearful of losing important client info. What if something happened during the back up and it doesn't have my files?

When you erased the disk did you select Mac OS Extended Journaled as the format option?

Only way to get iMac starting again was to re-install 10.4.4 from DVD, and then update it into 10.4.6. For a while it worked perfectly, just as before.
Then I tried to print to CD with my EPSON Stylus Photo 950 from Adobe Photoshop Elements (2.0). It didn't print anything, but printer started flashing all lights. The print job was not performed, so I did remove it from the Printer Utility. After that the iMac started "ticking" again, same noise than before, after 10.4.7 installation. I did re-boot iMac. It never started, it does stuck on gray screen (gray block running clockwise). HW test from DVD didn't find any problems (extended search looping 3 times). But Disk Utility found hard drive to have inaccurate node structure, it could not fix it.
Apple support recommended to use DiskWarrior. However, it does not support (yet) Intel Macs. I haven't got TechTool Pro 4.5.1 anywhere. iMac does start on to FireWire mode (T at boot), but I cannot see the disk from 10.2.8 iMac.
So, obvisously the problem is not 10.4.7. I believe it to be ESPON printer driver compatibility on Mac OSX. This does not suprise me, EPSON printers *****, I shall never purchase one again. However, disk catalog structure should not get messed by one faulty printer driver!

i cant get started my ipod nano 5th generation,is dead ,how can i repaire it

As I said in my previous reply:
You either have to enter the ID and password of the previous owner or get them to remove the device from their account

I would return the iPod for a refund. If you can't then turn it into the police since it is worthless to you

HT1918 how can i setup my account without a credit card

how can i setup my account without a credit card

Thanks SniperKat but I don't know why for some reason the "NONE" disappeared...
I started to create an account and when I saw the credit card thing I just clicked back and back and so I closed the browser... every free app or something free I get it appears a window : " You have to review some of your information about your account" .... but I don't have an account yet because I didn't create it.... the only solution is to create a new e-mail account and go to iTunes store and create a new account with the new e-mail and be very carefull with the "Free app" this time...

Where is the backup of the media and other important files from the computer? Ultimately, it is the users responsibility to ensure that backups exists. Waiting until there is a problem to decide to do a backup is not smart. Would you wait until a fire started in your home to call the insurance company and inquire about homeowners/renters insurance????
In the event that no backup exists (stop being lazy.... keep backups of YOUR data and other important files):
If you are in the US and running iTunes 10.3 or later, it is possible to redownload music via iCloud from purchased history.
If you are not in the US or for some reason cannot run iTunes 10.3 or later, contact iTunes customer support and ask very nicely for the opportunity to redownload the content. They are not required to provide this opportunity.
It is also possible to transfer content from an iDevice that was purchased via iTunes. On the new computer, sign into the iTunes account, authorize the computer, connect the device then select File > Transfer Purchases.
The simplest method of all is to transfer or copy the media (and other important files) from the old computer or the backup of the old computer. Typing "move itunes library" into the search bar here or into google will reveal step by step instructions on how to do this.

How can you listen to music without headphones?

How can you listen to music without headphones?

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
Try the following to rule out a software problem
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.
Apple Retail Store - Genius Bar
Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.
Apple - iPod Repair price
A third-party place like the following will replace the jack for less. Google for more.

HT1420 I just bought my cousin's ipod, and I want to update it on my computer. However, it needs authorization from his account to keep all the apps, and he's already authorized it on 5 computers. How can I update this ipod without losing all the apps?

You cannot use someone else's apps without violating the license agreement. The apps are tied to the owner (via Apple ID). The right thing to do would be to update and start fresh.

How can you delete an app without losing saved data/progress?

How can you delete an app without losing saved data/progress? Is there a way through iCloud? I have an 8gb 4th gen iPod touch. I have a lot of music, so with 8gb, space is limited. Some apps I have take up 20-30 MB. Some of these games I don't play that much, but I don't delete them because I have made a lot of progress (levels, scores, acheivements). It would be nice to delete some of these 30 MB apps that take up precious space, and them redownload them in the future when I have more space, but without having to start the whole game over.
Also, I read somewhere that there might be a way to do this with iCloud, but I don't really know how.
Thanks!

This is the only way I know of. It is messy though.

How can I recover a book I started from a file?

I have recently installed the iPhoto 9.2.1 from App Store.
I am having many problems with iPhoto after an electrical cut when I was working with it.
First, when I opened iPhoto immediately after that, many of the events appeared in black box, when I open a file of these, black boxes appears, photos could not being seeing, but click in one, the photo appears.
I realized that those files I did not working with them for long.
I am interested to recover them, How could I do it?
I copy iPhoto Library into a external hard disc to safe and start from the beginning. I need to work in one book.
Second,The photos for that book were in the external hard disc. I imported them into iPhoto and start working. I thought that everything was solved out.
This morning when I opened the computer and iPhoto, My work, begun the previous day, was not there, iPhoto ask me if I want to recover iPhoto Library and thinking that that was my last work, I said yes.
But it was not, It was the old library, but the work that interests me has disappeared.
How can I recover this work I started? It must be in some place.
Thanks for your advice

Sorry, it'll be impossible for any of us (the forum regulars) to post in this thread without making obvious suggestions like this; it's safe to ignore these suggestions, I understand that you are powerless here to make reasonable suggestions like "Fire the incompetent translation firm that can't keep up with its clients and retain one that actually has the licenses for the apps necessary to complete the project." If nothing else, all of the people who search Google for the phrase "translation downsave CS5 CS4 book" will learn that the best answer is "tell your translation supplier that they will lose your business if they fail to upgrade."
But in your case - no, I know of no such script to re-save a CS4 book from IDMLs spat out of CS5. The scripting forum is thataway; maybe they know of a script someone else has already written for this purpose. Mostly because, especically in a book file, one of the steps before saving the INDDs and book in CS4 should be "a human compares the IDML opened in CS4 against the INDDs in CS5, or PDFs generated from same, before Saving As CS4 INDD."

That issue can be caused by an extension that isn't working properly.
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
