I Mac Not working, and Repair Disk not working

I have been trying to help out a friend with his I Mac loaded with OS X. It will not load up just by pressing the power button. I have tried running the Disk Utility and get the following messages. I am probably at the understanding of this hard drive is just toast. My next step will probably be to Erease the hard drive completely and try to install the OS X. But i am a little leary about doing that. If anyone could suggest something before I do this, that would be great. All so I have tried booting from the install disk and reinstalling the OS X with out the Formatting of the disk and it does not Allow me to access the Mac HD. There is a big yellow "!"

I cant access any of the files on the hard drive to back up. Do you know of a link on how to format and reinstall. It would be my first time. I have diskwarrior and it will not load at all.
Under the Erease tab I have
MAC OS Extended
MAC OS Extended (Journaled)
MAC OS Extended Case Sensitive
MAC OS Extended Case Sensitive journaled
MS-DOS Fat

External Hard Drive no longer working. Repair disk not working

It appears in the finder, but says I should take everything off of it and restore it.
Weird thing is, it says it's a 465GB capacity, and 236 is available, with 56,708 files on there, but it says 0 items in the finder, so it can't see everything.
I have important stuff backed up on there, but it's not loading.
Disk utility won't repair the disk, and the repair disk permissions are greyed out.
Incorrect number of Access Control Lists
The volume KYLE-HD could not be repaired.
Error: Filesystem verify or repair failed.
Those are what I get when I try to repair disk
Also for owners enabled, it says no, not sure if that is impt. or not.

I'm experiencing a similar issue...
In the middle of copying items from an external drive (ironically, to reformat and enable Time Machine), finder popped up a 'Device Removal' warning... and the two volumes (partitions) of my external HDD disappeared and would not remount. (Disk Utility would not show the drive or volumes.)
I disconnected, powered down the drive and tried reconnecting - same problem... volumes wouldn't mount and Disk Utility showed no disk (despite the hdd showing up under system profiler just fine).
Tried again, and got the problems Kylecool is describing.
Luckily, most of what I wanted to get off the drive had already copied... there's just one more essential (iPhoto library... yes, I have a backup - but I spent a few hours a couple of days ago integrating two libraries into one [a painful process that I don't want to repeat]...).
I'm in the process of copying the library now, and will then reformat - so hopefully no great loss... but thought I'd add my experience to that of Kylecool's as it may be an issue with 10.5?
(HDD is connected via FW400.)

I'm receiving error Boot Device Not Found and Hard disk not exist when I boot up my laptop

I'm receicing the error Boot Device Not Found when i power on my HP G60-235DX laptop. After following HP's recommended troubleshooting steps, I receive error Hard disk not exist. Hmmmm....that's a little concerning. My guess is I need a new hard drive? I have the 17 recovery disks I made when I setup this laptop, however I'm not sure if they will resolve this issue. Any suggestions?

One of 3 things has happened, listed from most likely to least likely
1. Hard drive has died, replace it with one of the same size or larger, then use the HP recovery discs to re-install windows.
2, The motherboard has serious problems. (Replace the notebook)
3. The hard drive cable that connects it to the motherboard has somehow failed, not very likely. (replace the cable)
Replace the hard drive with a new one and use your recovery discs to get Windows back on it.
Here is your service manual, will show you how to replace the hard drive

Using Disk Utility to repair disk not working

Hi, I don't notice any issues with my Mac but I would like to check and repair disk errors anyway. I inserted the install disk that came with my Mac, pressed the C Key while the computer restarted, afterewards I get a menu showing my mouse. What did I do wrong? Any help is greatly appreciated

Without using the correct software shutdown and normally being able
to quit open and running applications, utilities or the System, there is
a chance that repairable issues may result. And in some cases, there
may be a fair chance of damages to the OSX and applications.
Problems with the Directory and other drive/storage files could be
damaged and they may need repairs; if Disk Utility can't do them
then other tools should be used. Disk Warrior can help in some areas
where other utilities cannot do the same job or do it as well. Specialized
tools and some more general ones allow you to restore functions in a
computer's hard drive through various means.
If you do not have a full backup of your computer's hard disk drive, and
then do not have the affordable luxury of wiping the damaged drive,
zeroing it from the booted Installer's Disk Utility options, and then being
able to clone back a complete computer clone from an external hard
disk drive, then you have to see about trying to repair the damage in
the only drive you have. You can be ready ahead of time, to choose one
or another, or both paths. Options are good when you have & control them.
Be sure your third-party disk utilities are compatible with your computer's
OS X version and also with the hardware configuration. Given there are
some computers not running the latest OS X due to non-support, the
utility chosen has to also match with attention to detail, to avoid problems.
Good luck & happy computing!

I just used stellar phoenix mac data recovery and it seemed to work but now my files won't open. Even though they are "jpeg, mov" files the error message is could not be opened. The movie's file format isn't recognized. " Any help or are they corrupted

I just used stellar phoenix mac data recovery and it seemed to work but now my files won't open. Even though they are "jpeg, mov" files, the error message is "could not be opened". The movie's file format isn't recognized. " Any help or are they corrupted?

Sounds to me like the file is probably corrupt. If you had hard drive corruption or damage, that could easily result in recovered files not being fully intact. If you were trying to recover accidentally deleted files, it's possible they might have been partially overwritten before recovering. There are never any guarantees with file recovery.
Without more information on the circumstances that led you to try recovery, it's hard to give advice on what to try from here. You could always try another file recovery tool, like Data Rescue 3. Just be sure you're taking appropriate precautions when doing recovery. See Recovering deleted files.

I recently changed from a pc to a mac book. The major issue I am having right now is getting yahoo to work properly. The major thing is autocomplete does not work and I do not know how to load my contacts to "mail".

I recently changed from a pc to a mac book. The major issue I am having right now is getting yahoo to work properly. The major thing is autocomplete does not work and I do not know how to load my contacts to "mail". Furthermore, I cannot attach any type of documents to my emails (Yahoo says there is a problem). I suspect there is a setting somewhere, but I don't know where. Javascript is enabled, so I am out of options

Which os are you using?
Yahoo issues should be posted in their forums or contact Yahoo tech support.

Help: Just finished shooting a wedding and Aperture crashes constantly during editing. All pic's in RAW and even after making sure I have the latest Aperture update, I have had to rebuild my library twice and "repair" does not seem to fix the issue. Help?

Well!
If you have ThunderBolt, I would go with such for an External Working Drive, spinning platter or SSD depending on your budget
This does not have to be huge just big enough to house your most current Jobs
Once the Current Job is put to rest I would move it to a larger multi bay hard drive unit, USB or FireWire nothing fancy, no RAID, set up as one single Disk
This would only be accessed when something is needed from a past Job so the connection does not have to be speedy
The Drobo would be relegated to Vaults and backups
You can set up a Vault on the Drobo to back up the External Working Library and then Reconnect it when you have moved the Library over to the other Enclosure
This has worked for me pretty smoothly for a long while, but I have found over the years that one can not assume all people work in the same manner! :-)

Time Capsule does not work and i can not not mount it anymore, even after follow all apples instructions at FAQs

My Time Capsule suddenly stopped working, and i can not even mount it anymore. When i ask for a backup, the time machine keeps looking for a disk with no success.
I tried all the FAQs suggestions:
1) I change the name of the disk using Airport Utility;
2) I updated it using Airport Utility.
Now i can not even try to erase the disk because after to update it, the disk in not listed anymore.
Now i can just read a "internal disk needs repair" message. that wasn't there before, having in mind that the first response was "there is no space at the disk for a backup".
What can i do?

The TC has a fault..
Power it down and let it cool off overnight. Power it on again the next morning and check if it works.. no luck factory reset.. do all the tests quickly as you have 10-20min before the Temp rises to kill it again.
No luck it is dead.. give us the actual model number.. A1xxx from the base.
How old is it?? Beyond 3years they do become dodgy.

I am locked out of my iphone. In resetting my passcode I must have hit a wrong digit, because the 4 digits I thought I used Don't work (and of course not my old passcode). I have tried the instructions both for "if you have previously synced your device with iTunes" and "If you have Never synced your device with iTunes" . Neither has worked and I'm in a vicious circle with each time after lengthy downloads it still all ends with the program, & my phone, asking for my passcode to proceed. I'm not sure if I have ever synced to my mac book (i may have) but my address book seems to automatically update on both devices without the need to plug in. Thank you for any knowledgable help that could efficiently get me out of this passcode ****!

Hi DRussell,
If you have not sync'd your device to your Mac then you will have to force the phone into recovery mode and restore as a new device. Read the information in this link and follow the instructions to recover the phone:

After upgrading to OS 10.9.1 Aperature 3.2.3 does not work and I'm not able to download new version of Aperature.

After upgrading to OS 10.9.1 Aperature 3.2.3 does not work and I have not been able to download upgrade of Aperature?

Is Aperture installed in the "Application"s folder and simply named Aperture? If not, move it back to "Applications". Did you buy Aperture from the App Store or as a boxed Retail version?
Relaunch the App Store and sign in with your Apple ID (in the Store menu). Reload the "Purchased" page of the App Store. Do see Aperture on the Purchased tab or perhaps the "Accept" portion of the "Purchased" page? If in the "Accept" portion, accept it to your AppleID and install it. Else look again at the Update page.
For some forum members the update did only appear until after setting the primary system language to English and rebooting the Mac. This bug is supposed to have been fixed with the update to 10.9.1, but try it, if all else should fail.

I have a MacBook Air that was bought April 5, 2011. It seems it should be supported for Airplay mirroring but I can't get it to work and I do not have the icon on my bar. Any suggestions?

Welcome to the Apple community.
AirPlay Mirroring requires a second-generation Apple TV or later, OS X 10.8 or better and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). It also requires the computer to be using wi-fi.

Sorry no backup - no pictures.
Yes phone will automatically backup to icloud when on wifi and phone is charge, but your phone storage was full so it stop backing up.

In my first iPhone 5, the speaker didn't work and people could not hear me on Speaker phone when I used it. When I used the video recording it did not record sound at all only a hissing/static sound, no voice.

In my first iPhone 5, the speaker didn't work and people could not hear me on Speaker phone when I used it. When I used the video recording it did not record sound at all only a hissing/static sound, no voice. I wished for a software fix. I did a hard reset, nothing. I did a full restore to factory settings not putting my backup on and the problem persisted.

I did every step in the link that i have been provided with (thank you), but I’m
still experiencing the same issue. My experience with Apple has been
excellent and this has been the first time I have experienced something
like this with an Apple product. I hope we can find a quick solution.
In order to get the iPhone 5 as soon as it launched (being a major fan of
Apple products!), I purchased my iPhone 5 from the UK through a friend of
mine who lives there.
My question is: can I have the faulty device replaced within Saudi by one
of the official resellers here (we have 3: STC, Mobily and Zain)? I want to
avoid the disruption, complication and expense of sending it back to the
UK.
Could you advise whether this is possible or not, and if not how should I
go about having the device replaced?
Thank you in advance for your cooperation.

Nice try! Take a hike.
