Hard start won't work ?

I have the iphone 4 and the hard start will not work and I receive an error message when trying to restore through itunes on my macbook, any other suggestions?

First, check this: Computers that can be upgraded to use OS X Internet Recovery. If you can use Network Recovery, then do the following:
Install OS X Using Internet Recovery
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.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed 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.
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. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button. Be sure to select the SSD.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

    whats the format on the external HD?
    verify same on another Mac, its likely a dead SATA card inside the external enclosure.
    One assumes you arent referring to a 2012 Air with a Toshiba SSD, since the Air contains no hard drives, only a SSD.
    2013 Air use Sandisk or Samsung SSD.

  • My USB external hard disk won't work anymore after I updated to 10.4.10

    As I said in title since it's quite urgent to me. ALL of my files is in my external hard drive. It's format as FAT or FAT32 I can't remember since I use it between mac and PC. More than that IT IS WORKING FINE UNDER PC. Before updating to Mac 10.4.10 I used my hard disk fine till I updated to this version. I plug in my usb port and after a hours it still won't be detected. I can find my hard disk in finder or desktop. I have tried plug my hard disk to other MacBook or Mac Pro but still won't work anymore. However it's working fine under PC or when I started my MacBKPRO as WindowsXP under bootcamp, my hard disk is working fine, too.
    I have search this forum and seems someone have got the same problem as I face. I don't know what to do...and I feel so disappointed to Mac.

    As Mac OS X has no known viruses in the wild, that leaves you with one of three possibilities.
    1. When connected to the Windows machine, a virus has written over a critical boot block area which allows the drive to become crossplatform. Get the latest Windows virus detection software and make sure the drive is clean of Windows viruses.
    2. The firmware that allows it to communicate driverless has become corrupted on the drive case. Replacing the drive case itself will eliminate that problem, as suggested earlier.
    3. The directory damage is just enough that the boot block itself is damaged. Backup any critical data from the drive onto the Windows machine first, and run Alsoft Disk Warrior 4.0 to repair the directory and see if that works.
    The fact that Mac OS X 10.3.9 won't read it basically eliminates this as a 10.4.10 problem. Only a boot block or firmware issue like this could make a drive not readable on one platform, but readable on another.
    P.S. please note the nomenclature of Mac, versus MAC on this user tip, as it appears you haven't learned it:

  • "C" key CD start won't work............

    I tried starting from a CD several times using the "C" key at restart - but it just won't work!
    Any ideas as to why?
    Thanks

    As far as I know the tech tool CD is not boot compatible with any Intel based Mac including the MacBook Pro. The repair utilities may be, I haven't tried them. As far as I can tell, the information is not officially posted anywhere on Apple's website but my past experience says that it takes weeks to months for the AppleCare discs to be updated.
    This may be official. It says that Tech Tool Pro is not compatible with the MacBook Pro:

  • Copying large files to external hard drive won't work

    I tried looking for this all over google and here, and i could only find old threads that didn't end up with a clear answer, so i decided to post one of my own for the first time.
    Basically, I have folders of music and movies that i'm trying to move over to the external hard drive (2tb WD my book studio using firewire 800) and at one point during the copy, the finder copy window will get stuck and won't move any further. So the copy doesn't go on, and even if i try to cancel it only the beachball starts rolling and finder won't respond until i restart or unplug my external.
    The weird thing is that even when I was copying a few folders that weren't too big, around 2gb or so, it did the same thing. BUT when i took 3 individual avi files that were around 3gb it copied fine.
    I really don't understand what's going on, and I want to just take the entire folder, let it copy, and go do something else rather than sit here moving file after file.
    Does anyone have any idea as to what's happening? I'm not sure whether to blame my imac or my external. external does time machine back ups fine tho.. I have it split into 2 partitions, one for tm and one as a FAT drive. Any help would be great! Thanks!

    All right. So let's say your hard drive is named 'WD MyBook' or something like that.
    Let's also say the folder you're trying to copy is your Documents folder.
    In Terminal, you'd type:
    sudo ditto pathToDocuments pathToWDMyBook
    Now obviously, those are fake paths and don't actually represent where those things are, but that's to illustrate the syntax you need to use.
    Your external drive path will be something like this:
    /Volumes/WD\ MyBook
    The trick here is that if there's a space in the name of the drive, you need to substitute a "\ " for the space. You can also put single quotes around the whole thing like this: '/Volumes/WD MyBook'
    Everything here is case sensitive. You can also drag the icon for the external drive into the Terminal window, and it will paste the path into Terminal for you.
    So the full example would turn out to be:
    sudo ditto /Users/yourusername/Documents /Volumes/WD\ MyBook
    If you wanted to make sure everything went into a specific folder on your external, you'd need to add that to the path you specify. For instance, if you want everything to go into a folder named Backup on your external, the command would then be:
    sudo ditto /Users/yourusername/Documents /Volumes/WD\ MyBook/Backup
    Either way,
    sudo ditto source destination
    That's it, just spaces between everything. Like I said before, you don't need the sudo necessarily, depends what you're copying.
    I don't know if that makes any sense, I'm a little out of it today. Let me know if you need further clarification on any of that, or let me know what you're copying/where it's going and I can probably help you with the syntax. Or just drag and drop! It's easy.

  • My External Hard Drive Won't Work With Final Cut Pro

    Hi everyone! I occasionally use my external HDD for Fianl Cut projects, but only when I'm done editing it. While I'm editing the project, I keep it on my SSD. My external HDD has 3 partitions, one for storage, one formatted for windows storage, and the last one is a Mountain Lion Recovery. When I plug in my external HDD and start FCPX, only the recovery partition shows up.. Any ideas? My pimary hard drive storage with the projects is case sensitive, but the recovery is not.. Thanks!
    Btw, I blurred the video and took out the names to protect privacy. As you can see, my internal SSD and one partition on my external show up, but the "1TB HDD" partition does not.

    I connect my bus-powered HDs (more than one) to the iMac all the time without any problems. I have found, though, that for me the FireWire enclosures work much better (faster and more stable) than the USB2 ones. I have had the USB2 drives freeze my computer once or twice when I connected the HD, but nothing like that has ever happened with the FireWire connections. (I switched the same disk from USB to a FireWire enclosure, so all other elements were kept constant in my experiments.)
    One of my HD is in a MacAlly 2.5" enclosure that offers both FireWire and USB2. The other one is in some generic enclosure with only USB2. Both are bus-powered and both work fine.

  • New Hard Disk won't work

    G4 12" powerbook original hard disk died.
    Replaced with 160GB seagate momentus 5400.3 and it seems to be working ie. disc starts up is recognised by G3 iMac when connected as a firewire drive (start up + T key). Have used disk utility to format it and to mount OS from powerbook DVD but does not work.
    Hardware disc checker says cannot access memory SRR1 & SRR0 with some numbers.
    Is there a driver I need? If so where? or what else can I do?

    Sounds like incompatible memory... but go here and check out the information on how to do a Hardware Test. Might come up with some answers: http://www.thexlab.com/faqs/aht.html

  • WD 1TB External Hard Drive won't work with Snow Leopard

    Hi all,
    I recently purchased a Western Digital 1TB External Hard Drive. It came formatted for Windows with NTFS, but I didn't think this was a problem as the packaging stated it could easily be reformatted for Mac OS. To cut a long story short, it couldn't. When I plugged it in to my Mac (iMac 21" i3) and tried to use Disk Utility to reformat it, partition it, whatever, it just wouldn't work always returning some sort of error. I resorted to using a Gparted Live CD and succesfully formated it to HFS+ but yet when I plugged it into my Mac it wouldn't mount the disk. After following advice to let Disk Utility 'Repair' the disk, this is the output:
    Verify and Repair volume “external”
    Checking non-journaled HFS Plus Volume.
    Checking extents overflow file.

    The volume external was found corrupt and needs to be repaired. [In red]
    Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. [In red]
    If anyone knows what this means, and more importantly anything I can do to try and fix this, I would really really appreciate the help!
    (Obviously I see it says reformat the disk, but this is easier said than done. Now Gparted crashes when it tries to read it and Disk Utility hangs indefinitely if I try to do anything to it)

    I believe the reasons behind this must have something to do with the errors highlighted by the repair process (as copied above)- errors I don't understand.

    If the drive is not seriously damaged ...
    Go to Disk Utility
    Click on the external Drive (not on the existing partition)
    Click on Partition section in Disk Utility
    In the Pane under "Current Scheme" highlite the Partition and then click the "-" (minus) sign down left.
    Click on the dropdown "Current Scheme" and choose a matching scheme

  • My external hard drive won't work on Mavericks

    I have a western digital hard drive that had previously been working flawlessly on Lion, however when using it with Mavericks it had suddenly stopped working meaning it would no longer be found on the desktop or in finder. I have been using the hard drive as a time machine backup. the obvious next step was to launch disk utility and look for a solution. I have found there  two hard drive names in disk utility, the first is the HDD name of Western Digital and the second is the "Time Machine" partition. Running first aid on the partition resulted in an error and that the disk could not be repaired. This HDD is important and the data cannot be lost. is there any solution to bringing the hard drive back online?
    Any response is appreciated

    Is there any free alternative? and here is a screenshot just for reference

  • IPod Nano and my hard drive won't work on my G3....Why!?!

    Hey everyone.
    I'm home from college, and I didn't want to take my iMac with me. Luckily, I have been using an older G3 iBook. It works fine, but when I tried to plug in my iPod Nano, it doesn't recognize it. I didn't bring my Nano install disk. Is there another way to get the computer to recognize the Nano?
    Also, I brought my external Hard Drive home so I have my music collection with me. On my iMac, I have no problem. I plug it in via USB, and it works fine. But again, my G3 iBook doesn't recognize the external hard drive. Now...I'm stuck at home with no music....HELP!

    If you have an older version of OS, then you will be unable to download the newest version of itunes. In that case, the best bet is to restore the ipod.

  • Why my external hard drive won't work now

    Hi guys,
    I have a 500gig USB external harddrive. Today I tried to connect to my macbook mid 2010 and it keeps beeping. When I hear it close to it, it sounds like it start to work for a few seconds and then failed over and over again.
    I have connected it with my harddrive before. Plus I have upgrade my system to 10.8 golden master and upgraded my memory from 2 gig(2*1gig) to 5gig(1*1gig and 1*4gig) I don't think that's the reason. I've been using my mac with the power adapter all the time. Tried reset my SMC.
    Thanks!

    I do not know what a sdd is, but certainly it is a normal Harddisk.
    If you have TM on it, open TM preferences and reallocate this disk under "select disk" to TM, check under "options" that this disk is on the exclusions list. And in Disk Utility check how much free space you have on this disk (500GB is quickly filled with TM, and not always it condenses correctly).

    The drive currently has two partitions on it, one for my iMac time machine and one for my MacBook Pro time machine. When I try to repartition this drive in Disk Utility I get the error message:
    "Partition failed with the error:
    Could not modify partition map because filesystem verification failed"
    I need to clear some storage space on my internal MacBook drive and I really don't want to spend money on another external disk when I have over 500 GB just sitting there empty. I would just write directly to the current partitions but OSX flips out when you try to save random files straight to a Time Machine formatted disk.

    This seems to be a common question and problem around these parts. I am certain one of the resident geniuses will soon be responding.
    While we both wait for that to happen, you may find some helpful information by doing a search for "repartition hard drive" or "repartition time machine" in that little search box just to the right. There seems to be lots of good information there.
    But remember that monkeying around with partitioning is not without risk, and we are talking about your Time Machine backups here.
    Be careful and good luck.

  • Formatted External Hard drive won't work

    I formatted my external hard drive using the MS-DOS(FAT) in Disk Utilities so I could use it on my windows and on my mac. After the formatting finished, I copied some folders to my hard drive from my macbook and ejected it, then plugged it to my windows laptop and I get an alert "You need to format the disk to be able to use it" or something like that. Of course I don't want to format it because I don't want to lose the files since I already deleted them from my macbook. So I plugged my hard drive again to the macbook and i can't find it. I went to Disk Utilities and tried repairing but it couldn't repair. Now my external hard drive is not readable on both and I don't want to format before I can at least copy my files.
    What to do?!

    If you can see it on the computer not much.
    There are disk recovery services that can retrieve data from such disks but their service cost $$$$
    How much is the data worth to you?
