How do i repair a corrupt hard drive and i lost my install disk

My Macbook started acting up....when rebooting there was a flashing file folder with a ? inside. Finally got to reboot, ran Disk Verfiy and my hard drive is corrupt. We just moved and I have no install disc. How do I repair my hard drive?

With no install drive and a potentially flaky boot drive there is no guarantee of success.  Here's some schemes you can try.
1. Boot in safe mode.  I believe it does a fsck (file system check) of the boot drive.
2. Related to 1.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
3. Ggt yourself an external drive and hope you can clone the boot drive to it using Carbon Copy Cloner (or Super Duper).  Then boot from the external and try to repair the original boot drive.
Of course I shouldn't have to say that you should always have a backup (backups) of your drives anyhow.
4. Contact apple to try to replace your installer dvds.

  • New Hard drive and no original OS install disks to hand.

    Hi,
    Just installed a new WD hard drive after my original HD died after 2 and a half years of use, unfortunately I do not have my Tiger disks to hand. Do I have to buy the full Snow Leopard Box Set to install with no previous OS system or could the SL upgrade work? I am not really interested in iWork etc. Thank you.

    you need to buy the box set. another option is to buy leopard and a snow leopard upgrade disk. also, you can call apple and request a replacement Tiger disk. they will provide one for a nominal fee.

  • How can I wipe hard drive and do a clean install of Mavericks?

    I have a 2012 MacBook Pro that is terrible sluggish, probably from upgrades and semi-deleted Symantec software. I want to wipe the hard drive and do a clean install of Mavericks. I have all files backed up, and can reinstall software.
    I think there is a way to do this with Disc Utility?  But don't know how.  Advice welcome

    If you have Yosemite installed and want to reinstall it, do a backup,  preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors.  Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Then re-install the OS.

    When you reboot, use Setup Assistant to restore your data.

  • I have Lion on an external hard-drive and I want to install it on the internal disk

    I have Lion on an external hard-drive and I want to install it on the internal disk. How can I proceed?

    I recently completed a clean install of Lion on an internal SSD. After wiping it clean, I used a thumb drive with SL on it to boot and then another thumb drive with Lion on it. It worked just fine. The only thing to be aware of is that if you use the thumb to install Lion from... it will not install a recovery partition and you'll have to use the thumb in the future.
    That's what I wanted anyway so it's working out just fine. Good luck.
    I should add... I used the SL thumb to actually boot from and used Disk Utlities to wipe the internal SSD. It does work and there are Apple posts that can guide you through the thumb drive process. I used copycat to create both the SL boot and Lion.

    Exactly which hard drive is it? Give us the specific model so we can look it up.

    If you have restored the hard disk to its original out-of-the-box contents using Toshiba recovery media, that probably means you restored to a drive with the new advanced-format technology.

    Be sure to start your iMac using its original grey System Install DVD: Insert that disc and start your Mac while holding the d key. At the Mac OS X Utilities screen select Disk Utility and format the hard disk. Select "Mac OS X Extended (Journaled)".
    Then, install OS X.

  • How to use time capsule as hard drive and connect with existing net gear router

    I have a netgear D6300 router, which i use to connect to internet - which is excellent so far for my downloads and games etc for my PS4 and hence am keen to continue using it. I bought the Airport time capsule for wireless storage, and when i set it up, I was advised on setup to connect the TC to my router, and it did what it needed to do.
    Now, in order to connect to internet, i need to connect wifi to net gear router, but to access time capsule, i need to change wifi connection to my newly created wifi network with TC.
    I want to use TC as a backup storage for my mac (its a 3TB TC), but also, my laptop has only 500gb hard drive which is now half full from downloads, so i want to transfer all my downloads to my TC and use it as an external hard drive, and future downloads to TC - but when i connect to wifi of TC, i can copy my folder on my mac, but not paste it to TC in finder. (the only thing in TC is an image of tmg of my macbook from first backup.).
    How do i use TC as an external HD - there wasn't much difference in price of external wifi/wireless HD between non-TC and TC at 3gb, so i just thought i'd go for the airport TC option.
    And is it possible to keep connected to wifi internet via net gear router, AND wifi TC - the whole point i bought it (from US shipped to australia on eBay, therefore not able to send back) was to use TC as external large HD via wifi, but keep my net gear router going.
    Surely there is a way to not having to flick between wifi connections of TC and net gear internet.
    When i'm connected to TC, i can't access internet, only TC.
    And I don't really want to connect TC to my router via ethernet cable, as too many cables.
    This can't be a difficult situation to manage, but i'm not sure how to do it.
    Thanks

    And I don't really want to connect TC to my router via ethernet cable, as too many cables.
    Sorry but you have very little choice.
    The TC can join to a wireless network.. but it is flakey, poor, slow and highly NOT recommended way to do things.
    Nevertheless if you want to give it a try .. here is the method.
    How do I setup my time capsule with wireless internet?
    You SHOULD, plug the TC into the Netgear and run it in bridge mode.. you set the wireless to create a wireless network.. then when you connect to the TC it will be also connected to the internet and fast.
    (if you don't do that you may as well have used a USB drive plugged into the Netgear, as it would be just as good).
    TC is not actually designed for mixing Time Machine backups and files.. but if you are just storing downloads that is ok.. but I strongly recommend you use a DMG or sparsebundle to prevent the TM and the data from messing each other.

  • How do I replace my internal hard drive and not lose windows partition?

    Hello,
    I am wanting to swap my internal hard drive out for a larger one. What do I do about my windows partition? I only use boot camp, and there is some stuff on my windows side I don't want to lose. I know how to make a clone for OSX, and I know how to replace the actual hard drive, it's just the windows that I am a little sketchy on.
    Thanks for your help.

    WinClone - check the faq and forum for tips and read the docs
    http://www.twocanoes.com
    Pull your hard drive and put it in external case, OWC sells such kits, you could probably use a good windows clone program too.
    but you need room on an (external) hard drive to hold the Windows image (uses a sparse disk image file is all).
    Paragon Software has been busy releasing programs and updates to help Mac users running Windows, using NTFS (and EXT2/3), as well as CampTune (free for now) for resizing Windows or linux boot camp partitions.

  • How can I securely erase my hard drive and reinstall OS X Mountain Lion?

    Hi, I am selling my MacBook and I was wondering if there's a way I can securely erase my hard drive, (... 7 pass, 35 pass) using these steps: http://www.mactip.net/how-to-securely-wipe-your-mac-hard-drive-before-selling-it /
    and also reinstall OS X Mountain Lion afterwards.
    Thanks in advance. 

    Boot into recovery mode by holding the command and r keys down during boot. Bring up Disk Utility and do the security erase you want to do. When done, choose to download Mountain Lion.

  • How do I encrypt my external hard drive and subsequently a specific file within it, using my Mac? I tried creating a disk image but permission was denied.

    Encrypting an external hard drive and specific folders within. Permission denied using disk image.

    VKP90 wrote:
    When I tried to encrypt a single file within the hard drive itself, I got the following: Disk Utility Progress: Unable to create "Name of my file" (Permission Denied).
    When I tried encrypting the entire hard disk itself, I got: A GUID Partition Table (GPT) partitioning scheme is required.
    I have also currently used Time Machine on the external hard drive, along with saving other data. Hence, I am not sure if partitioning is going to delete any of this (a video I watched mentioned that using the + button when creating partitions retains current data). Backing up the external hard drive is out of the option since it is the back up to my Mac.
    You can't encrypt a single file. I'm not sure what you did to try. You can make an encrypted disk image which begins with a folder, if desired. Or, you can just create a blank, encrypted disk image, then move your desired files into that.
    While you could partition off the free space without erasing the disk, you cannot encrypt it because you need a GUID Partition table which requires you to repartition the entire drive, not just the free space.

  • IMac 17" Hard Drive and DVD dead after install.

    I am attempting to install a WD 250gig hard drive into a 17” flat panel 800mhz imac. I followed the directions of taking the base apart and installing the new drive with great care. The Original 80 gig drive was set to master and the DVD drive was set to slave. I set the new WD drive to master and put the base back together. All I got was a flashing question mark. That was not unexpected, but I have been unable to get the iMac to recognize the existence of a hard drive or the DVD superdrive. I started the iMac from my Powerbook in firewire target mode. And verified that the iMac does not see the drives within the system information or the Disk Utility.
    I have tried resetting PRAM, changing the jumpers on both drives, making the DVD master and the HD slave, setting the HD on cable select. Formatting the HD in my Powermac and cloning the original HD to it with CCC and replaced the ribbon cable. I now can take this iMac apart and put it back together faster then a Chinese factory worker.
    I have abandon hopes of a new hard drive and put the 80 gig back in exactly as I found it. The iMac will not recognize the original configuration either. I started this project as favor for my sister who owns the iMac. There is not a lot of money here to send the whole works into service.
    Does anyone have any ideas on what went wrong?
    Is there a way I can test the power supply to the drives?
    imac 17" FP 800 mhz   Mac OS X (10.4.7)  

    Well we figured it out. DO NOT TRY THIS AT HOME. Since nothing we did worked, I figured we had nothing to lose. With the assistance of my electronics wiz brother, we powered up the iMac while having the base opened and the components spread out on a table. Using a voltmeter, we determined we were only getting 3.6 volts to the drives. It should have been 12 volts. Somehow, something went wrong with the system board. After careful examination under a magnifying glass and some prodding with a voltmeter, we discovered that a tiny component next to the power connector on the system board fell off. It was no more than 2mm across and was marked (L13). We figured this was an inductance component and probably a filtering device for the power to the drives. We powered up the board and jumped the leads with a screwdriver. The HD and DVD fired right up. A careful soldering across L13 made the fix permanent. I got it all put back together and everything is running great.
    The moral of the story; be extremely careful when pulling connectors off the system board. I must have knocked the component off when I first took the iMac apart. I just got lucky we found out what it was and were able to find a quick fix.
    This a nice little iMac, but i never want to work on one again.
