Utility drive on iMac saying HD is corrupted

Disk utility saying HD on iMac corrupt, what can I do about it?

  1. If you can, tell us exactly what the error message is that you have found.
  2. There are two possibilities - there is a problem with the player software, which may or may not be repairable, or that the disk is a failure (hardware problem).
  3. Have you ever used any "cleaner" type applications, such as MacKeeper or CleanMyMac? or anything of that kind?
  4. Before you try this, you should have a good (if possible) backup of your hard drive with Time Machine, for example.
  5. If you haven't done so already, start in your recovery partition (restart and press ⌘ + R until you see the apple logo) and then fix your hard drive with disk utility. Disk utility (El Capitan): a repair disc
  6. If #5 does not work, then I save your documents (if possible) and then use the recovery partition again to wipe your hard drive and reinstall OS X from scratch.
  7. If #6 does not work, then you can try to boot from the recovery of the internet (⌘-R option to reboot) and the apple servers allows you to reinstall the OS X. OS X: on OS X Recovery - Apple Support
  8. If this does not work, I would like to replace your hard drive. They all fail eventually after a few years. Yours lasted longer than most.

  • Migrating to SATA drive to iMac

    Four days ago my MacPro (2010) died. I have four 3 "SATA drives from 1 to 2 to each of Mac Pro. The computer was for business and personal use. Absolutely everything (including financial information) I have is on these four discs, including redundant copies of some files, but also my Time Machine backup.

    I will have an envelope coming tomorrow which is a RAID box but will be executed in the independent drive with four drives Mode. My 'new' computer is an iMac (2013), that was given to me.  The iMac and the main SATA drive running the same version of the operating system. I need to resolve this issue quickly so I can return to work. In the immediate future, I intend to operate out of the primary SATA drive to catch up, and then transfer when I'll have a good time to transfer.

    My question is the best way to get the entire contents of the primary SATA drive on the iMac's hard drive. I want everything that is on the main SATA drive to put to be on the iMac (including the prefs and hidden folders) of Mac Pro and it would be the same when I booted the Mac Pro.

    Can I use migration utility, clone the drive SATA main to the iMac or even use the Time Machine backup?

    If I clone the drive, I know that I would have to boot from one disk other than the iMac drive to clone to the iMac. When the primary SATA drive is attached, I need to boot from it by holding down the option key at startup key to select the startup disk.

    If I use the Migration utility, it seems I start the iMac, and then run the utility to the iMac of the SATA drive range, which would be connected to the iMac. This would replace all the information on the iMac even though it was the boot drive?

    I printed the information on the Migration of Apple Mac help when transferring to another storage device, but it's not quite clear to me.

  • Implement the external dvd drive on iMac

    Hello

    My superdrive drive started acting funny (not eject disks and then do not read), so I bought an external dvd reader/player.
    Everything worked fine until I installed an SSD instead the superdrive.
    Now, when I go to play a DVD in the DVD drive external drive says "there was an error of initialization, a valid dvd drive could not be found."

    Other applications do not recognize the dvd either, as they did.

    Disk utility will find the dvd if it is in drive but you will not find the player if there is no DVD.

    Is there something I can do to recognize the DVD player as the default player for the iMac?

    Thank you

    iMac 24 inch early 2009

    El Capitan updated

    DVD writer Samsung laptop, SE208

    There is nothing to recognize without a disc in the DVD player. It's normal. Apple's DVD player software does not work on my iMac 2009 with the original drive in an external case because I also installed an SSD in the optical Bay. I use VLC to watch videos. My disc burning software, Toast, recognizes external very well.

    I also bought the 10.3 disk 3 cd OSX Install discs.

    When I put disc 1 in hold C and start the IMAC I get a gray screen with a gray circle with a line through it.

    Maybe I was reading that this is caused by installing is not the correct OSX?  I looked on everymac.com and found that it was originally shipped with os x 10.3.5

    do I need to get a drive to 10.3.5?  He will tell 10.3.5 the disk?  my 10.3 that I bought new in the box never open just says 10.3.

    There are hundreds available that will work. I went with an OWC SSD and used their installation kit on my 27 "2011. The SSD is behind the SuperDrive which allows me to keep the internal storage HD and SSD. OWC has great instructions online, a toolkit including the right cable and the best support.

    There is a difference between "code" and "corrupted". What is the exact text of the error message? You actively encrypt these files? Either way, a USB flash drive is not a good permanent backup solution. Suggestions for the backup here:
