  • Mac Data Recovery after Re-installation

    Re-installation is the process of installing the operating system of your PC once again. This means that the entire hard drive is formatted, re-partitioned and a new copy of the operating system is installed in your computer.

    When you need to re-install Mac OS X?

    • If the PC is severely infected by viruses then re-installation is done as a recovery method, so that it may eliminate these unwanted viruses that are cluttering your Mac machine and slowing its performance
    • Hard drive crashes are so common and can occur at any point of time. In such cases re-installation becomes necessary
    • If Mac OS files get corrupt due to some unknown error then you need to re-install Mac OS X
    • If you are upgrading the Mac OS X to a new version for more improved features
    • Sometimes Mac OS updates may cause error and makes the system unbootable, here re-installation is to be done to bring your Macintosh to normal functioning
    • To increase system performance and speed that have lost over the time due to various software issues and other system errors

    How data loss occurs due to Mac Os re-installation?

    Even though Mac OS re-installation is a simple procedure and recovers you from many problems, but this may also lead you to a data loss situation where you may lose all your personal files, music, photos, videos, documents etc.

    When re-installation is done, it offers two ways to re-install that is "Archive and Install" and "Erase and Install". So in case, if you accidentally select “Erase and Install” option, then you will end up losing all your files and folders. Even if you select “Archive and Install” option (i.e. takes backup of your volumes using Time Machine) and installation fails in between due to some error, then also you will lose all your data due to inaccessibility of volumes. Hence, it’s very important to take backup of your files to an external storage drive before re-installation.

    What to do if you lose data after Mac OS X re-installation?

    As pointed out above, a small mistake or error can cost you a severe loss. Therefore without back up of your important and critical data then this can be tragic. But don’t be concerned, as we provide you with the best way to recover them back. Use Yodot Mac Data Recovery Software, which can help you recover and regain all your lost data after Mac OS re-installation, that too within no time.

    How to use the software to recover data after re-installation?

    • Firstly, disconnect the affected hard drive and attach it to a healthy Mac computer as a secondary drive
    • Download and install Yodot Mac Data Recovery software to that healthy computer
    • Choose “Volumes Recovery” option from the main window, in order to recover all the lost data from Mac volumes
    • The application will display the physical disks that are present, select the slave drive from which data is to be recovered
    • As you proceed further, the next window displays all the volumes / partitions that were present in the selected hard drive before re-installation
    • Choose the one that holds your important files
    • From the next window, you may select the desired file type, which you need to recover or select “Mark All” option
    • Select the files with the help of distinct view types, so that unwanted files can be avoided and disk space can be saved
    • Preview the recovered files for satisfaction regarding recovery and selection
    • Store the recovered files to desired location or drive, you may also compress them before saving (this option is disabled in trial edition)
    • Since, the option is disabled in trial edition, you may use “Save Recovery session” option for saving the scan session and later after product purchase, you may use “Open Recovery Session” option to continue from the saving step
