    Re: Steps to follow to securely erase the hard disk data in Mac?

    There is a option given in your Mac to make sure that the datas getting erased and you can very well erase all the data in your Mac from the hard disk and then sell it for better price, you are really taking a good step that you are making sure that you are erasing the data securely as most of them just format it to get rid of the data. So now to erase the data securely in your Mac just make sure you following the steps given below,

    STEP 1: Get your Mac installer CD which came along with your Mac and insert it while booting your system and press C key when the system starts up.
    STEP 2: In the installer -> Choose Disk Utility from the menu bar.
    STEP 3: Now select the hard disk which you want to erase and select the Erase tab.
    STEP 4: In that choose the Security Options button -> There will be four levels of security to choose from there and each higher level will take more time to erase.
    STEP 5: So select the level which you want accordingly and select the option Erase.

    If you are not erasing the main system partition then you can do the same without the installer CD but going to the Utilities folder and opening the Disk Utility from there. So take your pick and erase the data in hard disk from your Mac accordingly.

    Still you are not able to follow the above steps or if you are facing some other issues while erasing the data in Mac, just drop in your query in order for us to get back to you with the best solution.

    Dear...

    Every OS and every hard drive have an option to erase or delete hard disk data.
    Try to find in hard disk option to erase the data.

    If you could not found, then format all the drive because you wan't to sold your Mac and the data consist in your Mac Book is no longer use for you.
    So why you are thinking so much.
    Just format all the drive except the OS one.
    If you can't get this option, then follow your user manual.

    Thanks Dear...

    HELLO SIR........

    you are selling a hard drive and need to delete your data from the drive or simply need a completely clean and formatted hard drive to work with, securely erasing the drive is simple, using some freeware utilities or even some default utilities built-in to Windows or Mac.
    plz Watch this Video : -

    Re: Steps to follow to securely erase the hard disk data in Mac?

    Before erasing your data , you must take backup. You can erase data by using Disk Utility:-
    1.Click to Application
    2. Click Utilities -> Launch Disk utility
    3. Choose Erase option for selected volume/files

    But, these deleted data can be recovered by some Mac data recovery software so , I would like to suggest , you should use Mac Wipe utility of Stellar Drive ToolBox.
    It removes data beyond the recovery.
