Testdisk for mac mac os x#
Once I had the GPT looking like my Testdisk output, I used the w command to write the GPT and rebooted into the glorious Mac OS X desktop I know and love. TestDisk is a recovery utility that help users to get back data lost from their hard drives. As a result, these programs are designed for support personnel and experienced Mac users. They are used on the command line in the Terminal.
Obviously, the big one in the middle is going to be the most important to you to get yourself booting again. TestDisk download contains TWO programs - TestDisk and PhotoRec. Create a new table, change your default sector size from 2048 to 1 using the expert settings (since you know your partitions precisely), and use the well-documented commands to make a new partition table. Gdisk is another command line tool in Parted Magic that will make your GPT for you. Use pdisk (mac) or parted (linux) to recreate the missing partition using values displayed by test disk" TestDisk & PhotoRec cannot be removed completely from Mac, there are still some files and components leaving on the computer. Unfortunately, Testdisk will not write these Apple partition tables, giving an error: I had to make a bootable CD that could run Testdisk and gdisk, and the Parted Magic recovery environment on the Ultimate Boot CD worked great for me:Īs earlier in the thread, I used Testdisk in Parted Magic to figure out what my GPT partition table should look like. Even though it lacks an intuitive graphical user interface, TestDisk is still one of the best data recovery software options for Windows, Mac, Linux, and many additional operating systems. I deleted my GPT partition table on my system Mac OS X hard drive using a misguided "clean" command with diskpart while trying to install Windows 7 on a bootcamp partition. This is a very old thread, and I'm sorry-but I just went through this and have a solution that I couldn't find immediately.
