    Exclamation Can I format an internal hard drive for Mac without another working hard drive?
    My MacBook Pro's hard drive failed. I want to get a new one. The place I went said they charge for formatting a drive for mac. So I can pay them to format it, or do it myself.

    I know formatting an external hard drive is pretty strait forward, but I've never done an internal one.

    As my old hard drive is not working I cannot use it to turn my mac on and use the disk utility. Can I format the drive using my mac if the new hard drive is the only working hard drive I have for it?

    I have the install disk the Mac came with if I can use that for formatting.

    G'day and welcome to the forums.

    in short - Yes.

    Install the new drive, boot from install disc, select language, and then go to Utilities > Disk Utility > Erase and format the new drive Mac OS Extended (Journalled) and partition if necessary under Partition with GUID selected.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    yup, with the install disk in the drive, turn on computer while holding down the 'c' key. You can run disk utility from the install disk to format any connected drive
