How to Find Macbook Hard Disk Size?

Finding info about your mac, its hard disk space, RAM info etc. is not pretty hard to find but still confusing for first time users who just keep wondering on where to go to find everything related to the Hard disk in their macbook. Here is a tutorial on “How to Find Macbook Hard Disk Size?”

There are a couple options for this. One is the easy one to find how much free space is available in the hard disk in your macbook. You can see that when you open your Hard Drive folder from the desktop, it would be seen in the status bar in the bottom.
Check this image, and the status bar shows 8.61 GB available. This does not mean the total disk space of the Hard drive.

Other way, is to go into the System Profiler and checking for all the details. Here is how you can do that –
Go to the Apple icon in the top left of the screen, and in the list of options, click on “About This Mac” as shown –

In the Mac OS X version info window, click on the More Info.. button to go to the System Profiler which would be showing all the info you need about your Macbook and its hard drive.

In the system profiler that would open there, you can go the Hardware section, and in that, go to Serial-ATA tab which will give you all the Hard Drive information as following –

  1. The cool thing is, that you can find there all info about mac that you could possibly want to know…

  2. thanks for info and help

  3. I’ve looked there for mine, but I have some basic Intel info but no details about the disc. Does that mean I have to get another one and replace it? It’s not showing on the desktop nor in Disk Utility.

    The following is all it says on my MacBook 2,1

    Intel ICH7-M AHCI:

    Vendor: Intel
    Product: ICH7-M AHCI
    Speed: 1.5 Gigabit
    Description: AHCI Version 1.10 Supported

    but no more info like Hitachi etc……

    Bit worried as had so many probs with this MacBook. I’m running it off an external disk now, as I think the MacintoshHD is definately not coming back. Any thoughts??

  4. or, you know, just right click on the “hard drive” in the first picture n click on Get Info.

    you kinda left out the simplest solution 😛

  5. wicked helpfull thankss!!

  6. Hey thank you! that has been very helpful. I thought I must have been running out of disc space, but I still have just under half it’s full capacity remaining… that’s heaps.

  7. thank you 🙂

  8. thanks for the information!
    very useful in getting to the information i need but i still have a question:
    it tells me the capacity is 111.79, i’m sure that’s not the actual size so how can i find out the actual size?
