Mac OS X Mavericks cannot detect exact HD capacity size

Asked By 0 points N/A Posted on -

I have a MAC OS X Mavericks and when I try to connect to the new 3TB hard drive, it does not show me the right hard drive space. How can I make the OS read the correct hard drive capacity? Are there any limitation issues on computers reading a 3 TB hard drive?

Mac OS X Mavericks cannot detect exact HD capacity size


In order for your Mac to recognize the hard drive's full capacity you must format the hard drive.

Hard drives that are bigger than 1 TB have a conflict with the OS X Maverick operating system. It's true, it does not show you the correct HDD space because the operating system demands that you format it so that it can read it from start to finish and create an exact calculation of its size.

Format you new drive by plugging it in and taking these next steps:

1. Open the Disk Utility program located in Applications/Utilities.

2. A new window will appear that will allow you to select the 3 TB drive.

3. Select the desired drive and then click on the Erase tab.

4. There will be a drop-down option at the Volume Format section, and you must choose the Mac OS Extended (Journaled) option.

5. After the selection, press the Erase button and it will format your drive.

After the process is completed, you will be able to use your hard drive to it's full capacity.
