How much free disk space does this MacBook Pro's HDD really have?

The entire drive is 750 GBs and formats to just under 700 GBs of which 27% is used. So you can't have 750 GBs of free space, but you may have 750 GBs of total capacity depending upon what you use to obtain that information.

According to the df command you have 698 GBs of total formatted space of which 185 GBs is used. This is using Base2 math. The manufacturer's advertised space is 750 GBs which uses Base10 math. The latter makes the drive seem larger than it would be as seen on the computer.

If you can see the Macintosh HD icon on the desktop you can use Get Info by menu option

or keyboard shortcut, to see the total free & total used capacities of a storage device drive.

To make an invisible internal or attached storage drive or device appear on the desktop

you can use the Apple menu, choose Finder, note Preferences in its drop-down menu:

Then use Command + i = to Get Info from the Macintosh HD main or other storage drive.

Hopefully this may be helpful in regard to learning present and future access of your computer system.

Good luck & happy computing! 🙂

I'm sorry, but no screenshot. Here's what you need to do:

To post screen shot do this:

1. Press COMMAND-SHIFT-4 which will change the cursor to crosshairs.
2. Hold down the mouse button and use the crosshairs to select the part of the screen you wish to capture.
3. Release the button and the image will be saved to your Desktop.
4. Click on the Camera icon in the toolbar of the forum message editor.
5. Drag the image onto the Choose File button and click on the Insert button.

The information from using COMMAND-I shows that the 750 GBs is the drive's Capacity/Size using Base10 math. The OS converts the Base2 information to Base10, hence why it differs from using the df command in the Terminal. There is nothing wrong with the data being displayed by both, just a difference in math base.

Base10 1GB = 1000 x 1000 x 1000

Base2 1GB = 1024 x 1024 x 1024

The difference is about 7% which accounts for the 50 GB difference between 750 and 700 GBs.

Another less technical way to tell the capacities of hard drive or SSD storage

internal or attached to a computer may be through the use of Disk Utility in

the OS X. Usually most information will show on those drives attached to the

logic board if they happen to be prepared for use as bootable system drives.

Those prepared with installer for running OS X have more partitions, re: Recovery

and other sections where special functionality are available for the system, show

more details. And some clone utilities may not reproduce all of these in their demo

or unpaid version; so if you want to make a complete backup copy of a running OS

X system, be sure this aspect is correctly duplicated on the clone.

Anyway, it appears you have a few replies...! 🙂
