If you’re wondering why a new computer has less free space than its hard drive specifications would lead you to believe, there’s a good chance some of that is taken up by a separate recovery partition. Laptops and desktop computers often come with several partitions, including a hidden recovery partition.

To adjust the amount of hard drive space used by the shadow copy service (System Restore and Previous Versions of files), follow this guide: Make System Restore Use Less Drive Space in Windows 7 The difference above looked more like 7 GB, but that can be explained by rounding. Run the following command in the Command Prompt window:Īs we can see in the command below, about 9 GB of space is used in our hard drive by the Windows Shadow Copy Storage. You’ll need to run it as Administrator – to open a Command Prompt window as Administrator, search for Command Prompt in the Start menu, right-click the Command Prompt shortcut, and select Run as administrator. To view the exact amount of storage used by shadow files on every hard drive attached to your system, you can run the command below. The shadow storage contains System Restore points and previous versions of files for the Previous Versions feature in Windows Explorer. Files in Windows’ aptly named “shadow storage,” also known as “shadow copies,” don’t appear here. It turns out that certain types of files don’t appear in Windows Explorer. That’s a difference of 7 GB or so – where did all those GBs go?

Here, we have 272 GB worth of files on our C: drive – but Windows is using 279 GB of space. The amount of space used by files doesn’t match up with the amount of used space on your hard drive.

However, if you select all the files on your C: drive (including hidden files and Windows system files), right-click them, and select Properties, you’ll notice something odd.

If you right-click your C: drive in Windows, you’ll see a certain amount of space referred to as “Used Space” – in the screenshot below, the hard disk contains 279 GB of files. You’ll probably notice something odd about the amount of free space your hard drive contains, if you look closely. Why Your Computer Shows the Wrong Amount of Free Space

#WHY IS MY MAC SYSTEM STORAGE 400GB UPDATE#
If hard disks were advertised in terms of the amount of space they actually contained when you connected them to your Windows computer, a 1 TB hard drive would be labeled a 931 GB hard drive instead.Īlternatively, Windows could update their UI to use the correct definition of gigabyte–other operating systems, like OS X, have already changed their representation to correctly state the right amount of space. That’s a difference of nearly 35 GB over what the average buyer would be led to believe a hard drive contains. Keep in mind that the hard drive manufacturers are using the accurate description of the terms–the prefix giga, for instance, means a power of 1000, whereas the correct term for powers of 1024 is gibibyte, though it isn’t often used. Unfortunately, Windows has always calculated hard drives as powers of 1024 while hard drive manufacturers use powers of 1000. When you’re buying memory, a KB is 1024 bytes, a MB is 1024 KB, and a GB is 1024 MB. However, manufacturers of RAM don’t sell it in even groups of 1000 – they use groups of 1024. The hard disk manufacturer thus advertises the disk as a 500 GB hard disk. To a hard disk manufacturer, one KB is 1000 bytes, one MB is 1000 KB, and one GB is 1000 MB. There’s also some overhead required when Windows formats your drive, for the file system and boot data, though in comparison to today’s large hard drives, it’s not a lot. The reason for this difference lies in the way hard drive manufacturers advertise their devices, versus the way Windows computers actually use the storage devices. If you’ve paid attention to hard drives, USB flash drives, and other storage devices, you may have noticed that they always have less space than promised once they’re formatted.
