Windows 10: My 4TB hard drive shows 957gb is being used but if I right click all folders it’s only 850gb?

I’m looking at windirstat and it’s saying the same thing only 850gb being used.

Ccleaner shows nothing when I try to clean the drive too

New 4TB Hard Drive Read As 1.6TB

The 4TB drive only shows 1.6TB, there always are two reasons for that:

1.The 4TB hard drive has been initialized to a wrong partition table. If you find a formatted hard drive not showing full capacity, which is mainly because you format the
4TB hard drive to MBR partition table. As we all know, MBR partition table cannot address to the space that exceeds 2TB. As a result, to use a full capacity of a hard drive that is larger than 2TB, you need to initialize it to GPT partition table
via
an MBR to GPT converter.

2.The 4TB external hard drive does not connect correctly. Some portable hard drive and USB hard drive are designed to connect a PC via a USB port. If you install the USB hard drive to your computer, the hard drive capacity detecting may
become an issue. An accepted explanation is the controller board of USB hard drive breaks the 2TB limitation, yet Windows internal device controller does not. Therefore, you need to additional hardware to make the installed USB/portable hard drive showing
full capacity. In that case, all you need to do is connecting the 4TB USB hard drive via USB port.

Hard Drive not Showing

Hi Lori,

Thank you for posting back.

• How are you connecting the Hard drive to your computer?
• Have you tried connecting the hard drive to a different computer and check if it works?

It's possible that your USB drivers are corrupt. I suggest you to try the following steps and check.

• Press Windows Key +R and type
  devmgmt.msc to open Device manager.
• Expand Universal Serial Bus controllers
  at the left bottom.
• Right-click the first USB controller under Universal Serial Bus controllers, and then click on
  Uninstall to remove it.
• Repeat these steps for the entire USB controller under Universal Serial Bus controllers.
• Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.

Keep us posted with the status of the issue to assist you further.

Thank you.
