My PC came with a 1TB SSD only. (old C: drive) I had a 500GB SSD added and made that the new C: drive and made the old 1TB SSD the new D: drive

There are no files on D: drive. Yet 47GB is taken up. Presumably by old system files from it being the previous C: drive?

  1. Do you think that's what is taking up that space? And more importantly
  2. How can I reclaim that space?

Macrium Shows SSD Space taken up on "empty" D: Drive.

    There are no files on D: drive. ----- Do a complete format and see if space is reclaimed that way

    Careful, it may still be the boot and recovery drive, depending on how the new drive was created as the new C:.

    Does this answer your question? How can I visualize the file system usage on Windows?

  • @John I just formatted it after your suggestion. It's the same exact size.

  • Likely then, that is just the available space on the drive.

Found the culprit.

I had done "Create a system image" using Windows 10 Pro. Created a system image of the C: Drive onto this D: drive. I copied that image to my external drive and deleted the image from this D: drive.

However (I'm guessing maybe because they were system-type files) it just didn't really delete it. I deleted it, emptied the trash, and restarted the PC, but it did not clear that space from the D: drive.

But then reformatting the D: drive did clear the space.

  • Windows was aware of hidden files, associated with the shadow volume, which is associated with creating system images with Windows 7 Backup. By deleting the image the way you did, you orphaned the information, one of the reason's I don't use the built-in software to create images of my system disks.

  • @Ramhound Thank you! I am learning this lesson right now. I just tried repairing from my saved Image, which I had put on a USB stick. Windows could not find it. I assume it's missing the "mediaID.bin" file. ALSO... super lame. That you cannot change the name of the folder containing the Windows Image. I had changed to WindowsImageBackup 001, 002, 003 etc. and made notes of my incremental Images. But no, to restore an image using Windows, that folder can only be called "WindowsImageBackup". So no way of keeping track of which images are which. Just dumb all around. Will stick with Macrium etc.
