The short answer is that the hard drive in your computer is compressed. Compressing a computer hard drive lets you fit more information on a drive, but requires an area (known as H partition) to be created for files that will not work while compressed.

Can I remove H safely?

Compressing the hard drive is usually permanent, and although it can be possible to uncompress the drive, it is an unreliable process. If you want to only have a C: drive or if you are running into issues with your compressed hard drive, we recommend you erase your computer and start over.

The H drive is the portion of the hard drive that is not compressed.
