I have a C drive and H drive, what is H?
The hard drive within your computer is compressed. Compressing a computer hard drive allows you to get more information on a drive, yet at the same time requires an area (known as H partition) to be created for files that will not work while compressed (H drive being the portion of the hard drive that is not compressed).
Can I remove H safely?
Compressing the hard drive is usually permanent and although it can be possible un-compressed the drive it often causes more problem than its worth. If you want to only have a C: drive or if you are running into issues with your hard drive compressed we recommend you erase your computer and start over.
