What is HP Tools Partition?

HP_Tools Partition is created by the system when the HP Tools utility is installed on your HP computer. It always store the computer’s diagnostic tools, which you can access by pressing F11 during OS boot and you can use to check for the failing hard disks. This HP_Tools partition is labeled E drive usually with a small capacity of  around 100MB. So it has much less available space than other partitions. Therefore, you’d better not save personal files, backups or program on HP_Tools drive.

However, many users have reported a problem about HP_Tools partition: I bought a HP laptop 3 month ago, I stored some files on my hard disk, but I have started getting a pops up saying that you are running out of disk space on HP_Tools (E:). Click here to see if you can free space on this drive. Then I clicked and the only thing listed is the empty Recycle Bin. I’m using Windows 10, and I just can’t solve it, please help.
