I copied and pasted this from the HP driver site for your laptop. All HP have the HP Tools partition. I deleted mine and put mine on a thumb drive. Why your getting the error that it is almost full is a bit confusing. Maybe you click a backup of some sort to use the E drive. I will tell you that my HP laptop runs a lot better once I uninstalled all the HP bloatware. If you have enough puter knowledge to do your own updates and keep track of driver updates then go to the uninstall window and have fun. I only kept 3 HP programs on my laptop and they are 3D drive Guard, Power Plan, and SimplePass Identity Protection. Everything else went by by.
The HP System Diagnostics must be run
from a FAT or FAT32 partition with a volume name of "HP_TOOLS". This
installer will give you the option to install to the HDD or a USB drive.
If you install to the HDD and the HP_TOOLS partition is not present,
the installer will prompt you to create the HP_TOOLS partition. If you
install to a USB drive, the installer will rename the partition on the
USB drive to HP_TOOLS. If you use a custom image, you can create the
HP_TOOLS partition manually with type FAT32 and make the volume name
HP_TOOLS. Caution - The HP_TOOLS partition is not protected and can
therefore be deleted. - Backing up the computer using the Windows®
Vista® Complete PC Backup does not back up the HP_TOOLS partition. For
these reasons, HP recommends that you do not place additional data on
the HP_TOOLS partition. Because the partition is not backed up,
corruption or failure of the partition will result in loss of all data
on the partition, plus loss of UEFI functionality. You can find more
