Error: Low Disk Space. You are running out of disk space on HP_Tools (Windows 7)
This document applies to HP notebook computers with Windows 7.
Low disk space error notifications appear periodically, or when you try to open the HP_Tools drive.
Why do these errors occur?
The purpose of the HP_Tools drive is to store all the files needed for system diagnostics. The HP_Tools drive is actually a partition on the main hard drive in your computer - not an actual, physical drive. It has much less available space than Drive (C:). If you use the HP_Tools drive to store files, or if a backup or restore program uses the HP_Tools drive to store files, the drive quickly becomes full and can cause serious problems when you need to use system diagnostics.
Do not store files on the HP_Tools drive. The only files on the HP_Tools drive should be related to system diagnostics. The HP_Tools drive should contain mostly free space:
How can I fix these errors?
To stop Low Disk Space errors, ensure that System Protection is turned off for the HP_Tools drive, and remove files that are not related to system diagnostics from the drive. Perform the following steps:
CAUTION:Make sure you have created a set of recovery discs before using these steps. If the system stops responding, recovery discs can be used to perform a system recovery.
- Click Start , and then right-click Computer.
- Select Properties.
- Click System Protection from the left side of the window.
- In the "Protection Settings" section, look for the HP_Tools drive in the list of Available Drives. If the drive is listed, check whether protection is turned off or on for the drive:
- Click Start , and then click Computer.
- Before you can remove any backup or restore files and folders that might be stored on the HP_Tools drive, you need to be able to view hidden system files, as follows:
- From the Explorer window, press the Alt key on the keyboard to make the menu bar appear in the window.
- Click Tools, and then select Folder options.
- Select the View tab.
- Select Show hidden files, folders, and drives, and remove the selection from Hide protected operating system files. If a Warning message appears, click Yes or OK to confirm. Click OK to close the Folder Options window.
- From the Explorer window, double-click the HP_Tools drive.
- If a Window opens stating "You don't currently have permission to access this folder," click Continue.
- If you previously created or copied any files into the HP_Tools drive and you want to keep them, copy the files to another drive - such as the C: drive.
- Find and delete any files that you previously saved in the HP_Tools drive. Select the files or folders, and press Shift + Delete to permanently remove the files.Look for any folders that might be associated with a backup program on your computer. If a backup program is saving files to your Recovery drive, move the folder to a different location, and change your backup settings so that the files save to a different drive.CAUTION:Do not delete any files that are associated with system diagnostics! Do not delete the items HP_WSD.dat, PSF_Rep, Recycle Bin, or the Hewlett-Packard folder! Doing so can prevent system diagnostics from functioning correctly. If you are not sure, do not delete the file.
- Several confirmation windows open. Click Continue, and Yes until the files and folders are deleted.
- Set Windows Folder Options back to their original setting as follows:
- From the Explorer window, press Alt to view the file menu.
- Click Tools, and then select Folder Options.
- Select Don't show hidden files, folders, or drives and select Hide protected operating system files.
- Click OK.
- Close Explorer. The Out of Disk Space errors should no longer appear.
