The Clearwell product relies on having a certain amount of free space on both the C: and D: drives. The minimum suggested free space is 10GB on the C: drive and 500GB on the D: drive. If the Clearwell system runs out of space the issue may present itself in several different ways.
Note: In rare situations, if the Clearwell appliance runs out of disk space during processing, this can result in database integrity issues that cannot be corrected without restoring from a case backup. Because of this, it is recommended good practice to perform a case backup before any new data processing (this includes running an OCR job). The Clearwell Release Notes mentions the following: "Check the disk space in your database before you start case processing: If the database runs out of disk space during case processing, increase the disk space and either restart case processing or restore the case from a backup and resume processing."
In the log files a message may appear like
Not enough free space available or the user may encounter IE 404 error.
Please consult the following article if a disk space error is occurring during a Case backup or archive: https://www.veritas.com/support/en_US/article.TECH222300
For the C: drive Start by doing typical Windows Maintenance.
1.Clear existing Window Problem Reports.
Look in the following directories: (these are hidden folders)
To remove these files, go to "Control Panel > System and Security > Action Center > Maintenance > View reliability history > View all problem reports" and click "Clear all problem reports". To prevent future problem reports, go to "Control Panel > System and Security > Action Center > Maintenance > Settings > Change report settings for all users". These steps are also included in the Clearwell Installation Guide.
It is also recommended to disable Windows memory dump. To disable this, go to "Control Panel > System and Security > System > Advance System Settings" and click "Settings". In section "Startup and Recovery", under the "Write debugging information" drop-down menu select "(none)". These steps are also included in the Clearwell Installation Guide.
2. Run Windows Disk Cleanup tool (cleanmgr.exe).
Look in the following directory: (this is a hidden folder)
This directory contains temporary files left behind from the installation of Microsoft Office (see http://support.microsoft.com/kb/825933). Note: Never delete the files in this folder by using Microsoft Windows Explorer.
To clear the files in this directory, use the Windows Disk Cleanup tool. This tool (cleanmgr.exe) is not present by default in Window Server 2008 R2. Follow the steps here to install it. Once installed, launch the tool by running "cleanmgr.exe" from the command prompt. This tool enables the user to clean up various files, including Temporary Internet Files and the Recycle Bin. To clear the C:\MSOCache directory select "Office Setup Files".
3. Delete temporary Internet Cache (for each user account)
4. Review the "Users" directory and clean items to help free up space.
5. Using a third party tool like TreeSize can help find where the space is being taken up.
6. C:\CW may also contain a copy of eDiscovery sample data that may no longer be needed
Here are some helpful hints to clear space off the D: drive
1. From the Clearwell User interface navigate to the System > Jobs
Set the settings to most inclusive and delete any old jobs that are complete and not needed any more.
2. Move the backup location off to a network location. In order to move data use robocopy as described :

AND reconfigure the location of the backupdir:

4. If there are any old lingering versions of Clearwell under D:\CW\Vxx consider copying them off and delete them as well. There is really no need to have them there as the new environment cannot be downgraded to an older version.
5. Check if there are any legacy log zip files generated by the system located in folder "D:\CW\Vxx\scratch\uploader\esadb". These zip files are produced by the system to be uploaded when web access is not possible for the appliance and so may build up over time.
6. If there are case sources on the D drive that is not a best practice. Consider moving the sources off to a network location. Follow the process for moving the source off.
