How do I install a RAM drive on an existing Metadefender Core installation?

Modified on Sun, 17 Jul, 2016 at 9:20 PM

When installing Metadefender Core for the first time, you will be given the option to install the RAM drive which will automatically configure itself for your installation.

If you wish to set up and configure the RAM drive for Metascan servers that are already running without reinstalling Metadefender Core, please follow the steps below:

  1. Download the RAMdrive ZIP file and extract it to a permanent location.
  2. Enter the folder that corresponds to the number of bits for your Windows installation. For most customers, this will be the '64' folder.
  3. Run 'ramdrv_install.exe' as Administrator.
  4. Run 'ramdrv_restart.exe' as Administrator.
  5. Check your computer for the existence of an 'O:' drive. Note: If this is not present, restart the machine.
  6. Open Windows’ Device Manager and under 'RAM Drive', double-click 'OPSWAT Secure RAM Disk'. Note: Within this menu, you can configure the size of the RAM drive, please read this article to understand the RAM drive constraints should be set on system
  7. Allocate as much capacity as you feel comfortable, the larger the files you tend to scan are, the larger you will want the RAM drive to be. Note: Metascan will not allow you to scan archives larger than half the available temporary storage. To get around this limitation, we recommend setting a secondary temporary directory.
  8. Open the Metascan Management Console and navigate to 'Workflow' -> 'Scan Configuration'.
  9. Set the 'Secondary Temp Directory' to the current value of 'Primary Temp Directory', typically 'C:\Windows\TEMP\'.
  10. Set the 'Primary Temp Directory' to 'O:\'.
  11. Also under the 'Workflow' tab, navigate to 'Archive Handling' and ensure that you are happy with the current archive settings as they may have been lowered during the previous steps.
  12. If you run a local antivirus with real-time protection, add an exclusion for the 'O:' drive.
