2 HP Write Filters The File-Based Write Filter (FBWF) and the Enhanced Write Filter (EWF) provide two distinct ways to provide a secure environment for your computer by protecting it from unauthorized writes to storage and file systems. FBWF operates at the file level, and EWF operates at the sector level. Only one write filter can be selected and active at one time.
● /displayconfig Displays all current configuration information for the write filter including filter state, protected volumes list, cache compression state, overlay cache threshold, cache pre-allocation status, and write through paths. ● /overlaydetail Displays detail on the current overlay contents for all protected volumes including file and folder contents and memory used. ● /addexclusion Adds a write through path to the exclusion list.
The FBWF Status icon displays the following states: ● Red lock: FBWF is disabled. ● Green lock: FBWF is enabled. ● Yellow lock: FBWF state will change on next boot. If you are logged on as an administrator, you can change the status of FBWF by right-clicking the icon and selecting the desired FBWF state. NOTE: Because the fbwfmgr.exe utility and the FBWF status service execute separate code, status changes made by fbwfmgr.exe are not automatically reflected by the FBWF status icon.
By including the EWF configuration interface in your configuration and building it into your image, you enable use of the EWF command line utility and the corresponding commands. To use the EWF command line utility, follow these steps: 1. Select Start > Run. 2. Type CMD in the Open field to access the system DOS prompt. 3. Click OK. 4. Type ewfmgr c: at the prompt. 5. Press enter.
The EWF interface includes the following buttons: ● Enable/Disable EWF Enables the Enhanced Write Filter so that data written to the protected media is cached in the overlays. Disables the overlay on the specified protected volume. ● Overlay Configuration Displays the overlay information and is a combination of the information supplied when executing ewfmgr.exe c: -Description and ewfmgr.exe c: -Gauge from the DOS prompt. ● Clear Boot Command Clears the boot command from the DOS prompt.
3 Configuration Local drives The following sections describe the local drives on your computer. Drive Z Drive Z (HP RAMDisk) is a virtual drive that is created from the system's physical RAM. The RAMDisk will look and behave like a standard fixed disk drive, but it is created at system startup and destroyed at system shutdown. Therefore, HP recommends that you do not store information or data on this virtual disk drive. The RAMDisk is volatile memory space set aside for temporary data storage.
Saving files The computer uses an embedded operating system with a fixed amount of flash memory. HP recommends that you save files that you want to retain on a server rather than on your computer. Be careful of application settings that write to the C drive, which resides in flash memory (in particular, many applications by default write cache files to the C drive on the local system). If you must write to a local drive, change the application settings to use the Z drive.
4 Applications Remote Desktop Connection The Remote Desktop Connection utility allows you to establish connections to a Windows Terminal Server or to access remote applications by using Microsoft Remote Desktop Protocol (RDP).
