If you modify the EWF using the command line, you must right-click the icon (you can then click anywhere on the screen to close the context menu) to refresh the status icon display. The status icon display is refreshed automatically when you make modifications through the EWF Control Panel applet. The EWF applet always reflects the current status.
Local drives
The following sections describe the local drives located on the thin client.
Drive Z
Drive Z is the onboard volatile memory (Ms-ramdrive)on the logic board of the thin client. Because drive Z is volatile memory, HP recommends that you do not use this drive to save data that you want to retain. For Ramdisk configuration instructions, see “HP RAMDisk” on page 11. For information about using the Z drive for roaming profiles, see “Roaming profiles” on page 31.
Drive C and Flash
Drive C is in the onboard non-volatile flash memory. HP recommends that you do not write to drive C, as writing to drive C reduces the free space on the flash.
ÄCAUTION: If the available free space on the flash memory is reduced to below 3 MB, the thin client becomes unstable.
The Enhanced Write Filter (if enabled) protects the flash from damage and presents an error message if the cache is overwritten. Items that are written to the write filter cache (or directly to the flash, if the write filter is disabled) during normal operation include Favorites, created connections, and deleted or edited connections.
