HP T5720 Quick Reference Guide for Microsoft Windows XPe-based Thin Clients - - Page 15

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 32. For information about using the Z drive for roaming profiles, see Roaming profiles on page 10. Drive C and flash Drive C is in the onboard flash drive. HP recommends that you do not write to drive C, as writing to drive C reduces the free space on the flash. CAUTION: If the available free space on the flash drive is reduced to below 3 MB, the thin client becomes unstable. A write filter is used by the thin client for security and to prevent excessive flash write activity. Changes to the thin client configuration are lost when the thin client is restarted unless the write filter cache is disabled or a -commit command is issued during the current boot session. See the write filter topics in Enhanced Write Filter Manager on page 29 for instructions to disable the cache. Enable the write filter when you no longer want permanent changes. Saving files CAUTION: The thin client 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 thin client. 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. To minimize writing to the C drive, update configuration settings as described in User accounts on page 11. Mapping network drives You can map network drives if you log on as either Administrator or User. ENWW Local drives 9
