Local Drives; Drive Z; Drive C And Flash - Wyse 9450XE Reference Manual

Local Drives

Administrators need to know the following information about local drives.

Drive Z

Drive Z is onboard volatile memory (Ms-ramdrive) of the thin client. Because drive Z is
volatile memory, it is recommended that you do not use this drive to save data that you
want to retain.
For Ramdisk configuration information, refer to "Peripherals" on page 41.
For information about using the Z drive for roaming profiles, refer to "Domain Participation"
on page 52.

Drive C and Flash

Drive C is onboard non-volatile flash memory. It is recommended that you avoid writing to
drive C. Writing to drive C reduces the size of the flash. If the flash size is reduced to
under 3 MB, the thin client will become unstable.
Caution
If the free flash memory size is reduced to 2 MB, the thin client image will be
irreparably damaged and it will be necessary for you to contact an authorized
service center to repair the thin client. It is highly recommended that 3 MB of
flash memory be left unused.
The Enhanced Write Filter (if ENABLED) protects the flash from damage and presents an
error message if the cache is overwritten. However, if this message occurs you will be
unable to flush the Enhanced Write Filter cache and any thin client configuration changes
still in cache will be lost.
Note
For information on the role of NetXClean in keeping the flash memory clean,
refer to "NetXClean Utility" on page 50.
Items that are written to the Enhanced Write Filter cache (or directly to the flash if the
Enhanced Write Filter has been flushed) during normal operations include:
• Favorites
• Created connections
• Delete/edit connections
