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.
The following items are stored on the RAMDisk:
●
Browser Web page cache
●
Browser history
●
Browser cookies
●
Browser cache
●
Temporary Internet files
●
Print spooling
●
User/system temporary files
You can also use the RAMDisk for temporary storage of other data (such as roaming profiles) at the
administrator’s discretion.
Use the RAMDisk Configuration dialog box to configure the RAMDisk size. If you change the size of
the RAMDisk, you will be prompted to restart for the change to take effect. To permanently save the
change, disable the write filter cache or issue the
-commit
command during the current boot session
before restarting.
NOTE:
The default optimal RAMDisk size is 64 MB. The maximum RAMDisk size that you can set
is 96 MB. The minimum is 16 MB.
Drive C
CAUTION:
If the available free space on the flash drive is reduced to below 3 MB, the computer
becomes unstable.
A write filter is used by the computer for security and to prevent excessive flash write activity.
Changes to the computer configuration are lost when the computer is restarted unless the write filter
cache is disabled or a
-commit
command is issued during the current boot session. For additional
information, refer to
.
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
