3-10 Disk Drives and Files
MX2 Reference Guide Revision A MX2A137REFGD
Drive D
Drive D is a RAM disk drive. By default, this drive resides in extended
memory and is sized 1MB less than the total RAM in the unit.
Drive D can be used for short-term data storage. Programs that need to
be loaded into memory and then removed from memory quickly can also
be located there. The drive can also be used for scratch disk space or
temporary files.
The MX2 preserves the data on drive D between warm or cold boots by
checking for an existing RAM disk. However, only minimal checking is
performed on any disk that is found. If something happens to a unit and
data integrity becomes questionable, you should use the CHKDSK utility
to detect and correct errors on drive D.
Drive E
Drive E is the ATA flash card. The PC card looks like a hard disk drive
to the operating system and the user. More flexible than flash disk drive
C, it can be used for safer and more permanent bulk storage of batch
data than the RAM disk (drive D). This drive exists only on systems
configured to use ATA flash cards.
Drive E could also be a peer-to-peer or client-server network drive that
is accessed through an RF or Ethernet network card link. This option
allows the developer to make many network drives (drives E, F, etc.)
available to applications.
