File Functions
11–11
The format function can be used to erase all data from the external memory
card and from some of the internal memory devices. When you pick
Format
in the File menu, a warning message box appears on the screen as shown in
Figure 11.10.
NOTE 1: If the Format item in the File menu appears in shaded type, the
format function for the selected device is not available or applicable.
Figure 11.10 Format Warning Message Box
If you intend to perform the format function, pick the button; if not, pick
the button to exit the format function.
If you pick the button, two messages will appear on the screen, usually
in rapid succession: Format in Progress , and Format Complete .
NOTE 2: When formatting is under way for the V1: or V2: device, the
Pass/Fail LED on the CVIM2 front panel alternates between orange and
green until formatting is completed.
NOTE 3: When the files “ .passwd , “ Except.lvl ,” and “ Except.str ” are
stored in the EE: device, they are not destroyed by a format operation on the
EE: device. These files are copied to the RM: device before the format
operation begins, and they are restored to the EE: device when the format is
complete. (If the RM: device has insufficient space for the copy operation,
the files will be copied instead to the V2: device; however, if neither device
has sufficient space, the format operation will be aborted.)
Note that a tilde ( ~ ) is added to each filename before being copied to the
RM: or V2: device. Thus, the file “ Except.lvl ” would be copied to the RM:
or V2: device as “ ~Except.lvl ”, thereby preventing it from overwriting a file
that was previously stored there under the “ Except.lvl ” filename. The tilde is
removed from the filename when the copied file is restored to the EE:
device.
