Chapter 5, Memory Cards/Mass Storage
Copying Files Using IBASIC Commands
Copying an Entire Volume
An entire volume can be copied from one mass storage device to the same type of
mass storage device using the volume copy form of the COPY command. The
destination volume must be as large as, or larger than, the source volume. The
directory and any files on the destination volume are destroyed. The directory size
on the destination volume becomes the same size as the source media. Disc-to-
disc copy time is dependent on the mass storage device type. The volume copy
form of the COPY command was designed to copy like-media to like-media and
like-file-systems to like-file-systems. For example, to copy the entire contents of
one internal RAM disk to another internal RAM disk, execute the following
IBASIC command from the TESTS (IBASIC Controller) command line:
COPY ":MEMORY,0,0" TO ":MEMORY,0,1"
NOTE:
Using the volume copy form of the COPY command can produce unexpected results. For
example, using the volume copy form to copy the contents of a
64-KB SRAM card to an external GPIB 630-KB floppy disk will result in the external floppy
disk having a capacity of only 64 KB when the volume copy is finished. Furthermore all files
on the floppy disk before the volume copy was executed will be lost and are not recoverable.
Additionally, the file system type on the source media (LIF or DOS) is forced onto the
destination media. Caution should be exercised when using the volume copy form of the
COPY command.
The Test Set only supports the following types of volume copy using the volume
copy form of the COPY command:
1. Like- media to like-media (RAM disk to RAM disk, external floppy to external floppy,
2. Like-file-system to like-file-system (DOS to DOS, LIF to LIF)
All other types of volume copy are unsupported and will produce unexpected
results or system errors.
Using wildcards in the COPY command can eliminate the need to use the volume
form of the COPY command. Refer to the HP
Handbook for further information on wildcards and their use in the COPY
command.
