Using External Disk Drives
Using External Disk Drives
The Test Set supports only HP-IB external disk drives. Certain configuration
information is required by the Test Set to access external disk drives.
The I/O CONFIGURE screen’s HP-IB
Mode field must be set to Control any time
an external disk drive is used by the Test Set.
To load files from the TESTS screens or NMT Signaling Decoder screen, the
disk’s mass storage volume specifier must be entered in the
External Disk
Specification
field on the TESTS (External Devices) screen (for example,
:,702,1).
Initializing External Disks
All new external disk media must be initialized before it can be used to store
information. External disk media can be initialized for either LIF (Logical
Interchange Format) or DOS (Disk Operating System) format using the Test Set.
(See
"DOS and LIF File System Considerations" on page 220.)
External disk media can be initialized from the TESTS (IBASIC Controller)
screen by inserting the new media into the external disk drive and executing the
following IBASIC command:
INITIALIZE "<volume type>:<external disk mass storage volume
specifier>"
where the <volume type> can be LIF or DOS
For example:
INITIALIZE "DOS:,702,1").
To verify that disk media has been properly initialized, execute the IBASIC
command:
CAT "<external disk mass storage volume specifier>"
For example:
CAT ":,702,1"
NOTE: The IBASIC INITIALIZE command defaults to LIF format. Any media (RAM Disk, SRAM
Cards, External Hard Disk Drive or 3.5-inch floppy) formatted using the default conditions of
the INITIALIZE command will be the LIF format and will be unusable in the Test Set, except
for IBASIC mass storage operations. Refer to "Initializing Media for DOS or LIF File
System" on page 223 for information on formatting media for the DOS file system.
