The floppy-only option will allow the instrument to save only to the floppy disk drive. This
enables the operator to continue to save patient exams until a service technician can repair
the hard disk drive problem. The floppy-only option would normally be selected if the
Recover option has failed, the user has just completed a test and immediately needs to
save it to disk, or does not currently have the time to wait for the Recover option to
complete.
#
Reconstruct (or “Cleanup” on Additional Setup)
The hard disk Reconstruct option is described in Appendix K.4, Database Utilities.
#
Rebuild
The hard disk Rebuild option is described in Appendix K. 4, Database Utilities.
#
Restore
The restore option is often the last step taken in database recovery. Either the magnetic
optical disk or the floppy backup is restored to the hard disk.
K.4 Database Utilities
In the event of a patient database problem, there are a number of software features
designed to protect the integrity of the patient database. These utilities, described below,
can be accessed and activated via the calibration portion of the software. Refer to Section
4 for access details.
The Database option provides six primary utilities which can be used to either rebuild,
reconstruct or delete the patient database. Refer to Section 9 (Database Management) in
the Humphrey Field Analyzer II - i User’s Guide.
K.4.1 Rebuild Hard Disk Database
This utility attempts to rebuild the corrupted index files and reconstruct the checksums that
may exist on the hard disk. Selection opens a pop-up window warning the user that
rebuilding may take a very long time. The options to continue (OK) or Cancel are
provided. This can be a lengthy process depending on the number of files on the hard
disk drive. This option is also available to the user via the System Setup, and Additional
System Setup menu selections. The rebuild function will first attempt a simple recovery if
it detects a database failure. If recovery succeeds, rebuild is done. Otherwise, it starts
rebuild. If rebuild fails but the primary database can be opened then a reconstruct is
automatically attempted.
NOTE: When rebuild of the primary database succeeds either the first attempt or after
subsequent reconstruction the primary database is copied to the secondary database. The
customer will see “Ensuring Database Integrity.....” along with a progress bar.
