Pathways For Resolving A Hard Disk Database Failure – An Overview - Zeiss HUMPHREY 720i User Manual

DATABASE MANAGEMENT
REV. B 02/03 PN 51680-1
You will want to address the hard drive problem as soon as your schedule permits. The initial
attempt to fix the database problem may not be successful, however. If that is the case, your
next option is to use the rebuild utility (REBUILD HARD DRIVE DATABASE) found in System
Setup (ADDITIONAL SETUP). If rebuild is unsuccessful, as a last resort, you can restore the
patient database from backup magneto-optical or floppy disks. Figure 9-3 below summarizes
the pathway between database failure and problem resolution. The following pages lead you
through the necessary steps for each of the options discussed.
When faced with a hard drive database problem, your options are:
A. Attempt to fix immediately (FIX NOW).
B. Delay attempt to fix problem, continue patient testing, and save results to floppy disk only
(FLOPPY ONLY).
C. When time permits, engage rebuild utility (REBUILD HARD DISK DATABASE).
D. Restore database from backup floppy disks or magneto-optical disks, if above options fail
(BACKUP/RESTORE).
Caution: If a hard drive database failure occurs while attempting to save test
results, do not recycle power at this time. This action will cause you to lose the
results from the test just completed. Always elect either to fix the problem imme-
diately, or to temporarily save results to floppy disk until you have time to address
the database problem.
