K.4.2 Rebuild Floppy Database
This utility attempts to rebuild any corrupt files that may exist on the floppy diskette.
Selection opens a pop-up window asking the user if they wish to continue. The options to
continue (OK) or Cancel are provided. This option is also available to the user via the
System Setup, and Additional System Setup menu selections.
K.4.3 Delete Hard Disk Database
This utility will delete the entire patient database. All other files on the hard disk will not
be affected. Selection opens a pop-up window informing the user that the entire database
will be deleted. The options to continue (OK) or Cancel are provided.
K.4.4 Delete Temporary Database
This utility deletes any temporary database copies that reside on the hard disk. Selection
will begin the deletion process. There is no option to cancel.
K.4.5 Reconstruct Database
The reconstruct utility is very similar to copying the hard disk database to floppy disks,
deleting the hard disk database and then copying the floppy disks back to the hard drive.
(The copy process differs from the restore process in that the copies only contain the
patient data and not the hard disk File Allocation Table, which is more susceptible to
corruption.) When reconstruct is selected, the Primary database is copied into a
temporary location on the hard disk drive rather than the floppy disks. The Primary
database at the original location is then deleted, and the Primary database at the
temporary location is renamed (moved) back to the original Primary location. The
“Cleanup Hard Disk Database” utility will remove any patients that have no tests. These
options are also available to the user via the
System Setup, and Additional System Setup
menu selections.
K.4.6 Secondary Database Utilities
Selecting this option provides nine more database utilities. Each utility is described below.
C Compare Database Sizes
This function does a file by file byte level comparison of both the Primary and Secondary
databases to verify that they are of the same size. This is a quick test that performs a count
of the number of files in each database. Under normal system conditions, the two
databases should always be equal. If they are not, the recovery option should be
performed.
C Verify Primary Database/Verify Secondary Database
