Restoring the Hard Disk Database
If all previously cited methods to correct the database pr
oblem have failed and you are faced with
an unrecoverable database, the only option remaining is to restore the hard disk database from a
USB storage device, backup floppy disks, or the network file server (if you have licensed HFA-NET
Pro software). Detailed instructions follow. If you need further assistance after attempting this
process, call Carl Zeiss Meditec Customer Care at 1-800-341-6968. Outside the U.S., contact your
local Carl Zeiss Meditec distributor.
CAUTION: HFA II-i series
system software 5.x creates a different database structure
that is not fully compatible with previous software releases. You can only restore a
version 5.x database backup to an HFA II-i version 5.x instrument.
