C If the rebuild fails, try viewing the diskette on a PC. Proceed to the “A” drive and
attempt to look at the directory. You cannot view individual patient files, but should
be able to see the directory. The directory will consist of files like PATS.DAT,
PATS.IDX, PDB.DAT,
RXS.DAT, etc. If the diskette is part of a backup that was made using the
Backup/Restore function you will only see BACKUP.PDB
C
If the directory cannot be seen or looks damaged, try executing scan disk on the PC.
It has been reported that this may partially repair a corrupted floppy.
C
If all of the above has failed and there is not a duplicate of the diskette, contact
Technical Support for additional assistance. Also, advise your customer to format
and begin using a new diskette.
K.6 Hard Disk Drive - Troubleshooting Dialogue
The following dialogue is intended to assist you in solving database related problems. This
is only one approach; each situation is unique. Ultimately, it is the service engineer’s
choice to determine which utilities should be used and which approach should be taken.
The dialogue utilizes the “5 Rs” of database recovery (Appendix K.3).
If the hard disk drive database is corrupted or inaccessible, the customer will usually report
the following on-screen error message:
“Hard Disk Database is Not Accessible - Would You
Like to Recover?”
or
“A hard drive database failure has occurred. You can only use a floppy
disk until the hard disk drive database is repaired.”
Check/Perform the following:
C
Does the customer have a backup? This can either be copies, a backup made using
the Backup/Restore function, or a magnetic optical disk.
C
Check the System Log for database-related errors. The hard drive database will be
indicated as device 4.2. In general, errors like “hard drive error” or similar errors are
associated with the hard drive patient database and/or the hard drive subsystem
(hard disk drive, hard drive cabling, and/or the controller on the CPU PCB). Refer to
Section 5 for hardware/diagnostic troubleshooting procedures.
C If a floppy diskette is inserted in the floppy drive, remove it and turn the instrument
power Off/On (Reboot). Then make a second attempt to view the hard disk
database. Sometimes a problem with the floppy diskette may be indicated as a
problem with the hard disk drive or database.
C Was the option to Recover attempted? If not, attempt to recover the database. The
recover option will normally be displayed either after the reboot or if you attempt to
access the database. Select the
“Fix Now”
button in the Fix Now/Floppy Only
alert.
C
If the recover option fails, proceed to the Diagnostics/Calibration Menu and select the
Reconstruct database option. The Reconstruct utility can only be attempted if the
database can be opened. If it cannot then use Rebuild to perform
rebuild/reconstruct.
C
If reconstruct fails, attempt a hard disk Rebuild if the database can be opened.
C
If the rebuild fails, and the customer DOES NOT have a backup of their database
available, replace the hard disk drive with a new drive. Contact the Technical
