Use the Hard File Smart Test when the system management tool has detected a hard file SMART alert.

The Smart test does the following:

v Interrogates IDE devices for support of the SMART instruction set. v Issues a ENABLE SMART command to make sure SMART functionality is

active.

v Checks the SMART RETURN STATUS command to determine if any thresholds

have been exceeded.

If thresholds have been exceeded, an error message is shown, and the test fails. If no SMART is supported by the drive, the test returns with ″N/A″.

Quick and Full erase - hard drive

The Diagnostics program offers two hard drive format utilities:

v Quick Erase Hard Drive v Full Erase Hard Drive

The Quick Erase Hard Drive provides a DOS utility that performs the following steps.

v Destroys the Master Boot Record (MBR) on the hard drive. v Destroys all copies of the FAT Table on all partitions (both the master and

backup).

v Destroys the partition table. v Provides messages that warn the user that this is a non-recoverable process.

Chapter 3. Diagnostics 15

The Full Erase Hard Drive provides a DOS utility that performs the following steps.

v Performs all the steps in Quick Erase. v Provides a DOS utility that writes random data to all sectors of the hard drive. v Provide an estimate of time to completion along with a visual representation of

completion status.

v Provides messages that warn the user about non-recoverable process.

Important: Make sure that all data is backed up before using the Quick or Full Erase functions.

To select the Quick Erase or Full Erase Hard Drive utility, use the following procedure.

1. Select the UTILITY option on the toolbar and press Enter.

2. Select either the QUICK ERASE or FULL ERASE HARD DISK option and

follow the instructions.

Use the Iomega Zip Drive Test to test the Zip drive and the drive interface. The test takes about 20 seconds to run.

The default tests the following:

v Controller v Max Seek (50 times) v Random Seek (300 sectors)

Asset EEPROM backup

When replacing a system board, this utility allows the backup of all Asset information from the EEPROM to diskette. This utility also restores data to the EEPROM from diskette after replacement of the system board.

To run this utility, use the following procedure.

v Select Utility v Select Asset EEPROM Backup v Follow instructions on screen.

Viewing the test log

Errors reported by the diagnostic test will be displayed by the program as a failed test.

To view details of a failure or to view a list of test results, use the following procedure from any test category screen.

v Press F3 to activate the log file. v Press F3 again to save the file to diskette or F2 to print the file.

When to use the Low-Level Format program

Notes:

1. The low-level format is not available on all diagnostic diskettes.

2. Before formatting the hard disk drive, make a backup copy of the files on the drive to

be formatted.

Use the Low-Level Format program in the following situations:

v When you are installing software that requires a low-level format. v When you get recurring messages from the test programs directing you to run

the Low-Level Format program on the hard disk.

v As a last resort before replacing a hard disk drive.

Preparing the hard disk drive for use

When the Low-Level Format program is finished, restore to the hard disk all the files that you previously backed up.

1. Partition the remainder of the hard disk for the operating system. (The commands vary with the operating system. Refer to the operating system manual for instructions.)

2. Format the hard disk using the operating system. (The commands vary with the operating system. Refer to the operating system manual for instructions.)

3. Install the operating system.

You are now ready to restore the files.
