Fixed disk advanced test (FDAT)

PC-Doctor???s (PCDR) Fixed-Disk Advanced Test module (FDAT) is a full-featured highly configurable fixed-disk test suite. The configurable capabilities of FDAT allow users to enable or disable specific tests, enable or disable testing features, control the test log detail, alter testing parameters, etc. FDAT will test for and report most commonly found errors on a fixed-disk drive and is able to test up to 128 SCSI and 4 IDE drives (up to 132 total drives). Drive information is gathered through FDAT???s enumeration of available devices and user specific configuration parameters located in the FDAT.INI. FDAT uses information supplied by these features to indicate specifically what devices are available for test, what tests are available for the device, device properties, etc. Modify the FDAT.INI file in PC Doctor for DOS to change testing parameters.

FDAT consists of the following subtests and features.

16 Hardware Maintenance Manual

Fixed-Disk Tests:

vSeek Tests - checks the physical operation of the drive head.

???Linear Seek

???Random Seek

???Min-Max Seek

???Butterfly Seek

vVerify Tests - checks the integrity of the data present on the media.

???Linear Verify

???Random Verify

vSurface Scan Tests - checks the drive media for defects.

???Surface Scan (Linear)

???Surface Scan (Aggressive) - this is disabled for normal customer use.

???Surface Scan (Random)

vSMART - checks the SMART functionality for drives that support SMART.

???Start SMART Self-Test

???Get SMART test results

Other Test Features:

vWrite-Splice Repair - detects and corrects Error Correction Code errors during Verify tests.

vAuto Spin Down - a gradual spin down of the drive platters to avoid damaging the media.

vManufacturer Log - an in-depth manufacturer supported log of errors on the drive.

Multitasking:

To allow simultaneous testing of multiple hard drives whenever possible, the FDAT module is written as a set of multitasking functions. Each drive under test can run the same test or run a different test at the same time. Each subtest is written to handle a single test pass and all test variables are kept track of in a structure unique for each drive. However, when testing IDE drives, FDAT will not perform simultaneous testing of IDE drives that are attached to the same IDE cable. For example, if FDAT is testing four IDE drives on a PC, it will perform simultaneous testing on drives 1 and 3 first (master drives), then perform tests on 2 and 4 (slave drives). FDAT will also perform simultaneous testing on a master and slave that are on separate IDE cables, but will not perform simultaneous tests on a master and slave on the same IDE cable. This generally increases the amount of time needed to test multiple IDE drives.

Another limitation of FDAT???S multitasking capability is the use of Ultra DMA (UDMA). Only one drive at a time can access the UDMA channel and the UDMA channel buffer must be kept high in order to maintain a speed advantage over other data transfer modes. In order to use the UDMA channel during testing, users must disable the multitasking feature.

Destructive vs non-destructive testing:

Most of the tests found in FDAT are non-destructive. This means that PCDR will preserve any data that is present on the tested media prior to beginning any destructive operations (i.e. write operations). However, users can run certain tests

Chapter 4. IBM Enhanced Diagnostics 17

in destructive mode (i.e. surface scan tests). Destructive tests will speed up testing because FDAT does not preserve the data on the media prior to the test beginning. Unlike non-destructive tests, any data present on the media prior to the test beginning is lost. FDAT allows for enabling or disabling destructive tests, as well as specifying a range of destructive and non-destructive sectors on the tested drive. This is done through the configuration of the FDAT.INI. If destructive and non-destructive ranges somehow overlap, then the overlapped area is considered non-destructive. For example, if users specify both destructive and non-destructive ranges as the same, then the entire drive is tested as non-destructive.

Quick and Full erase - hard drive

The Diagnostics program offers two hard drive format utilities:

vQuick Erase Hard Drive

vFull Erase Hard Drive

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

vDestroys the Master Boot Record (MBR) on the hard drive.

vDestroys all copies of the FAT Table on all partitions (both the master and backup).

vDestroys the partition table.

vProvides messages that warn the user that this is a non-recoverable process.

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

vPerforms all the steps in Quick Erase.

vProvides a DOS utility that writes random data to all sectors of the hard drive.

vProvide an estimate of time to completion along with a visual representation of completion status.

vProvides 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.

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.

vPress F3 to activate the log file.

vPress F3 again to save the file to diskette or F2 to print the file.

POST error codes

Each time you power-on the system, it performs a series of tests that check the operation of the system and some options. This series of tests is called the Power-On Self-Test, or POST. POST does the following operations.

vChecks some basic system-board operations

vChecks the memory operation

vStarts the video operation

vVerifies that the diskette drive is working

vVerifies that the hard disk drive is working

If the POST finishes without detecting any problems, a single beep sounds and the first screen of the operating system or application program appears.

Note:

Some computers default to come up quiet (no beep and no memory count and checkpoint code display) when no errors are detected by POST.

To enable beep and memory count and checkpoint code display when a successful POST occurs, do the following:

1.Select Start Options in the IBM Setup Utility program (see Chapter 5, ???IBM Setup Utility program,??? on page 19).

2.Set Power-On Self-Test to Enhanced.

If the POST detects a problem, an error message appears on the screen. A single problem can cause several error messages to appear. When you correct the cause of the first error message, the other error messages probably will not appear on the screen the next time you turn on the system.

Security features in this section include the following:

vPasswords

vVital Product Data

vAlert on LAN

Passwords

The following section provides information about computer hardware and software-related passwords.

vPower-on Password

vAdministrator Password

vOperating System Password

Power-on and Administrator passwords are set in the Setup Utility program. See Chapter 5, ???IBM Setup Utility program,??? on page 19 for information about running the Setup Utility.

Power-on password

A power-on password denies access to the computer by an unauthorized user when the computer is powered on. When a power-on password is active, the password prompt appears on the screen each time the computer is powered on. The computer starts after the proper password is entered.

Removing a power-on password

To service a computer with an active and unknown power-on password, power-off the computer and use the following procedure.

Note: On some models, this procedure will also remove the administrator password.

1.Unplug the power cord and remove the top cover.

2.Refer to ???Identifying parts on the system board (all machine types)??? on page 38 to find the Virtual clear CMOS/BIOS recovery jumper.

3.Move the recovery jumper from normal to ROM recovery.

4.Power-on the computer. The system senses the change in the position and erases the password.

5.Wait 30 seconds for beeps to sound, and then power down by holding the power button for 10 seconds.

6.Return the jumper to normal position.

7.Reset the date and time and remind the user to enter a new password when service is complete.

Administrator password

The administrator password is used to restrict access to the IBM Setup Utility program. If the administrator password is activated, and you do not enter the administrator password, the configuration can be viewed but not changed.

Note:

Your computer has Enhanced Security Mode. If Enhanced Security mode is enabled and there is no password set, the computer will act as if Enhanced Security is disabled.

If Enhanced Security is Enabled and an administrator password is set, the administrator password must be entered to use the computer. If the administrator password is lost or forgotten, the system board in the computer must be replaced in order to regain access to the IBM Setup Utility program.

Administrator password control

The Administrator password is set in the IBM Setup Utility program. Refer to

Chapter 5, ???IBM Setup Utility program,??? on page 19.

Operating system password

An operating system password is very similar to a power-on password and denies access to the computer by an unauthorized user when the password is activated. The computer is unusable until the password is entered and recognized by the computer.

Vital product data

Each computer has a unique Vital Product Data (VPD) code stored in the nonvolatile memory on the system board. After you replace the system board, the VPD must be updated. To update the VPD, see ???Flash update procedures??? on page 113.

Chapter 10. Related service information

Note: The service procedures are designed to help you isolate problems. They are written with the assumption that you have model-specific training on all computers, or that are familiar with the computers, functions, terminology, and service information provided in this manual.

Safety information

The following section contains the safety information that you need to be familiar with before servicing an IBM computer.

General safety

Follow these rules to ensure general safety:

vObserve good housekeeping in the area of the machines during and after maintenance.

vWhen lifting any heavy object:

1.Ensure you can stand safely without slipping.

2.Distribute the weight of the object equally between your feet.

3.Use a slow lifting force. Never move suddenly or twist when you attempt to lift.

4.Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any objects that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

vDo not perform any action that causes hazards to the customer, or that makes the equipment unsafe.

vBefore you start the machine, ensure that other service representatives and the customer???s personnel are not in a hazardous position.

vPlace removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine.

vKeep your tool case away from walk areas so that other people will not trip over it.

vDo not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.

vInsert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately 8 centimeters (3 inches) from the end.

vDo not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.

Remember: Metal objects are good electrical conductors.

vWear safety glasses when you are: hammering, drilling soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

vAfter service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.

vReinstall all covers correctly before returning the machine to the customer.

Electrical safety

CAUTION:

Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunication systems, networks, and modems before you open the server/workstation covers, unless instructed otherwise in the installation and configuration procedures.

Observe the following rules when working on electrical equipment.

Important: Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents.

Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.

vFind the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.

vDo not work alone under hazardous conditions or near equipment that has hazardous voltages.

vDisconnect all power before:

???Performing a mechanical inspection

???Working near power supplies

???Removing or installing main units

vBefore you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

vIf you need to work on a machine that has exposed electrical circuits, observe the following precautions:

???Ensure that another person, familiar with the power-off controls, is near you.

Remember: Another person must be there to switch off the power, if necessary.

???Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back.

Remember: There must be a complete circuit to cause electrical shock. By observing the above rule, you may prevent a current from passing through your body.

???When using testers, set the controls correctly and use the approved probe leads and accessories for that tester.

???Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

248 Hardware Maintenance Manual

vRegularly inspect and maintain your electrical hand tools for safe operational condition.

vDo not use worn or broken tools and testers.

vNever assume that power has been disconnected from a circuit. First, check that it has been powered-off.

vAlways look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.

vDo not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage.

vDo not service the following parts with the power on when they are removed from their normal operating places in a machine:

???Power supply units

???Pumps

???Blowers and fans

???Motor generators

and similar units. (This practice ensures correct grounding of the units.)

vIf an electrical accident occurs:

???Use caution; do not become a victim yourself.

???Switch off power.

???Send another person to get medical aid.

Safety inspection guide

The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

vElectrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock).

vExplosive hazards, such as a damaged CRT face or bulging capacitor

vMechanical hazards, such as loose or missing hardware

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

1.Check exterior covers for damage (loose, broken, or sharp edges).

2.Power-off the computer. Disconnect the power cord.

3.Check the power cord for:

Chapter 10. Related service information 249

a.A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground.

b.The power cord should be the appropriate type as specified in the parts listings.

c.Insulation must not be frayed or worn.

4.Remove the cover.

5.Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

6.Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

7.Check for worn, frayed, or pinched cables.

8.Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling electrostatic discharge-sensitive devices

Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.

Notes:

1.Use product-specific ESD procedures when they exceed the requirements noted here.

2.Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts:

vKeep the parts in protective packages until they are inserted into the product.

vAvoid contact with other people.

vWear a grounded wrist strap against your skin to eliminate static on your body.

vPrevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.

vUse the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.

vSelect a grounding system, such as those listed below, to provide protection that meets the specific service requirement.

Note: The use of a grounding system is desirable but not required to protect against ESD damage.

???Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.

???Use an ESD common ground or reference point when working on a double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.

???Use the round ground-prong of the ac plug on ac-operated computers.
