Step By step ways on how to Troubleshoot the IDE on a computer


Step By step ways on how to Troubleshoot the IDE on a computer

Here come today with new tip on technology branch (software/hardware part) which is how to troubleshoot the ide of a computer system, BEFOR WE BEING YOU MAY ALSO LIKE TO CHECK ON How to know the Measurements of electrical quantities on a computer system.


OBJECTIVES
 1. Explore ide cable configuration
 2. Explore ide device master/slave jumper setting
RESOURCES
1. Pc desktop/tower computer system
 2 faulted hardware component- faulted ide cable

DISCUSSION
 the setting of the various drives comprises the master/slave format. The master/slave setting will normally master if the unit is the primary or the only hdd in the system. This is called the default setting, that is, from the factory. The cd-rom will be the slave unit by default. Hard drives are very sensitive to physical damage. If a hard drive drops from your hand from about 4 inches above the table, there is no guarantee that it will still work. The hard drive’s head will crash on the disk and will create bad or unreadable sectors, especially if sector 0 is involved. Then the drive table and information will be lost and drive will be unusable.
Procedure
1. Standard configuration week 13
(a) refer to the hdd documentation to determine the drive select or master/slave jumper setting
(b) obtain the drive’s parameter information from the driver or information booklet and record it in table 3-1
 (c) check to make sure that all the screws are secured in the drive and that it is not loosed.


hard drive mounting screws are secure

note: ide drives use a signal wide signal cable’s you know from lab 1, the signal cable
must be aligned correctly at both the drive and controller ends. The strip must be aligned
with #1 pin at both ends. All new cables are keyed to prevent backwards installation. (d) verify the connection of the signals cable to the hdd, the cd-rom, and the hdd controller on the mother board .
(i) turn on the computer.
(j) press delete to enter cmos when prompted.
(k) go into standard cmos setup.
Pg. 84
(l) the primary master should be the hdd. Press enter to verify it is set to “auto”.
(m)make sure all other hard drives are set up for auto deletion, and be sure the “access mode” is also set to auto. Change the settings if they are not set to auto.
(n) press esc to view the main menu.

(o) press f10, y, and enter to save and exit cmos.
(p) verify that the computer boots up to the microsoft windows xp.
(q) turn the computer off.
 2. MASTER IDE DEVICES
 (a) connect the cd-rom and hard disk drive to the same ribbon cable (the original hdd cable). Verify that the hard disk drive is set to master on the drive select jumper. Verify the cd-rom to the master setting also on the drive select jumper.
(b) turn the computer on.
(c) write the result in table 3-2.
 (d) turn the computer off

 3. MASTER CD-ROM, SLAVE HDD

(a) change the jumper on the hard disk drive on the slave settings.
(b) turn the computer on.
(c) press delete to enter cmos.
(d) enter standard cmos setup.

(e) note the differences in table 3-3.
(f) press f10, y, and enter to save and exit cmos.
(g) write the results in table 3-4.
(h) turn off the computer.

7.MASTER HDD, SLAVE CD-ROM

(a) change the cd-rom drive select jumper back to the slave position.
(b) change the hard drive jumper back to the master position.
(c) turn the computer on.
 (d) record the result in table 3-5.
 (e) turn the computer off. As you can see, it does not matter which drive is set to master as long as there is one drive set to master .however , if the slave device had been a hard drive instead of a cd-rom the computer would have tried to boot from the ide-0 every time. If it was not bootable you would have received an error message.

8. INCORRECT IDE CABLE ORIENTATION
 (a) unplug the 80-pin cable from the cd-rom and hdd.
 (b) plug the 40-wire cd-rom cable into the hdd.
(c) turn the computer on.
 (d) write the results in table 3-6.
 (e) turn the computer off.
Return all cables and jumper to their original configuration.

How to know the Measurements of electrical quantities on a computer system.

Hello my  follower alitechzy(ALITEch) is here again with another responsible post on technology aspect  again (Measurement of electrical quantities on a computer system).
Here are some briefly explanation or briefly explained step’s on how to Measure a electrical quantities on a computer system.
So let sit tait ,sit well and read/study the step gradually carefully, hope we should be able to achieve from our(alitech) article .
NOT TO TALK MUCH SO LET GO strength to the point but before we go you may Also like to check out:HOW TO ASSEMBLING AND DISASSEMBLING A COMPUTER SYSTEM



OBJECTIVES
1. Measure Resistance on a speaker
 2. Measure Voltage from a power supply

RESOURCES
1. PC desktop/tower Computer System
 2. Digital Multimeter with Lead
3. A good fuse 4. A bad fuse

DISCUSSION
Here you will measure various electrical quantities on a computer. The Multimeter can be used to measure resistance, current and potential across a circuit Procedure
4. Resistance on a speaker
 (f) Open the inside of the PC
 (g) Rotate the Multimeter dial to 200 ohms
(h) Hold the Red lead on the exposed end of the Red wire that connect the systems’ speaker

(i) Hold the Black lead on the exposed end of the Black wire that connect the systems’ speaker
(j) Record the reading of the meter in Table 2-1 5.5. Voltage (f) Turn on the power of the PC
(g) Look for the 20-pin ATX power connector that in plugged into the motherboard. It should look like the location 1 in
. (h) Rotate the Multimeter dial to 20 Vdc
(i)                  Firmly secure the black connector to the Multimeter into a black connector of the 4-pin internal drive power connector as in location 2
(j) Insert the Red Multimeter connector into each pin on the ATX connector and record their various voltages in Table 2-2
NOTE: the pin number is small and may be labeled on the back wire of the connector.
The yellow wire should be one
(f) Check the voltage at each pin of the 4-pin internal drive power connector and record the . Values in Tables 2-3
(e) Turn off the PC
(f) Replace the side panel
6. Fuses
(k) Obtain the two fuses; one good and one bad
(l) Rotate the Multimeter dial to 200 ohms
(m)Touch the two leads together and record the Multimeter reading in Table 2-4. You now establishing a datum or zero point of no resistance
(n) Without touching the leads together, record the Multimeter reading in Table 2-5
(o) Place one lead on one and of the good fuse.
(p) Place the other lead on the other end of the good fuse. Make sure that your finger or the leads are not touching each other
NOTE: The only path for electricity to flow is through the fuse
(q) Record the Multimeter reading in Table 2-6
(r) Place one lead on one and of the bad fuse
(s) Place the other lead on the other end of the bad fuse. Make sure that your finger or the leads are not touching each other

NOTE
: The only path for electricity to flow is through the fuse
(t) Record the Multimeter reading in Table 2-7
