On the last seminar SCITE (Student Conference 2008), I was able to know what are some of the latest technology and threats today. Some of what I’ve learn is about the Moore’s Law (Gordon Moore). The co-founder of Intel predicted 1965 the traneist orsdensity.EMAC- Feb.14, 1946, 1768 vacuum tubes. And also about Cyber Crimes like the Viruses, Worms, Trojans, Spam, Dialers, Spyware, Adware, Hacking Attacks, Phising and Keylogger. And also the entertaining speech of Mr.Pocholo Gonzales, about the voices in animation. But one thing that I’ve notice and dismay is their sound system and the food was not quite good. And I hope that their guest speakers would be as entertaining and alive like Mr.Pocholo to avoid boredom during their speech.

--> PATA(IDE/EIDE) 40-conductor data cable - Originally, the IDE interface supported two devices on a single controller. With the introduction of Extended IDE, two controllers capable of supporting two devices each were introduced. 40-pin connectors are used on 40-conductor ribbon cable. The cable has two connectors for the drives and a third for the controller.
--> PATA (EIDE) 80-conductor cable - As the data rates available over the EIDE interface increased, the chances of corruption of the data being transmitted increased. the use of 80-conductor cable was introduced for devices transmitting at 33.3MBps and over, allowing for a more reliable balanced data transmission. The connectors are still of the 40-pin variety.
You have completed this lab. The computer case should contain the motherboard, the CPU, and any cooling devices. Do not remove any additional components from case.

If you have an antistatic mat, place it on the work surface and put the computer case on top of it. Ground the antistatic mat to an unpainted, metal part of the case.
Step 4
Locate the hard drive. Carefully disconnect the power and data cable from the back of the hard drive.
Which type of data cable did you disconnect?
--> PATA,for hard drives use.
Step 5
Locate all of the screws that hold the hard drive in place. Use the proper size and type of screwdriver to remove the hard drive screws. Put all of these screws in one place and label them.
What type of screws secured the hard drive to the case?
--> Phillip head screws.
How many screws secured the hard drive to the case?
--> Two Phillip’s head screws
Is the hard drive connected to a mounting bracket? If so, what type of screws secure the hard drive to the mounting bracket?
--> No
CAUTION: Do NOT remove the screws for the hard drive enclosure.
Step 6
Gently remove the hard drive from the case. Look for a jumper reference chart on the hard drive. If there is a jumper installed on the hard drive, use the jumper reference chart to see if the hard drive is set for a Master, Slave, or Cable Select (CS) drive. Place the hard drive in an antistatic bag.
Step 7
Locate the floppy disk drive. Carefully disconnect the power and data cable.
Step 8
Locate and remove all of the screws that secure the floppy drive to the case. Put all of these screws in one place and label them.
Place the floppy drive in an antistatic bag.
How many screws secured the floppy drive to the case?
-->Two Phillips head screws.
Step 9
Locate the optical drive (CD-ROM, DVD, etc). Carefully disconnect the power and data cable from the optical drive. Remove the audio cable from the optical drive.
What kind of data cable did you disconnect?
--> Parallel ATA
Is there a jumper on the optical drive? What is the jumper setting?
--> None…
Step 10
Locate and remove all of the screws that secure the optical drive to the case. Put all of these screws in one place and label them. Place the optical drive in an antistatic bag.
How many screws secured the optical drive to the case?
--> Two Phillips head screws.
Step 11
Locate the power supply. Find the power connection(s) to the motherboard.
Gently remove the power connection(s) from the motherboard. How many pins are there in the motherboard connector?
--> 20-pin connector with a 24-pin socket motherboard.
Does the power supply provide power to a CPU fan or case fan? If so, disconnect the power cable.
--> Yes
Does the power supply provide auxiliary power to the video card? If so, disconnect the power cable.
--> Yes
Step 12
Locate and remove all of the screws that secure the power supply to the case. Put all of these screws in one place and label them.
How many screws secure the power supply to the case?
--> 4 Phillips Screw heads
Carefully remove the power supply from the case. Place the power supply with the other computer components.
Step 13
Locate any adapter cards that are installed in the computer, such as a video, NIC, or modem
adapter.
Locate and remove the screw that secures the adapter card to the case. Put the adapter card screws in one place and label them.
Carefully remove the adapter card from the slot. Be sure to hold the adapter card by the mounting bracket or by the edges. Place the adapter card in an antistatic bag. Repeat this process for all of the adapter cards.
List the adapter cards and the slot types below.
Adapter Card Slot Type
Network Interface Card PCI
Sound/AudioCard PCI
Video/Graphics Card AGP
Step 14
Locate the memory modules on the motherboard.
What type of memory modules are installed on the motherboard?
Dual inline memory module(DIMM), Synchronous Dynamic Dual Data Rate 1(SD-DDR1)
How many memory modules are installed on the motherboard?
--> 1
Remove the memory modules from the motherboard. Be sure to release any locking tabs that may be securing the memory module. Hold the memory module by the edges and gently lift out of the slot. Put the memory modules in an antistatic bag.
Step 15
Remove all data cables from the motherboard. Make sure to note the connection location of any cable you disconnect.
What types of cables were disconnected?
--> Floppy disk drive (FDD) data cable – Data cable has up to two 34-pin drive connectors and one 34-pin connector for the drive controller.
--> PATA(IDE/EIDE) 40-conductor data cable - Originally, the IDE interface supported two devices on a single controller. With the introduction of Extended IDE, two controllers capable of supporting two devices each were introduced. 40-pin connectors are used on 40-conductor ribbon cable. The cable has two connectors for the drives and a third for the controller.
--> PATA (EIDE) 80-conductor cable - As the data rates available over the EIDE interface increased, the chances of corruption of the data being transmitted increased. the use of 80-conductor cable was introduced for devices transmitting at 33.3MBps and over, allowing for a more reliable balanced data transmission. The connectors are still of the 40-pin variety.
You have completed this lab. The computer case should contain the motherboard, the CPU, and any cooling devices. Do not remove any additional components from case.

2.2.2 : Diagnostic Software
1. Based on your research, list at least two different hard drive manufacturers.
Fujitsu,
Seagate
2. Based on your research, choose a hard drive manufacturer. Does this manufacturer offer hard drive diagnostic software to go with their products? If so, list the name and the features of the diagnostic software
Manufacturer:
Samsung
Software Name:
ES-Tool (The Drive Diagnostic Utility) v2.11
File Name:
ES-tool (for FDD).exe
File Size:
Size : 437 KB
Version:
v2.11
Publish Date:
03.20.2008)
Description:
ES Tool (The Drive Diagnostic Utility) is made with the aim of testing a Samsung hard disk drive while it is installed inside a PC, regardless of the status of user's operating system. In fact of the drives returned to Samsung, a large percentage are NTF("No Trouble Found") after testing. So it is strongly recommended to test the drive if it is truly defective by a few fundamental troubleshooting of ES Tool first, to avoid user's unnecessary effort and inconvenience of replacing a good drive.
