I don’t like the sound of my hard drive

The Computer System
Targetted students: A+ Trained Technicians

Case study: “Where is the sound coming from?”
If your answer  is ” hard drive”  then you are good to go. But if your answer is  “computer” then. . .its ok.

Frankly, I preferred the hard drive answer. Why? Go and research! I have no time to explain. A+ Trained Technicians should know the concept, if not then review the basic.

Reinforcement question:
What part of the computer is making the noise and why? Think like a technician.

Sample answer: The hard drive is making the noise especially when retrieving data/files/information  needed at the moment. But when the data are already cached, the hard drive is typically quite. The 4 gigs RAM (4, 000 megabytes) should be attributed after the facts.

Recommendation: Time to backup all important files.

What type of back up do you recommend?

Hands on exercise: Build a computer with the additional specifications to be delivered in 5 hours.

Specifications: Basic component – RAM 4 gigs, HDD 500 Gigs, AMD 64
Windows Vista Ultimate Edition
Graphics by NVIDIA
CompactFlash I/II/MD
MS/PRO/Dou/Pro Duo
1 Expansion Bay
1 Pocket Media Drive Bay

    Computer technicians also need to deal with people who’s communication and technical skills may not be all that good.

    For example, I had to help someone over the phone who didn’t know what OS they were using.
    They knew the computer was HP, but nothing more than that.

    First step when you hear the noise would be to turn off the computer. Then head off to the local computer store and get an external USB drive (something with good capacity) and a new hard drive. This is an expensive step, but it depends on how much your data is valuable to you.

    Turn on the computer, connect the USB drive and let it recognize (don’t run any more apps) and then dump everything in My Documents and the desktop into it.

    Once the dump is complete, shutdown.
    Disconnect the defective drive and reconnect the newly bought one.
    Disconnect from the internet (if wired) or disable your wi-fi. This is a security measure.

    Reinstall the OS and drivers and reconnect to the Internet. Download all patches and updates and then install a good Antivirus (I recommend Avast) and install Ad-Aware.

    Now the backup data can be copied back to the computer from the USB drive.

    Of course the USB drive step can be avoided if you keep weekly or monthly backups.

    I like to sort my work in folders by years and months. Every week or so, I dump everything I’ve recently worked on into a DVD-R.

    If I’m going to work on something from a few months back, I copy it into a new folder for the current month leaving the old copy intact.
    This way, I avoid duplicating them in the backups and also have a fairly good versioning system for the original copy.

      Thanks for the tips. Hope people will understand that owning a computer is a big responsibility. You cannot just buy it and forget everything until problems arise.
