Why hard drive fail. Part two.

Earlier it was mentioned that excessive heat will  cause hard drive failure.  Closely related to that is dust.  Not simply the presence of dust on the hard drive. Ddust build up inside a laptop computer interferes with airflow.  A laptop computer requires occasional maintenance using a can of compressed air to remove dust build up from the air vents.
It should be obvious that dropping a laptop computer will cause serious harm.  That applies to the hard drive inside a laptop.  Although modern designs have improved, the hard drive can be damaged by severe shock from a fall.  This is where prevention is better than a cure.
Most laptop owners would not remove their hard drive is on regular basis.  But when they do, bad handling could also shortened the life of the hard drive. .  Nevertheless, occasionally a laptop owner of will have to remove the hard drive for  inspected and put it back in.  Just be careful and do not squeeze or push on the top and bottom surfaces of the hard drive assembly.  Instead, holder by the edges.
This discussion has been aimed primarily at hard drives in laptop’s.  With desktop Computers  some other issues would appear to bring on hard drive failure.  Most often this is when the owner it tries to change the hard drive from one computer to another.  More information on this in another post next week.

How to get Good Cheep Movies.

With the advance of movie downloading over the Internet, the cost of watching movies has come down quite a bit.  With the possible exception of what should pay at a local theater to see any new movie.
It is now possible to watch the movies on your computer for less than a dollar apiece. Previously, this was thought to be either a impossible or outright illegal.  Times have changed.
As you likely know, NETFLIX is now offering subscriptions for 8 dollars a month in the United States.  Although the selection is somewhat limited, they do have a very wide range of offerings, including some movies that  hit the box office only a few months ago.  If you and your family were to watch four movies a week or about 16 movies in a month, the cost of each movie would be about 50 cents.  And of course, you can watch the movie over again for no additional charge.  But there is no easy way for doing a direct downloads of NETFLIX videos and saving them on y0ur HDD..
The possible  alternative to the NETFLIX on demand service are other web sites that will allow you full high-quality downloads of recent box office movies. You may take up to two hours to to download a moving that only plays for 90 minutes. Yet once you did that, the movie is on your computer in a compressed format and you can watch at anytime you want day and night even if the Internet connection is poor.
So how can this be legal?  To tell the truth, I don’t know.  For more information,  go to Google or Bing or or Yahoo and put the following phrase in the search bar: “How to legally download good movies cheap.” .  You will be surprised by the answers found.
So what will NETFLIX do about this? Tat will be in later post here.

Better Security -Coming Soon.

Better Security -Coming Soon.
There was a time not too long ago when people did not have to worry about viruses attacking their personal computer.  So there will be a time when again will not worry about that sort of thing.  But that is in the future.  Is good to believe in the future, but we have to live every day one day at a time.  So how can you improve your computer security now?

This is the first of a series of short pieces on computer security.  The obvious thing is to select a good antivirus program, and the future article on give you some tips on which ones seem to be the best.
But for today, hears the tip that every new computer users should know.  Be very careful about your e-mail.  More often than you might think, computer viruses come through e-mail .To help cut down on the possibility of a virus being in your e-mail, put a limit on how many friends of yours received your personal e-mail.  In fact, you may wish to have to e-mail accounts.  One for business use and another for strictly personal use.  Also, make an agreement with your friends cannot share of e-mail addresses with other people without your permission.  Surprisingly, many people inadvertently do this by building mailing lists and sending jokes and cartoons to their mailing list.  The problem with that is that every name in the list will show up on every e-mail that is sent out.  If you look on the outgoing message form you will see there is a place for carbon copy and blind carbon copy.  The recommendation is tell your friends to all issues the BCC, blind carbon copy, for messages they go out to a large group of recipients.  Otherwise, too many people are going to see the names of many people they don’t know and that may not be a good idea.
That’s today’s security tip..  More next week.

Why do hard drives fail?

Perhaps this is happening to you.  You have a portable computer and you take it on a trip with you and it stops working. When you get back home you find that the hard disk drive has failed and needs to be replaced..

The most notorious type of hard drive failure is called a head crash.  This is whether a read/write head comes down hard on the disk and does damage to itself and the disk.  In such a situation you’d have to send a hard drive to any special service agency to re cover most of the drive data.
However, many hard drive failure are nut  that drastic.
This is the first part of the series a short articles about hard disk drive failure and what you can do about it.
Today’s tip is about heat.  More often then you might expect, it  is heat that shortens the life of the hard drive. Give  attention to how hot your left top computer gets.  Keep it cool, and the hard drive will last much longer.  That should be rather obvious, yet  sometimes people forget that hard disk drives do have very strict temperature limits.  And yes, don’t let them freeze either.  Freezing temperature is very damaging to a hard disk drive.

Thia’s all for today. Comments welcome.
