Hello Friends, as some of you know from my Introductory Post one of the works I do for a living is repairing computers.

This week something very curious happened to me and I want to share with you, so in case that you have this hardware installed on your computers take the necessary steps to put your important information safe.

First a little definition.

Planned obsolescence or built-in obsolescence in industrial design and economics is a policy of planning or designing a product with an artificially limited useful life, so it will become obsolete (that is, unfashionable or no longer functional) after a certain period of time. The rationale behind the strategy is to generate long-term sales volume by reducing the time between repeat purchases (referred to as "shortening the replacement cycle"). Source Wikipedia

This week came to my repairer shop 4 computers with the same symptoms, problems booting the OS and the famous blue screen of death in Windows, what I did was try to do a clean install on the hard drive to see if simply it was an error of the OS, but as always first I try to backup the information of my clients with a very useful tool called Hirens Boot is a versatile LiveCD for backup and other types of repairs, the case was there was no way to reinstall the operating system or backup any information because the hard drive had serious trouble reading or writing information, it just got stuck and did nothing.

Yesterday while talking to my wife about some of the repairs that were made in the week, I searched the bad hard disks that we changed and I notice that these 4 computers had installed the same model of Hard Disk and that over a period of 1 week all had damaged in the same way.

Here is the model of hard drive so that in case you have installed on your computers, make sure you backup your important information in some other drive, as the saying goes "One cautious man worth by two" I don´t think that these 4 Hard Disks that are the same model and year of manufacture have been damaged by coincidence, in fact I think a great example of what we call Planned obsolescence.
