Why People Mistakenly Think Their Laptop Hard Drive is Safe From Failure

One of the things that may lead to massive data loss is ignorance, in our case it is ignorance of the hard drive failing. Some of the thoughts that go through people's minds concerning this are:
Data has been backed up on a separate hard disk: It is an advisable practice to backup ones data, but the backup can also fail. What if the backup is out-dated? When was the last time the backup was tested? How often is the backup done? These are some of the questions that should be considered when one thinks that backups can be totally trusted. It is also possible for backups to be destroyed together with the originals in cases of natural disasters like floods, fires, earthquakes etc. Therefore, your backup is not 100% safe.
Restricted surfing on the internet therefore, less chances of infection by viruses: It could actually be possible that one does not visit the so called "questionable" sites on the internet but that is not the only way that viruses infect the computer. Viruses can be spread through the portable storage media such as DVDs, CDs and USB flash disks. Also, with the emergence of file attachments, e-mail, instant messaging and other things shared by employees and friends, the risk of accidentally infecting ones hard drive increases and thus, no can ever be 100% careful.
Brand new hard drive: How many times have you bought a new piece of equipment such as a TV, clock, DVD player or any other electronic device and it has failed to work? I know it is rare but doesn't the hard disk fall into the same category? Just as in that rare occasion that a TV or a DVD player failed to work or worked for a while and stopped, a hard disk may work for a while and then fail
