A large number of computers sold are laptop computers. They are light and portable. Modern laptops contain very large hard disks at the time of writing this article 500Gb are often seen here for data recovery.
One of the most common problems we see are drives where the heads have crashed. The main cause is actually part of the design of the computer - remember the bit where I said 'they are light and portable'? It is easy to put the computer on your lap, then when you need to get up, lift the computer up and put it to one side. This movement can cause a head crash especially if the heads are reading or writing at the time. Most manuals that we have seen recommend putting the computer on a firm surface like a desk or a table and in fact NOT putting it on your lap - strange that they are called 'laptops' when it is not recommended to use them as such.
Some manufacturers have developed hardware that detects when the computer is being moved and pulls the heads to a safe place to help avoid any damage. This is a definite benefit and can help to avoid the cost of expensive data recovery.
Laptop hard disks also suffer from the usual problems that hard disk suffer however users seem to be less likely to back up data on a laptop. Or if they do it may be done at irregular intervals or at one location but the computer is mainly used at another. When the user returns to the first location the data is synchronised with the backup server. It is when the failure happens between backups that the requirement for data recovery becomes important.
