The risk of losing our files due to damage to the media used or, worse, a virus caught while browsing can be avoided by using good antivirus and making continuous backups or using a cloud.
But how many are really that diligent? Very few. But it must be added that antivirus and backup are not always the optimal solution to avoid data loss.
How to recover hard disk data
Although there are online guides on data recovery from damaged media, unless you are a computer expert it is good to contact specialized laboratories, companies with advanced technologies able to analyze the storage medium and present a complete diagnosis to the customer.
Data can be recovered from media such as:
hard disk
Tablet
memory card
CD
DVD
mobile phones and smartphones
Raid systems
Server
Nas
USB sticks
SSD
But first of all a diagnosis must be made, to understand how many and which files can be recovered.
The cases in which a loss of stored data occurs are many and due to various causes, which is why only a laboratory of experts will be able to guarantee the feasibility of recovery to the customer. But above all, he will have the right technology and recovery techniques suitable for the case in question.
The causes of data loss
A medium such as a hard drive can prevent us from accessing our files for several reasons:
physical damage, for example due to a falling computer or impact
electronic damage, due to overvoltage, power surges, power failure
contact with water or other liquids
direct contact with heat sources such as fire
accidental deletion of files
formatting the hard disk
But there are also check for corrupted or overwritten files.
The average user in some cases may know the cause of data loss (especially if their media has fallen on the ground or in water or if they have caught a virus, etc.), but in others they will not understand why they cannot access their files. .
Only a data recovery expert will first be able to detect the problem and then work out the right strategy for recovering the data.
