| | | | Recovery Data Lost or Damaged
First of all you have to make a distinction between the many possible situations, or how data has been lost, in fact, when you take care of your computer you have to try to be as precise as possible on the causes: - Incorrectly erased sonostats
- Broken harddisk, your computer is no longer running, it crashes often, crashed with blue screen or does not start right
- A virus encrypted all my data (see article on Ransomware CryptoLocker)
At this point we will see the different situations |

| | | | | Erased erroneously
Do not despair the data could be recoverable, in fact even when they are permanently removed from the trash can still be "stored" on the hard disk, you simply can not be seen.
First, it does not take too much time to use, ie from the deletion onwards Windows recognizes those portions as free space so it can potentially overwrite all those files that are no longer visible, making them so unrecoverable; So less you have used the hard disk after the highest deletion is the probability of recovery.
Depending on the size of the memory and the number of files, the recovery process also varies for a long time.
Especially for small data (photos, documents, email ...) the probability of recovery if you intervene in a short time is quite high.

This is a much more delicate situation and obviously the causes can be varied as well as the solutions. First of all, a premise, after you turn on the computer you should hear the boot sound of the hard disk, if this does not happen you can already give a first diagnosis of any problems: - A continuous tick, for example, is indicative of a head problem, so we are talking about internal damage, in this case it is advisable to save the data as soon as possible and replace it, unless it is a new product makes no sense Try to fix it;
- A disc may not start due to a failure on the printed circuit board on the disk surface due to a power outage or wear, as the previous case replaces it is always the recommended choice, in this case it is undoubtedly more difficult to recover Given but not impossible;
- There is also a condition where not all the hard disk is damaged, but only part of its sectors is damaged, the recovery process in this case may no longer be possible for the damaged sectors, but only for the remainder .
Unfortunately, the more time passes, the more the disks are filled with data and they are worn out and there is not much that can be done to avoid it. A damaged or damaged disk is the most common cause of a computer that no longer starts and, as already described, a full or damaged disk is also the main reason why a computer, after a few years, becomes slower.
If the classic methods of data retention are always negative, it is necessary to send it as a last resort to a data recovery center that is equipped with a professional white room and can recover with a high percentage of data; However, this road may be very expensive, generally over 700 € |

| | | | | HOW TO PREVENT THE DATA LOSSES
The answer is simple: just take care of the data that we have more to make one or more copies on other media, we have more and more cloud services today, one of the benefits of the cloud is that the archived data is accessible by Any PC, just have an internet connection, so having a copy does not cost them anything.
Pay attention to the symptoms of our memory media when they start to generate errors when opening some files, take too long to show the content or they are not recognized (so the speech is also extended to memory media like usb pins) It is always better to take a look at who you want it to.
