Hard Disk: When Data is Unrecoverable

On an event of loosing your data there are cases where your data can happen to be unrecoverable:

Usually a disk with errors will issue warning on the screen that the disk is not formatted. Formatting the disk wipes out all the information stored in the disk. If you happen to install any application or copy files on the disk, the original data call it level one, will not be in a position to be recovered. This is why it is very important that, on noticing you have lost your data avoid connecting to internet to avoid automatic updates from writing on the disk.

Mishandling of the disk can lead to affecting the recovery process. Dropping or banging the disk can lead to breakages as the materials used to make the disk are fragile and can brake easily. This can lead to complete loss of data from broken platters and scratches. Those parts of the disk that may not accessible would be flagged as unrecoverable zones.
As more information and content on data recovery increases on the web, many are performing recovery of information from their drives on their own. Recovering data is a very sensitive task and there is only one chance, either you loss the data or you recover the data.

Having a non competent technician can lead to a massive loss of data that would lead to greater loss.

Using uncertified software from various websites can lead to altering the structure of your data. This can change the construction of the original data. Any change can result to damaging files or even corrupting the whole file system. This can lead to some parts or the whole data irrecoverable.
