In any case, if the hard drive or SSD is physically destroyed, there will be at least parts of the information that will be unrecoverable and will have been lost forever and, in fact, it is much more likely to be able to recover information from a hard drive. Mechanically destroyed than an SSD, since as you know the information is stored on the NAND chips instead of physically (with physical peaks and valleys representing the ones and zeros) on the platters of a disk.
The hard drives found in contemporary computers hold a significant quantity of information, encompassing the operating system, applications, and user data, which is usually the target of recovery attempts. Furthermore, the drives contain a backup storage for virtual memory and operating system Meta information, such as directories, file attributes, and mapping tables, resulting in a low probability of successfully retrieving the desired data.
The most common ways to leave data unrecoverable are as follows:
- Physical destruction of the device, such as sanding the platters or sticking a screwdriver into the NAND chips of an SSD.
- Demagnetize a mechanical hard drive to randomize the magnetic domains (bring it closer to powerful magnets, essentially).
- To permanently erase data from the universe, the easiest and most efficient method is to overwrite all the information on the drive multiple times. By formatting the disks and filling them completely again, any previous data will no longer exist as it won’t physically fit in. Therefore, if you erase your storage unit once more, the data will be unrecoverable. Remember, this is the ultimate solution to ensure complete deletion. Now you’re aware of what needs to be done if you truly want to delete something.
- In other cases, data from the hard drive or SSD can almost always be recovered using the methods that we have listed before in this article.
- It is common for storage devices, whether internal or external hard drives, to be affected by various types of errors. In order not to lose the information stored inside, it is essential to have a team of professionals who know how to proceed to fix the device, if possible, or at least be able to recover all the data inside when we cannot access it.
