Can Data Always Be Recovered?

Call The Computer Wizard • Sep 02, 2021

In many cases, lost data can be successfully recovered. However, in specific circumstances, recovery might not be possible. This is why it is crucial for any computer or smartphone user to perform regular data backup. Below, learn about a few instances when data can be retrieved, when it can't, and how to prevent nonrecovery incidents.

When Data Can Be Recovered

Data recovery is possible when a file and information about that file are stored in a different location. For instance, Windows® utilizes a file allocation table to monitor and manage the files on the hard drive. The table is essentially a directory, with the files stored in another place. 

If data has to be recovered, in most cases, it is this table that's not working as it should. The actual file to be recovered might still be on the hard drive, where it can be recovered if it is not damaged.

When Data Cannot Be Recovered

When there is serious damage to the hard drive media, data may be lost permanently. Hard drives retain data on platters that contain a layer of magnetic material. If this material is damaged or removed from the drive, data can be irretrievable.

Data can also be permanently lost if it is overwritten. Once a file is deleted, the hard drive will eventually start to overwrite the data, but the process is not instantaneous. The longer the computer is powered on, the higher the likelihood that lost data will be overwritten. If a data backup provider can get to the hard drive in a timely manner, data may be recoverable.

How to Prevent Nonrecovery Events

You can prevent nonrecovery events by implementing a strong data backup strategy. Cloud solutions are one popular and effective option. They allow you to store data on a remote database, separate from your device, where it can be retrieved as necessary.

You should also take steps to protect your hard drive from data loss. Be sure all programs and files you download come from a trusted source. Keep your operating system updated with the latest version to avoid glitches that can cause data loss. Regularly clean in and around the physical device to prevent debris buildup and performance issues. And, finally, perform routine data backup, saving files to multiple locations, preferably with encryption.
