Computer crashes can happen in an instant, taking hundreds of gigabytes of data with them into the digital ether. These crashes can be caused by a power outage or even a battery simply losing its charge. Data recovery after such an event can be a headache for the average computer user, and even experts in the field of computer repair fear a crash. There is no one reason why data recovery can be a difficult undertaking, as there are several factors that affect any crash and what comes after.
What’s So Difficult About Data Recovery?
Computer data can be surprisingly delicate. Hard drives are fickle, and can be corrupted with almost no notice over a period of time. Modern devices are designed with more safeguards in mind, but to the average consumer who doesn’t keep up with the latest in computer advances and data storage, a computer crash can wipe out years of stored data. One of the greatest threats to data recovery is a lack of secondary storage. A backup hard drive or cloud storage is a great way to preserve data in the event of a computer crash, but many people don’t take advantage of these options. Without a backup, it can be extremely difficult to restore lost data.
Another problem plaguing data recovery is simple human error. When the average person is using a computer, a common complaint is that the computer “runs slowly.” An individual may attempt to clear space on the hard drive, freeing up processing power so that the device runs more smoothly and quickly. In doing so, valuable data can be erased completely, without the user knowing for sure what is lost forever and what is recoverable. When a data recovery expert is attempting to salvage lost data, they can encounter difficulty with situations like this; the computer owner isn’t exactly sure what was deleted and when, only that they cleared up a bunch of space on their cluttered hard drive.
Since each situation is unique to a device, computer crashes don’t have a catch-all solution for total data recovery. Everything from actual physical damage to a computer to more nebulous situations like hardware failure contribute to data loss, and a data recovery expert must keep in mind every possible situation so they can do what they can to recover as must lost data as possible, while keeping in mind that complete recovery is unlikely and, in some cases, impossible.
