How to Deal with a Corrupted Hard Drive

How to Deal with a Corrupted Hard Drive

In this post, we will discuss how to deal with a corrupted hard drive, a common problem that affects hard drives and can result in the loss of important data.

We will cover the essential steps to diagnose problems with a corrupted hard drive and take the best actions to avoid losing information.

The first step is to identify a corrupted hard drive.

Symptoms of a Corrupted Hard Drive

Typically, a corrupted hard drive presents signs such as reading errors, system slowdowns, and frequent crashes. Pay attention to equipment crashes, which may signal a hard drive failure and should not be ignored. It is common for a hard drive to show signs of failure before stopping completely, and system slowdowns and crashes are the most common symptoms.

The sooner you identify these symptoms, the greater the chances of data recovery, as an early failure diagnosis can prevent further damage to the hard drive.

Diagnosis of the problem

There are tools that monitor the health of the HD and can alert you when a problem arises.

We have already shown tools that monitor S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) of the HDD and can be a great failure prevention option.

Steps to Diagnose a Corrupted Hard Drive:

• Use specific diagnostic tools such as CrystalDiskInfo or HDTune.

• Check the S.M.A.R.T. to identify possible problems.

• Perform file system integrity checks, only if there is no physical damage to the HDD.

Important: Before carrying out any procedure on the HDD, make sure you have an up-to-date backup of your data to avoid additional losses. If you do not have a data backup, stop immediately and seek professional help.

Problem resolution

There are situations where the HDD becomes corrupted and loses access to data due to some logical problem. A power outage, for example, can lead to this type of problem, and file system integrity checking tools can resolve the situation.

The big question is whether the problems are related to some type of physical damage to the HDD, such as damaged sectors or bad sectors.

Scanning programs may fail and data recovery software may crash, which can lead to a worse situation.

The best course of action if you suspect that the HDD has physical damage is to turn off the equipment, no longer turn on the HDD and seek professional help.

Preventing Future Corruption

To avoid hard drive corruption in the future:

• Keep your operating system and software always up to date.

• Avoid abrupt system shutdowns.

Use uninterruptible power supplies (UPS) to protect against power outages, which can even lead to more serious situations of physical damage to the HDD, such as burning the electronic circuit on the logic board, damage to the reading heads or magnetic media.

Data recovery

Using Data Recovery Software

There are several data recovery programs that can be used to try to recover files from a corrupted hard drive, such as Recuva and TestDisk.

Steps to Recovery:

• Install the data recovery software on a different disk than the one that is corrupted.

• Follow the software's instructions to scan and recover files.

Pay attention to the risks involved in this stage!

Recording information (installation of data recovery software, for example) or the results of scanning the data recovery software on the HD that is intended to recover the data is a classic mistake and ignored by many. This may result in the permanent loss of data, as the information you hope to recover will be overwritten.

The simple fact of using the operating system and turning on the equipment already presents this risk. In addition to reading information to load the work environment, temporary files, boot cache, boot records, and system logs can be written to the hard drive, causing loss of information due to the risk of overwriting.

Professional Recovery Services

If data recovery software fails or the data is extremely valuable, consider using professional data recovery services. These services have the tools and expertise to deal with more serious damages and situations that no software can resolve, leading the entire process in the safest path to have a positive end in recovering lost information.

Act quickly to increase the chances of a successful recovery. The longer the hard drive remains in use after problems are detected, the less chance there is of recovering lost data.


By following the essential steps to diagnose and troubleshoot a corrupted hard drive, you can minimize the damage caused by disk corruption and protect your important data. Always remember to make regular backups and keep your system updated to avoid future hard drive problems. We hope you find this guide helpful in dealing with this challenging situation and ensuring the safety of your files.
