Hard Drive RecoveryCorrupted Hard Drive

Data inaccessibility on a hard drive can occur for various reasons. One of the most common causes is the bad sector. A bad sector on a hard drive is a small piece of disk space that fails during operation. Such a sector does not respond to read or write requests.

There are two types of bad sectors, categorized based on the reason for the occurrence. Some result from physical damage to the drive and often cannot be repaired. Others are the result of software errors and can be easily fixed.

Hard Drive Bad Sectors Types

As was mentioned before, there are two types of bad sectors: physical and logical. These sectors occur due to various reasons but result in the same complication for the user – data loss. There are various features that help distinguish these two types of bad sectors.

Physical bad sectors occur on the hard drive after physical damage. The read/write heads of the hard drive may have come into contact with the platter, scratching the data of the disk. The damage can also occur if dust or moisture inserts the inner part of the drive.

Logical bad sectors are spaces on your hard drive that are not working correctly. The operating system is not able to read data from such a sector, and neither can it write the data on the bad sector. Such sectors are marked as corrupted, and OS will no longer use them for storing information.

What Causes Physical Bad Sectors

A bad physical sector is considered a severe problem for a user and can occur for various reasons. Your hard drive may have bad sectors due to manufacturing errors. Another reason for physical bad sectors occurrence is physical damage when the heads of a hard drive damage the magnetic platters.

What Causes Logical Bad Sectors

Software errors cause logical bad sectors. For example, if the power is turned off while writing data to the hard drive, a sector gets interrupted in the middle of the operation and becomes corrupted. Viruses and other malicious software can also cause system errors and bad sectors.

Data Loss on Hard Drive with Bad Sectors

Even if your hard drive continues to work correctly, your data can be seriously damaged, resulting in the loss of important information. Only having multiple backups on different media can keep you from losing data due to bad sectors or other disk failures. However, if you do not have a copy of your data stored somewhere safe, you will face severe consequences.

Hard Drive and Heads Recovery

When a computer detects a bad sector, it will ignore it. The data in that sector will be moved, so the system will neither read this sector nor write on it.

Modern hard drives support S.M.A.R.T. technology and record the number of affected sectors. However, it is possible that the contents of a bad sector cannot be read or moved.

This way, the file will become corrupted and inaccessible to a user. A hard drive can have a few bad sectors, which will not influence its performance. However, if the disk’s bit sector count regularly increases and your computer warns you with error messages, you should pay attention to the drive and take appropriate steps as soon as possible.

What to Do When Facing a Data Loss due to Bad Sectors

Several warning signs can inform a user about bad sector problems on the hard drive. Frequent error messages, corrupted files, unusual noises, and slow performance are some of the common signs of data loss on your device. When noticing it, you can scan the device to understand whether file inaccessibility is caused by bad sectors or other reasons.

When ensuring that the device is exposed to data loss, there are several actions a user should perform. Powering down the device must be the number one step for each failure and data loss scenario. Continuing to use your device is very risky and can cause more issues.

When facing a physical bad sector, do not try to open the drive and replace broken components. Only professionals with years of experience can approach this case and carefully restore data from a physically damaged device. If a bad sector occurs due to a logical problem, it is essential not to use data recovery software to fix the bad sector or save the data. Using a recovery program can overwrite your valuable files, making them permanently lost.

Hard Disk Drive Diagnostics

Moreover, free downloading and installing an unverified tool on your fragile device can insert viruses, so recovering data from it will become more complicated.

The most effective strategy, in this case, is to entrust the device to a professional data recovery company. This way, you will get all the valuable files back.
