In this article, we will look at the detailed HDD repair process and share with you with information about how you can recover data even in a hard-damaged drive. However, before we recommend that you familiarize yourself with some technical information that will allow you to understand the essence of the problem.
It is difficult to overestimate the role of information in the modern world. Not only the level of our knowledge depends on it, but also, often, a professional career – something that is always given by great difficulty. Any damage to the physical drives of the computer can lead to the most unpleasant consequences, including the device failure and the complete loss of personal data. What to do if there are damaged sectors on the drive and there is a risk of its permanent failure?

What is a damaged sector?
A damaged sector is a specific hard drive space that cannot be used due to its physical damage or being unable to be accessed. This problem manifests itself primarily in the slow operation of the HDD, the inability of the system to fully boot up and the WIndows failure to request formatting the device. The occurrence of these phenomena can confidently indicate the presence of bad sectors on the drive.
Types of HDD damage
There are only two types of damaged hard drive sectors: physical and logical. Let’s look at them in more detail.
A physically damaged sector is a hard drive cluster that has been physically damaged. If the HDD head touches the rotating plate during operation, then it is guaranteed to be damaged. Repairing such a sector is impossible.
Logically damaged sector is a cluster that has stopped working properly. When the operating system tries to read data from it or write new ones, it encounters an error and is unable to interact with the sector. Such sectors can be easily restored.
Signs of HDD Damage
The hard drive is probably one of the most fragile components of a computer. If you do not properly monitor its condition, sooner or later a failure may happen resulting in a complete loss of data. Just like any other device, the HDD has its own unique symptoms that signal about errors. Let’s look at some of the signs that indicate obvious damage to hard drive sectors.
- Significant increase in data processing time. The PC performance slows down or it stops operating completely.
- The hard drive file system acquires RAW status. When you try to connect to it, messages about the unavailability of the device appear on the screen.
- HDD makes unnatural sounds while operating.
- At the time of formatting the drive, the operating system displays a message with “Windows could not complete formatting” error.
- The operating system is unable to boot. Any launch attempt ends with a blue screen of death.
- Periodically “Windows has detected a problem with the hard drive” error appears on the screen, which suggests making a backup of the data.
Causes of bad sectors
Hard drive clusters can be easily damaged for a variety of reasons. They can significantly complicate the work with a PC or even lead to the fatal damage of a hard drive. To prevent this problem, we recommend that you familiarize yourself with some common causes of its occurrence.
- Obsolete hard drive.
Like any other device, a hard drive has its strictly reserved service life and after it expires the likelihood of various kinds of errors increases significantly.
- Incorrect computer shutdown.
Due to the high rotational speeds of the components of the hard drive, a sudden reboot or power down can cause the HDD head to touch the plate and cause physical damage.
- Shaking and hitting the hard drive.
Despite the fact that manufacturers of HDD in every way seek to strengthen the design of their devices, careless handling of them can easily lead to serious damage.
- Device contamination.
Dust – is one of those causes of bad sectors, which is the the last to go. If inside the device enough dirt had accumulated, damaged clusters will immediately appear in the hard drive.
So, we have dealt with the technical side of the question and now it is time to start the practice!
Starus Partition Recovery – Data recovery from a damaged HDD
Unfortunately, in some cases it is simply impossible to save a hard drive. It’s performance degrade dramatically and, perhaps, it has no more than a few days left to work. Therefore, the only important task for the user is saving personal data.

Do not, under any circumstances, export documents to the drive from which you are restoring. This action may lead to their permanent loss.
HDD scanning and repairing
As you probably know, there are a large number of various applications which aim to help the user checking and repairing a damaged drive. However, not all of them are efficient or accessible to understand the interface, which to some extent complicates the recovery process of the device. Therefore, we have prepared for you a list of the best applications for HDD repair on our opinion.
