Hard Drive: Bad Sectors Overview
Each hard disk includes many sectors. Those that are unreadable or damaged are called bad. Due to many reasons, sectors can be damaged one by one. And the more bad sectors on the hard drive you have, the slower the hard drive will work. In the end, when the bad sectors on hard drive are more than the good ones, the device simply stops working. Often, in such situations, the user does not know what to do.
You can learn in this article how to fix bad sectors.
Signs That You Need to Scan for Bad Sectors
A hard disk stores a huge amount of information and if it gets corrupted due to a bad sector, it may cause you to panic. Fortunately, the hard drive does not stop working without warning; before this, there are some symptoms that will help you to recognize that something has gone wrong. Once you know these signs may help you avoid bad sectors on hard drive.
Here are some of the main symptoms:
When you try to open a disk, you see error messages like this: “Location is not available.” “Drive: D is not available.” “Data Error.”
Hard drive is read as RAW.
Applications take a very long time to open.
The hard disk itself produces unusual sounds when working with it.
You cannot complete the formatting of the disk and receive the error message “Windows could not complete formatting”.
Restarting the computer is taking longer and longer.
If you are dealing with these signs, it means that you have bad sectors on hard drive and, at any moment, the hard disk may stop working.
Bad Sectors: Physical vs Logical
You need to know whether your sectors have physical damage or logical. This greatly affects the ability of performing bad sector repair on your hard drive.
Physical damage to sectors is mechanical damage to the constituent parts of a hard disk (for example, damage to a hard disk head). Unfortunately, fixing bad sectors in this case is impossible, but it can be prevented by properly handling the hard disk.
Logical damage to sector mean that the disk does not work, but in fact is easy to fix. The sectors are marked as damaged when the OS tries to read them, and the codes do not match. Later, we will show how bad sector repair in such cases can be done.
Reasons that Lead to Bad Sectors on a Hard Drive
1. Any hard disk has a lifespan. Perhaps your hard disk has been in use long enough and therefore bad sectors have begun to appear.
2. A dirty and dusty hard drive sooner or later will also have bad sectors.
3. Sudden and improper shutdown of the computer can easily damage sectors. In the event of a sudden power outage, the head should quickly return to its original position and at the same time touch or even wipe the disk plate, which will inevitably lead to damage to the sectors.
4. Careless usage of the hard disk. When hit or shaken, the hard disk can be damaged. This is most relevant to laptops.
5. The hard drive itself may be of poor quality and from an unknown manufacturer.
Here the outcome of using such a hard disk is generally unpredictable. So, what should you do with bad sectors? How do you perform bad sector repair?
