The Best Top 5 Hard Disk Bad Sector Removal Software's | Data Recovery | Repair Bad Sector in Hard Drive | Recover Data from External Hard Drive.

The hard disk role in a computer system can't be argued as it is where you will store the operating system and other files. Though other storage devices like USB flash drives, CD/DVD, etc., can't be used to keep the operating system for one or other reasons. Hard drive bad sectors make the hard drive inaccessible to read and write operations and are very common. The bad sectors' data may be lost temporarily and permanently depending on the cause, i.e., hardware or software. Hardware errors are impossible to fix, and it would be best to back up the hard drive and replace it. Software errors can be corrected with a software application designed for a specific task.

Error Checker will automatically run the disk checkup when you boot the system the next time.

Part 3. The 5 Main Reasons May Cause Hard Disk Bad Sector

1. Virus Attack May Cause Hard Disk Bad Sector

Virus infection is one of the main reasons that can cause hard disk bad sectors. Many viruses can remove or modify system registries and file system table. If they release a link to a file or folder from the system registry, it will become inaccessible. Viruses can cause logical hard drive bad sectors, but they can't damage the hard drive physically. Generally, repairing destructive analytical industries are more comfortable to remove, and for physical damage, you would need to replace the hard drive. Removing the viruses from the system will solve any lousy sector errors on your hard drive.

2. Sudden Shutdown May Cause Hard Disk Bad Sector

The hard drive uses physical parts such as drive heads to read and write the data on it. When the aim is active, it always moves from one location of the hard drive to another. If you don't correctly shutdown the system, the drive head may damage the disk. Once the hard drive is damaged, the damaged part won't be available for reading and write operations and cause bad sectors. Moreover, this type of physical hard drive bad sectors can't be repaired. They should be marked off-limits for write operations as the data may not be written and gets lost. Blue Screen of Death error may also cause a sudden shutdown.

3. File System Error May Cause Hard Disk Bad Sector

The data on a hard drive is stored adhering to a specific design. The file system does the task of allocating space to a file, and an error in the file system can compromise the whole system integrity. Some parts on the hard drive may become inaccessible for reading and write operations. You can use the chad utility on Windows to scan and fix file system errors.

4. Excess Heat May Cause Hard Disk Bad Sector

Heat is the enemy of every computer component, and the same is the case with the hard drive. Hard drives are not meant to be used at high temperatures as the disk can get damaged. Moreover, it can damage other internal components in the hard disk. So, hard drive bad sectors can be caused by overheating, and if you don't want to lose data due to this, use the hard drive at optimum temperatures.

5. Age

Every hard drive suffers from wear and tear with use and has a fixed life. If you haven't replaced your hard disks for a long time, your data may be at risk. Hard Drive accumulates some damage over time, and this can cause hard drive bad sectors. The rate at which this can occur depends on how you use it, but it will give in someday. So it is better to keep a backup of your data so that it can be recovered in case your hard drive fails.

Part 4. How to Recover Data from External Hard Drive

The major problem with hard drive bad sectors is that it can make the data stored inaccessible, making it permanently lost. That is why you need the Recoverit Data Recovery to recover data from corrupted hard drives, USB flash drives, memory cards, and others.

Overview on bad sectors

What is a hard drive bad sector?

A bad sector is a sector on a hard disk that cannot be used due to permanent damage (or an OS inability to successfully access it), such as physical damage to the disk surface (or sometimes sectors being stuck in a magnetic or digital state that cannot be reversed) or failed flash memory transistors. Something weird will happen if the hard disk has bad sectors, for instance, operating system cannot boot normally; hard disk can't be formatted; when you open a file, error is reported. These phenomena show that there must be bad sectors on the disk. In fact, it is very common that disk used for a long time has bad sectors. There are two types of bad sectors – physical (hard) and logical (soft) bad sector.

Physical / hard bad sectors are a cluster of sectors of the hard drive that are physically damaged. If a hard drive's head touches the rotating plater, that area will be damaged. For example, your computer gets bumped while its hard drive is writing data, hard disk is exposed to extreme heat, or some mechanical part fails, all these are likely to cause hard bad sectors. As to solid-state drive, bad sectors are the result of worn out flash memory cell or other defects. This type of bad sector cannot be repaired, but it can be prevented.

Logical / soft bad sectors are sectors on hard drive that appear to not be working properly. When operating system tries to read or write data stored on these sectors and finds error correction code (ECC) which does not match content of the sector, that indicates that something is wrong and these sectors may be tagged as bad sectors. Soft bad sectors are repairable by overwriting on disk with zeros, which can be done by bad sector repair software such as DiskGenius.

How do I know if my hard drive has bad sectors?

Hard disk might be one of the most fragile hardware among computer components. If not taken proper care, data would be at the risk of loss. Likewise, everything else, hard drive bad sectors give signs and symptoms. If you know the warning signs beforehand, you have a good chance to prevent disaster. Let's look at some signs telling hard disk probably contains bad sectors.

Drive becomes RAW and inaccessible. When you try to access it, you receive error messages such as "Location is not available. Drive: \ is not accessible. Data error (cyclic redundancy check)".

It takes a long time to run a program or read data, or software stops responding frequently. Computers slows down or freezes when the damaged hard drive in connected.

Hard drive makes strange noises when computer boots or you try to access data in this disk.

When you want to perform a quick format to the device, formatting fails with error message "Windows was unable to complete the format".

Windows keeps popping up a messaging telling "Windows detected a hard disk problem" and suggesting backing up data.

Windows slows down and BSOD. Computer takes ages to start up or system booting always ends up with a blue screen of death.

S.M.A.R.T. information. There are tools that can read S.M.A.R.T. data of hard drive. If it shows the hard drive is failing, the disk is likely to have bad sectors.

What can cause bad sectors in a hard drive?

Sectors on hard drive can easily get damaged due to all kinds of reasons. Bad sectors are no longer available for data storage and cause data loss most of times. To prevent bad sectors, you need to know the most common reasons behind it. Here are some factors that can cause bad sectors:

Aging devices: Like other electronic devices, hard drive has an expected life span. If your hard drive has been used for a long time, it is likely to be wearing out and bad sectors might have been created over time.

Turn off computer improperly: Platters in hard drive rotate in a high speed when working, as heads have to read data from different location on the disk. When sudden power failure or improper system shutdown happens, heads in hard drive will be forced to back to situ. During this process, head is likely to touch or rub disk platters, damaging that area and causing bad sectors. In a similar way, if external hard drive is unplugged from computer directly without using safely removing hardware, bad sectors are likely to be caused.

Shaking or knocking: Though many manufacturers have tried their best to enable to enable the shock-resistant function, it does not mean you no longer need to worry about shacking or striking. Dropping hard drive or laptop to floor, excessive collision or knocking, especially when disk is working, can lead to severe physical bad sectors.

Poor quality: Hard drives with low quality tend to have shorter overall lifespan and develop bad sectors. Such kind of hard drive probably contains bad sectors when it is produced.

Dust: Working in a dusty environment is one of the most common causes that are often overlooked by users. As heads are very close to disk platters, if any dust falls into the disk, bad sectors will occur soon.

Check and Repair Bad Sectors

Free software to check and repair bad sectors

 

Is it possible to check or repair bad sectors on hard drive and USB drives? The answer is YES. There are bad sector check and repair tools online, and you can download one of them to help you perform a surface scanning. Besides, it is still possible to recover files from a damaged hard drive caused by bad sectors. Let's see a free bad sector repair tool – DiskGenius Free Edition.

How to repair bad sectors using free bad sector repair tool?

Important:

Checking bad sector is read-only process and does not affect disk itself or files on hard drive, however, repairing bad sector is a different story. Before trying any bad sector repairing solution, make sure you have a good backup of your files on the damaged disk, as repair action probably result in the loss of files or corruption of file system.

Repairing bad sector is of no help to data recovery. The bad sector repair destroys data on the disk; more exactly, it destroys data on bad sectors or near bad sectors. Thus, you need to back up data before the bad sector repair. It is common that the disk cannot read data due to bad sectors, and in such a condition, you need to recover data first instead of doing the bad sector repair.

Not all bad sectors are repairable such as physical bad sectors. If DiskGenius cannot repair all bad sectors on your hard drive, you can isolate bad sectors by creating a partition on the disk area that contains bad sectors and hiding the partition with the help of DiskGenius.

Step 1   Click Repair button if you want to repair bad sectors on the "Bad Track Verification" window.

Step 2   You'll receive a warning that asks to back up data first. If you have created a backup for important data, click OK button. If not, click Cancel and backup your files.

Step 3   Another warning message from DiskGenius, which tells repairing bad sectors does not equal to recovering files and you should recover data first.

Click OK if file recovery is not needed. If you want to recover data, you should click Cancel and use File Recovery function to scan the disk to find lost data.

Questions and answers about bad sectors

1. Why hard drive gets bad sectors?

One of the reasons is that hard disk has bad sectors when it is manufactured; experienced data recovery engineers know which disk is likely to have bad sectors judging by its brand, manufactured time, working hours, etc. Another reason is the improper operations such as unduly defragment.

2. Do I need to fix bad sector issue as soon as possible?

Yes! It will become a vicious circle if you do not fix bad sectors timely, because that may cause more bad sectors. Therefore, you'd better detect bad sectors regularly and do bad sector repair timely. Meanwhile, though bad sectors are fixed, the disk is riskier of getting bad sectors than normal ones. So, you should be cautious when you use a disk that had bad sectors before and do not save important data on it. The logical bad sector can be fixed, while the physical bad sectors cannot be repaired, but usually they can be remapped. Bad sector repair and detect software can detect bad sectors, repair logical bad sectors, and remap physical bad sectors.

3. Can bad sectors be fixed via low-level formatting (LLF)?

Low-level formatting can be used to fix server bad sectors. However, the low-level formatting is a double-edged sword; it can fix bad sectors as well as do hard to hard disk, especially when the hard disk has physical bad sectors. Thus, the low-level formatting is the last choice of bad sector repair.

4. Is it possible that a new hard drive contains bad sectors?

It is barely known that when a hard disk is manufactured, there are areas on the platter that have bad sectors! These bad sectors, hidden in P-LIST and G-LIST, will not affect normal use and they can't be accessed by common software either. G-LIST can store several hundred bad sectors and the P-LIST can store about four thousand bad sectors. For more information about G-LIST and P-List, please read related articles. One thing to note if your hard drive contains irreparable bad sectors, it is not advised to store importance data on that disk for data security reasons.

Conclusion

It is a common occurrence that your hard drive or other storage devices develop bad sectors, and there is no need to be panic when you run into such issues. You can use DiskGenius Free Edition to easily check or repair bad sectors. In addition, do not forget to create backups for important files and keep backups on different disks in case that one of them fails to work.
