Poor quality: Hard drives with low quality tend to have shorter overall lifespan and develop bad sectors.Dropping hard drive or laptop to floor, excessive collision or knocking, especially when disk is working, can lead to severe physical bad sectors. 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.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. During this process, head is likely to touch or rub disk platters, damaging that area and causing bad sectors. When sudden power failure or improper system shutdown happens, heads in hard drive will be forced to back to situ. 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.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. Aging devices: Like other electronic devices, hard drive has an expected life span.Here are some factors that can cause bad sectors: To prevent bad sectors, you need to know the most common reasons behind it. Bad sectors are no longer available for data storage and cause data loss most of times. Sectors on hard drive can easily get damaged due to all kinds of reasons.

What can cause bad sectors in a hard drive? If it shows the hard drive is failing, the disk is likely to have bad sectors.

Computer takes ages to start up or system booting always ends up with a blue screen of death.

If you know the warning signs beforehand, you have a good chance to prevent disaster. Likewise, everything else, hard drive bad sectors give signs and symptoms. If not taken proper care, data would be at the risk of loss. Hard disk might be one of the most fragile hardware among computer components. How do I know if my hard drive has 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.

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. Logical / soft bad sectors are sectors on hard drive that appear to not be working properly. This type of bad sector cannot be repaired, but it can be prevented. As to solid-state drive, bad sectors are the result of worn out flash memory cell or other defects. 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. If a hard drive's head touches the rotating plater, that area will be damaged. Physical / hard bad sectors are a cluster of sectors of the hard drive that are physically damaged.

There are two types of bad sectors – physical (hard) and logical (soft) bad sector. In fact, it is very common that disk used for a long time has bad sectors. These phenomena show that there must be bad sectors on the disk. 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.
