What are bad sectors on Hard disk?

Bad sectors are the affected sectors on hard drive that cannot be reused for storing data. Bad sectors and other hard drive issues are unavoidable irrespective of any brand or quality or price. Bad sectors reduce system performance and gradually decrease the storage capacity of the hard disk as it grows old. Data transfer becomes slow and computer often hangs out during data operation on the hard drive as a result of bad sectors. In such cases even disk checking utility fails to fix bad sectors on hard drive giving rise to loss of data.

What are reasons that are likely to cause bad sectors on hard drives?

There are various physical and logical causes for creation of bad sectors on hard disk drive as listed below:

    • Read/Write Head Damage: Excessive read/write operations performed hard drive can damage the read/write head on hard disk causing bad sectors on hard drive.
    • Repeated Power Failures: If there are frequent power failures when hard drive is performing read/write operation, it is going to affect hard drive severely. In addition, abrupt computer shut down due to frequent power failures can also cause bad sectors on hard drive resulting in the inefficient functioning of the hard drive.
    • Exposure to Overheat: When a hard drive is exposed to excess heat for many years, then it can create bad sectors resulting in loss of hard disk data.
    • CPU Overclocking: When computer hardware i.e. CPU works at speed greater than the manufacturer’s speed then it will gradually develop bad sectors on hard drive.
    • MBR Corruption due to Virus Attacks: Viruses/malware/spyware are the destructive programs that cam damage boot sectors of hard drive. You cannot access data from a particular sector of the hard drive when MBR gets severely infected.
    • Other issues: Software errors,configuration problems, OS crash, file system corruption, etc can create bad sectors on hard drive and lead to data loss.

    How to fix Hard Drive Bad Sectors

     

    Here I will try to explain how to fix Hard drive bad sectors .

     The first step is to do scaning Hard Disk to know the location of the damaged sectors (bad sectors), using one of the software contained in Hiren's Boot CD.

     

    Here are the steps:

    1. Booting is from Hiren's Boot CD for which you have.

    2. In the main view, select "DOS Program" 

    3. Then select the "Testing Tools"

    4. Then select "Test Hard Drive 1.0"

    fix Hard Drive Bad Sectors

    5. Then select "Auto Scan"

    fix Hard Drive Bad Sectors

    6. Then pillih hard disk which will be scanned

    fix Hard Drive Bad Sectors

    7. Then select "Surface Test"

    8. Wait until the scan is completed and we will know the results if there are bad sectors on the hard disk.

    If we know where the location of the damaged sector (see LOG), say his range is from 500Mb s / d 13GB. then inevitably we have to discard the damaged sector in a way which covers the range partitions made before, eg 0-15GB (exaggeration to make it more secure) then hide (hidden) so that the location of the damaged sector was not used anymore.

     

    Its steps are as follows: 

    1. Booting is from Hiren's Boot CD for which you have.

    2. In the main view, select "Mini XP" "

    3. Open the main program Hiren's Boot CD

    4. Select Program, Partition / Boot / MBR, Partition Wizard Home Edition.

    5. Delete Partition contained bad sectors, and then create / re-create the partition that covers the range of bad sectors, and then hide partitions (Hide Partition). then click aplly

    Wait a few moments to complete (100%)

    If you have software for hard disk partition such as Partition Magic, use it as long as it does not run on windows that troubled earlier.

    Reboot the computer and then Reinstall the Operating System on a clean partition (system).

     

    Usually this can last up to 3-4 months (depending on the strength of your hard disk) but have read the warning system SMART (Self-Monitoring, Analysis and Reporting Technology) hard disk. If that happens immediately backing up all your data and replace your hard disk ..!! because life is already hard disk will not be long (range 1-4 weeks).

     

    Hopefully useful.
