How to retrieve files from Bad Sectors?


Disk drives are divided in to millions of sectors. These sectors are nothing but small spaces which stores our data. The main reason behind this is to organize the data in an effective way so that read/write head can easily access it. These physical sectors on the disk drive may eventually fail causing the computer to behave in erratic way they are known as bad sectors. Bad sectors are the sectors on the hard disk or external hard drive that have become unusable or unreadable. Normally these sectors are detected and flagged as “unusable” by disk utility software such as CHKDSK or SCANDISK on Microsoft system. Bad sectors are automatically masked by the operating system so they are hard to identify. However that is certainly a bad sign. Only remedy in this situation is to use data restore utility to get back the data stored on these bad sectors

Bad sectors may arouse due to following reasons::

  • Bad Parity Checking Bits: Parity checking is a technique used to detect any memory or data communication errors. Most of the modern disks while storing the data will eventually store parity bits along with data. When the data is read, the parity bits are also retrieved and compared to ensure data integrity. If the parity bits are corrupted for some reasons, it will result in bad sectors.

  • Cross Linked Files: Bad Sectors are usually caused by cross linked files which are the result of operating system overwriting a portion of one file with another file. Potential causes of cross linked files are turning off or restarting your computer suddenly without following system commands, file system errors. This issue may also occur if you do not defragment the disk regularly.

  • Physical Damage to the disk: Physical damage or shock can even lead to the generation of bad sectors on disk drive. If the head of the drive comes in contact with the hard disk drive platter then platter experiences a strong jerk and gets damaged which might in turn creates bad sectors.

  • Malware Attack: Malware include adware, spyware which infects and corrupt hard disk. Virus usually overwrites the beginning of the sector with the same code that the file system uses to indicate a bad sector. Thus the sectors are changed by the virus to indicate the operating system that the sectors are bad.

Symptoms of bad sectors on your drive:

  • Files become mysteriously corrupted.
  • System becomes very slow or freezes up when you try to access the files.
  • In severe cases entire disk becomes inaccessible.

Bad sectors affect important data stored on the disk and if the system continuously reads these sectors the risk of system crash increases. Bad sectors ultimately decrease the life of the disk and make it become dead. So it recommended to retrieve data stored on these bad sectors before you land in entire data loss from the hard disk. Usually recovering the data from these bad sectors is very difficult to handle. Only commanding and efficient tool like data retrieval utility can handle this situation and helps you to recover data from the bad sectors. This application is equipped with advanced algorithm to retrieve data from the bad sectors by creating the “disk images” of the bad sectors. Later you can easily recover data from these disk images. It supports data recovery on Windows 7, Windows XP, Windows Vista as well as Mac operating system. It has a signature search option to locate and restore different types of files from the disk with bad sectors.Furthermore, it can also restore accidentally deleted files from USB drive, memory sticks and all other storage drives.

With the help of this data recovery software it is possible to retrieve data from deleted partition, lost partition, inaccessible partition, formatted, re-formatted partitions with in a quick span of time. This application performs sector by sector scanning of the drives to get back the data from the partitions. It is one of the best hard disk data recovery software which efficiently rescues data from different types of hard disks such as SATA, SCSI and IDE. It restores data from different hard drive brands like Fujitsu, Seagate, Maxtor, Western Digital and many more.In case, if you want to know how does this software restores data from RAID partitions, then visit here
