Hard Drive Data Recovery- Defect Mapping And Spare Sectoring
In spite of the preciseness manufacturing procedures used for creating the hard drives
, this is practically impossible to manufacture a hard drive with millions of sectors and no errors. Imperfections in hard drive media coating and other issues may make the sectors inoperable. An issue with the hard drive sector, if not fixed, generally manifest as error while trying to read data from and write data to hard drive. Such behavior of your hard drive may lead to critical data loss and require Hard Drive Recovery to be sorted out.
Modern hard drives use ECC (Error Correcting Code) to help you identify if errors take place and resolve them. However, ECC can not fix the physical problems and thus prevent parts of the hard drive from being used. Generally such are the individual sectors, which do not work and are known as bad sectors.
The hard drive sectors, which are bad and can not be used for storing the data, because they are not reliable to write data. It is thus required for your system to keep track of which hard drive sectors are bad and not to use them. The most excellent method for it needs to be done for hard drive for detecting and avoiding them. If the bad sectors aren't detected before they've been written, data loss may occur.
At the time of manufacturing, every hard drive is systematically tested for the areas that may have errors to ensure maximum reliability. The process of detecting and removing hard drive bad sectors are known as defect mapping. When bad sectors occur on the drive, you may also feel that your system performance is decreasing.
Bad sectors on the modern hard drive are generally an indication of critical problems with the drive. If a newly purchased hard drive has bad sector, you should get it exchanged. If you see bad sectors on the older hard drives while scanning the drive, you need to get it fixed. The bad sectors result data loss in any form and require
hard drive data recovery to be handled.
Hard Drive Recovery Software can be used to work around logical data loss problems. You can create image of the drive using these applications and perform easy recovery on bad sector affected drives. The Hard Drive Data Recovery applications are completely easy and safe to use with simple graphical user interface and read-only conduct.
Stellar Information Systems Limited offer high-quality recovery solutions to handle all types of data loss situations. The software are offered for Windows, Mac OS X, UNIX, Linux, and Novell operating systems. Service is delivered through Class 100 Clean Rooms using cutting-edge technologies.
