Parity is the common technique used to detect system memory errors and it holds the similar functionality for RAID. The idea of introducing parity in RAID is to enhance data protection. Parity information is basically redundancy information that is calculated from the actual data values and is stored on a separate disk or across all the participating disks. But you may fall in critical situation of data loss if you lose this parity information. The only solution that allows you to get lost data back in such situations is

Parity is calculated as result of a logical operation, for example XOR or OR. The XOR operator gives true results if any of the operands is true. The truth table thus generated is used for mirroring redundancy technique. If you apply RAID parity, that will cost you high because data is duplicated over drives.

With every step forward in the field of , it is a fact that our systems are getting more vulnerable to data loss. From various system errors, physical breakdown, viruses, accidental or intentional deletion to disasters like fire or flood are common for big enterprises as well as individuals. We are the least concerned about regular backup and hence, the need for increase to minimize major personal and/or professional loss.

Prevention is always better than cure as data loss aftermath is more costly than the lost data itself. Living in a mechanical arena, preventing data from deletion is all most impossible. But with certain precautions, you can atleast prevent permanent data loss.

Just after encountering any data loss scenario, you should be extremely careful in handling the troubled system. And the motto is to avoid overwriting deleted files by new data as deleted files are not physically erased and by overwriting, the chances of recovery almost diminishes.

It would be very lucky that we have never had a hard drive failure, a system crash with data loss, or we would never delete critical files by mistake, but that sounds impossible. That’s why we need a data recovery. Data recovery software is kind of application which can renew lost files. While ideal data recovery software should be feature-riched providing you with exceptional recovery features to meet and serve different demands of users, and supports multiple types of hard drives and removable media. Moreover, it must be easy enough for a novice to handle, and extremely effective at retrieving lost data.

Here we recommend LeKuSoft Data Recovery, which is a multifunctional, powerful yet easy to understand data recovery software, it can recover deleted files and pictures directly recovered in hard drives, flash disks, memory cards (like SD cards, MMC cards, etc.), so long as data is not repeatedly written over. And it also enables users to preview recoverable picture in the lost picture lists for accurate and rapid recovery. What’ more, this data recovery program can help recover files from formatted partition, find the lost partitions and recover the relative data, repair corrupted Outlook, Outlook Express files, even recover damaged disk partitions to the raw status for more files.
