Incorrect Application of dd Command May Cause Data loss in Linux

Posted on November 18, 2009

In Linux computers, dd (data definition) command-line utility offers several advantages such as converting raw data or low-level copying of data from hard drive to any other storage media. The command is used to copy the file system and is capable of copying specified number of data blocks or bytes. Furthermore, this tool allows you to copy data blocks rearwards, so that in case of any problem in block at some point, data that is stored after and before string would be copied. But incorrect use of parameters in this command may lead to serious data loss situations and need Linux Data Recovery to be sorted out.

This is a useful command-line tool in Linux that helps you to carry out quick and easy recovery in case of any damage to your system and data loss. This command enables you to create image of even entire Linux volume and restore it in case of any damage. On new hard drive, target partition is created having same size and structure as of the failed one. Then this utility is used for copying data from source drive.

Although, the process of this command it quite safe and easy, but a minor mistake during operation might cause disastrous situations. Performing low-level operations on hard drive, if the ‘of’ and ‘if’ parameters are get reversed accidentally. This behavior of Linux operating system renders all of your valuable data inaccessible and cause data loss. At this point, you need to perform Linux Recovery by resolving it to access your valuable data.

You much also consider the block size that has to be copied. The cont=noerror, synchronization option that is used to copy data and files, ignores remainder of block and then replaces it with zero bytes. Thus if block size is large, complete Data Recovery Linux could not be guaranteed.

In such situations, you need to methodically scan the entire hard drive using powerful and advanced scanning algorithms. This is best possible using efficient and highly automated third-party Linux Data Recovery software.

The applications come equipped with simple and self-descriptive user interface and thus let you carry out recovery on your own, without demanding sound and prior technical skills. They are built-with read-only and non-destructive conduct and thus do not alter original data on the drive.

Stellar Phoenix Linux Data Recovery is the most effective solution for all your data loss problems. The tool recovers data from all Ext4, Ext3, Ext2, FAT12, FAT16 and FAT32 hard drive volumes. It works well with all major distributions of Linux operating systems including Fedora, Red Hat, Debian, SUSE and Ubuntu.
