Advanced Linux Data Recovery Software

When any volume of your LINUX hard drive contains unnecessary data, which you do not want any more, you format it and store data afresh. Sometimes, due to operating system malfunction, file system corruption or any virus/malware infection, volumes get corrupted and cannot be accessed. In such cases, you need to format the troubled partitions/volumes, so that data can be stored and accessed normally. This is case, when you have to format the volume forcefully, which results in the loss of valuable data in the formatted partition. Apart from these, there are occasions, when you lose all your data because of any accidental formatting. In any such occasion, if you still want to recover your data back, you need to take the help of any linux recovery software.

The act of formatting is similar to deletion of data. In both these operations (Deletion and Formatting), the data from their location get removed and we fail to access them with any normal means. In case of deletion, the operating system simply removes the data from its source location, whereas in case of formatting, the data as well as the structure of the volume are removed by the OS. In both the cases, the operating system removes all entries of the deleted data and marks the memory location as free so that new data can be stored at the same location.

In this context, the interesting thing is that the operating system never completely erases the deleted or formatted data from the hard drive and even after such an operation, your seemingly lost data are very much present at their locations. If the lost or removed entries of the deleted/formatted data can be retrieved, then the data can be easily restored.

LINUX recovery software are developed with innovative techniques to find out the lost entries of files due to deletion or formatting of them. These utilities are efficient enough to read those lost entries and recover the files back. Moreover they are designed with completely read only approach and retrieve data in their original format, without any damage/modification neither to the data nor to the storage architecture of the drive.

Lost your Important Files in Linux?

Researches say that out of the many different reasons of data deletion, the most common cause is human mistake. Sometimes, it happens accidentally, whereas some other time, it is intentional. You were deleting some unwanted copies of photos, when mistakenly deleted the only copy of a memorable photograph. Similarly, you just deleted a folder and only after the deletion, realized that there was one important financial document in that deleted folder, which you need badly. While working on your LINUX system, such instances are not so uncommon and users do encounter them quite often. But, don’t worry! Even after such critical cases of data loss, you can still recover your data by using any good Linux data recovery software.

There are various instances of data deletion, including accidental deletion, intentional deletion of data or sabotage, deletion by virus attack etc. In earlier time, it was believed that once you deleted a data from the system, the data goes for ever and it can never be retrieved. But, one interesting truth regarding this myth is that recovery of a deleted piece of data is quite possible.

So, the question is what happens to the data that you deleted and how it can be recovered back? When you deleted a file from your LINUX system, the operating system removed all its entries from the system hard drive and marked the memory, allocated to the deleted data as free. But, remember that LINUX does not erase or overwrite the deleted data, until you save new files onto the same disk. Hence, if by any technique you can find out the removed entries of the deleted data and read them, the data can be recovered.

The LINUX recovery software do exactly the same. These software are developed with highly advanced scanning algorithms. When you run the software, these scanning algorithms dig your hard drive/volume in all possible ways and read the lost/removed entries. By using those lost entries, the software recovers the deleted or formatted data back.

These Linux data recovery software are absolutely read-only in their operations and never alter the structure or format of the data in the drive. Moreover, the utilities are developed with such user friendly user interfaces that they can be used by professional programmers as well as non-technical home users.

How to Recover Data after Encountering Error – GRUB 17

Error – GRUB 17: Recover data

The Grand Unified Bootloader or GRUB is a package from GNU that facilitates implementation of multi-boot operation. With GRUB, you can install more than one operating system on your LINUX based computer and have their benefits. GRUB also facilitates viewing various hard drive partitions, repartitioning, modifying partition settings etc. However, sometimes it flashes error messages indicating problems in the hard drive, following which all the data in the data become inaccessible. In such situations, you can execute any data recovery LINUX utility to recover the seemingly lost or inaccessible data back.

You tried to boot your LINUX system and the system became inaccessible after displaying a GRUB error message. The error message, you may have encountered can be read as -

“GRUB Error 17: Cannot mount selected partition”

There can be a number of possible reasons behind the occurrence of the above error message, such as:

Though the requested volume/partition exists, but GRUB fails to recognize the file system.
The boot device set in the file '/etc/fstab' is incorrect.

Note: '/etc/fstab' stores information regarding connected disks as well as their partitions and provides the same to the system, when any drive is mounted.

GRUB has tried to boot a partition with severe corruption or damage to the file system.

Solution:
The following work around may help you resolve the above issues:
If the file '/etc/fstab' has been found with incorrect boot partition, try to edit and provide the correct boot partition.
If the file system has been found to be damaged or corrupted, run the 'fsck' command-line utility to locate and fix the errors.

If both the above option fails to solve the problem, you need to format the drive and make fresh partitions. With partitioning, all your data in the drive gets lost and you have to restore them from an updated backup. In case, you do not have a valid backup, you can still retrieve the formatted data by running any LINUX data recovery software.

These linux data recovery software incorporates many advanced techniques to read the lost entries of the formatted files and successfully recover them back. These software are extremely read-only in nature and with interactive user interfaces, quite easy to use.
