Technology And Computer|

Linux is basically a command based operating system, where, there is a command for each operation and users, who use  Linux based computers are usually known as more technically sound individuals. But, however tech savvy one may be, accidental deletion of data is quite common even in case of  Linux systems. Moreover, sometimes while resizing partitions with various third-party utilities, important existing  Linux partition gets accidentally deleted causing a serious data loss situation. In such a case of  Linux data deletion, a  Linux data recovery software can help you recover your lost partition back.

Users make multiple logical partitions to a single hard disk drive for the convenience of data storage. Moreover, Linux operating system based computers are often with multiple partitions and each of the individual partition has a fixed size. It is quite common that the need of partition space changes and hence, the need to resize the partition arises. Though, there are several partition resizing tools for  Linux systems do exist, there lies a number of potential risks of partition loss as well. Therefore, the whole process of partition resizing becomes more complex than it actually seems.

There can be a number of causes behind the loss or deletion of a partition, while partition resizing. Moreover, the user must gain enough knowledge before dealing with the partitions as they contain your valuable data. However, once, your  Linux partition gets deleted, you can be able to restore it from your previous valid backup. In case, you do not have any good backup or due to any unresolved reason, failed to restore data from the backup, then, you have to take the help of an efficient  Linux Partition recovery software to recover your lost partition back.

Linux recovery software are designed to recover all your lost, deleted, formatted or inaccessible  Linux based partitions or volumes with ease. These utilities are powerful enough to scan the drive, locate your lost partitions and recover all the data from them. Moreover, with detailed instructions based graphical user interface, these utilities are simple in usage even for the users, who are not so proficient in terms of computer technology.

Linux is the UNIX like operating system that uses the Linux kernel of Monolithic type. The OS is being installed on a vast range of tablet computers, mobiles, video game consoles, mainframes, super computers etc. Even, statistics says that as, server OS, LINUX accounts more than 50% of the whole global installations. Also,over the years, Linux operating system has gained fair amount of popularity among the common home users with the Fedora, Ubuntu and OpenSUSE distributions. Moreover, with the egression of smart phones, netbooks etc, which are running on embedded LINUX, the operating system has been more closely used by many users. Though Linux has advanced technology and features, sometimes, some errors  lead to data loss or inaccessibility and you need to look for any Linux data recovery software to recover back your valuable data.

In day to day usage of a Linux system, there can be enormous possibility of data loss situations, and you may not always successful in trouble shooting the system to gain access of your data. Hence, if you don’t have a valid backup available or failed to restore the data from the backup, Linux recovery is the answer to bring back your data.

Common data loss situations in Linux:

Error – Mount wrong fs type, bad option, bad super block on /dev/hdb2.
Error – Too many mounted file systems.
File system error.
Grub Error 12 – Invalid device requested.
Grub Error  17 – Can not mount selected partition.

There can be many such errors leading to the loss or inaccessibility of your Linux data. In such cases, if you are a technical person, then you can trouble shoot at the low-level. You can  run the ‘fsck’ command to detect and fix such error. Prior to running the ‘fsck’ command, first, you need to go to the single user mode. Then, you have to unmount the file system partition, you are going to work upon, if it is not the root file system. If you don’t take enough care to unmount the file system, the ‘fsck warns you, such as- ‘The file system is mounted, do you want to continue anyway?’ Saying yes to the message, may result in the loss of your data, because, at times, ‘fsck’ writes directly to the disk.

If you need to check the root file system based partition, you have to boot the system in single user mode and run the ‘fsck’ with a ‘-b’ option so that it will run in a read-only mode. Also, the ‘-b’ option directly go to the ‘init’ and makes an emergency booting while skipping the other start-up scripts.

Sometimes, ‘fsck’ fails to run or exits without running at all. At that time, you need to force run the utility with ‘-f’ option. This is a case of severe corruption and you need to give additional information to ‘fsck’, such as the size of the alternate superblock or the address of the superblock to fetch the data and fix the error.

However, sometimes, these low-level recovery process is tedious as well as risky with respect to your valuable data. Hence, you can go for any Linux data recovery software, which can recover the data for you safely.

The LINUX operating system is very much similar to UNIX and has derived many basic design principles from it. Day by day, LINUX OS has improved upon its previous versions and indeed has incorporated a number of distinguishable features over other operating systems. In LINUX, disk drives are mounted through file system volume label and not the device path. This is a newer concept applied in LINIX in order to avoid the ambiguity in distinguishing after a disk has been removed and some other have been inserted with the same device path. However, if there is corruption to the volume label, the situation becomes more complex, keeping the data from the drive completely inaccessible and a LINUX data recovery utility is a must to recover the inaccessible data.

To be a bit more elaborative, suppose, your system disk is at /dev/sda2. The system may have mapped another disk as /dev/sda2 and hence, your fstab, where all entries of the mounted disks are there, will be messed up making your system start improperly. At times, such issues can cause huge loss of data.

These kinds of situation may fire the command fsck automatically to check the LINUX volumes each time the system boots-up. As fsck, checks for file system errors and tries to repair the same, it may take a significant amount of time. Any power surge or system crash during the process may cause serious system instability and data loss. This is an added problem that may further flash a warning message and further increase the chances that your LINUX volumes become inaccessible. The message may read as below:

“Warning: invalid flag 0×0000 of partition table 4 will be corrected by w(rite)”

The warning message tells that the disk label has been corrupted and that is why the data in the drive is inaccessible. If running Disk Utility or fsck command fails, you have to restore the data from the backup. However, if backup of your data is not available, run a reliable Linux disk recovery software to recover the data.

LINUX data recovery software are designed with powerful scanning algorithms that can recover any deleted, formatted or inaccessible data with ease irrespective of the data loss situation.

Among many names, Stellar Phoenix Linux Data Recovery is tried and appreciated by many users. The application can successfully recover your lost, formatted or inaccessible data from FAT32,FAT16,FAT12,Ext3,Ext4,Ext2 file system based LINUX volumes.
