In case of a Linux operating system based computer, sometimes, the system fails to boot following any unsystematic system shut down. The reason can be anything from a possible file system corruption to an operating system malfunction, but at the end of everything, it is your valuable data in the drive, that has been inaccessible and you need to run any Linux data recovery software to recover them back.
Boot errors are always critical, as once you encounter those errors, your system fails to boot further resulting in the complete inaccessibility of your precious data in the drive. In a Linux system, there are many types of boot errors which may put you in trouble, one of them may be read as below:
"Creating Root Device
mounting root filesystem
(scsi:0:0:0:0) CRC error during data-in phase
(scsi:0:0:0:0) CRC error in intermediate CRC packet
scsi: aborting command due to timeout: pid 0, scsi 0, channel 0, id 0, lun 0 read (10)......"
Once, you encounter the above error, the booting process of your Linux system halts infinitely and all your data becomes inaccessible till you resolve the issue.
Causes:
From the above error message, many users mistakenly think that there is certain hardware related problem, however, following are some of the reasons that are actually responsible for the problem:
Possible corruption or missing of /boot directory from the Linux installation files.
Possible file system corruption.
Damage or missing of the 'initrd' file.
Note: The directory '/boot' stores critical information about the booting process and the parameters. Similarly, the 'initrd' file is a root file system that is mounted before the real file system gets available to the operating system.
Resolution:
The best possible way to resolve the above issue is to run the installation disk of Linux and try to restore the damaged/missing '/boot' directory and/or 'initrd' file. In case, you failed to resolve the issues by the above method, you have to retrieve the data from a valid backup. However, if a valid backup is unavailable or due to any reason, you failed to restore data from the backup, then you have to take the help of any third-party Linux recovery application.
