The booting errors are dangerous threat to the data kept in any of the operating system including Linux. Once the system shuts downs unexpectedly the risk of crucial issues and data threatening problems is always there. The most probable instance is when the system refuses to boot properly with some sort of error messages. In Linux operating system in similar conditions the user is found to report having some SCSI CRC error messages like:
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) ......
The trouble appears to be related to the hardware issues but actually its not. The problem could be any of the following:
- File system faults
- Corruption in the /boot directory
- Damage of initrd
/boot is the repository of all the information that is requires at the booting time while the initrd is the temporary one which is used for making any preparations prior to the real mounting can be done through root filesystem.
You can use the Rescue CD to come up the situation and restore the /boot directory. You can also try out the cloning of the disk and its diagnosing. But when none of the solution is practical Linux recovery is the serious issue to be tackled.
Linux data recovery is compulsory when the hard drive is the bundle of all the important data required from many angles either from business or personal. Linux recovery software can do this job very well which are needed to be installed on any healthy system and the affected hard drive is attached to this system.
These data recovery Linux utilities have the power to scan the hard drive effectively with the powerful algorithms and to retrieve the information intact. Empowered with the interactive user interface, these Linux recovery tools don’t make any changes to the actual data.
