SCSI CRC Boot Errors May Cause Data Loss in Linux

By Allen Sood

Booting errors are very common in Linux operating system, which makes your system unbootable and unusable. The errors prevent your system from booting and render it totally inaccessible. They prove to be a big threat to your precious data. Such errors usually occur after unexpected system shutdown and hard drive data structure corruption.

Losing data from hard drive in such situations creates big problems for your business. So, you need to restore data from the latest backup to prevent data loss. However, in case backup is not updated or available, Linux Recovery solutions come to your help.

When you face boot errors, your Linux system refuses to boot properly. There are various types of boot errors, depending upon the type and cause of failure. One such error is SCSI CRC error. You may come across the below error message when your Linux operating system loads:

"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 above error halts Linux boot process, making your hard drive inaccessible. To retrieve lost data in such cases, identify the problem and perform Data Recovery Linux by resolving it.

Cause

On the first appearance, this issue seems to be associated with hardware problems, but this is not the case. You may face this behavior due to any of the below reasons:

• Damaged or missing /boot directory from Linux operating system installation.

• File system error or corruption.

• Missing or corrupted initrd.

/boot directory is a major component of Linux operating system, which contains critical information about booting parameters and process. While initrd is a temporary data structure, which makes preparations before mounting of root file system.

Resolution

Use Rescue CD of Linux operating system to overcome this problem by restoring damaged /boot directory and initrd. When it fails, go for Linux Data Recovery software to retrieve lost data.

The Linux Data Recovery applications are able to scan damaged Linux hard drive and extract all lost data from it. They have read-only conduct on the drive to ensure safe recovery, without modifying original data on the disk.

Stellar Phoenix Linux Data Recovery is the most comprehensive and advanced utility to ensures absolute recovery of lost data. The software works well with all major distributions of Linux operating systems, such as SUSE, Debian, Red Hat, Ubuntu, and Fedora. It recovers data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.
