Ext2, ext3 and ReiserFS file systems are the three most popular Linux file systems. While ext3 and ReiserFS are journaling file systems, ext2 doesn’t support it. Thus for ext2, there is no automatic provision that it may rebuild after power failure. That’s the reason why Linux Data Recovery tools are more frequently required for ext2 file system.
Ext3 and ReiserFS run fsck after they have been mounted a certain number of times, which is limited to 20-30 mount counts by default. In few cases, user may not wish to continue with the process because of the time it takes. Thus in such cases, the fsck check can be turned off. However the same procedure is not recommended for ReiserFS. For journaling file systems such as ext3, disabling long boot time checks are tested and are considered safe. On the other hand, disabling it for ReiserFS may damage it. Ext3 and ReiserFS can easily return to the consistent state by replaying journaled transactions. But disabling these time dependent checks of fsck is only safe in ext3.
However to disable the check, we need to ensure that ext3 entry in /etc/fstab possesses positive integer in 6th field. This is required for automatic boot time check. We can make use of tune2fs command to disable the check by setting its maximum count to 0 and using it with –c options as:
# tune2fs -c 0 -i 0 /dev/hdXY
After this manual checks are required to retain fie system consistency. File system corruption eventually results as data inaccessibility. So, format operations are generally required if we don’t have any bootable media with which we can recover data. The data backup is vital to restore lost information. But, if no valid backup exists, Linux Data Recovery applications can be used to recover and restore lost information. So if it’s not possible, we can opt for simply limiting the checks through count or time frame. But if user is attempting similar process for ReiserFS, file system can easily get damaged.
Linux Recovery software can be used in any case of file system corruption. These graphically rich applications are easily available as Data Recovery Linux tools. The software can recover data in all logical data loss instances.
Stellar Phoenix Linux Data Recovery scans, recovers and restores lost data using the most powerful scanning algorithms. It can be used with ext2, ext3 and ReiserFS file systems. This Data Recovery Linux software is an advanced yet read-only utility. This Linux Data Recovery software has been designed using advanced techniques to logically recover lost data. It is made for Windows with the Linux hard drive as slave or external drive. It supports Windows Vista, XP, 2003 and 2000.
