Ext2, ext3 and ReiserFS file are important file system of Linux. Ext3 and ReiserFS are journaling file systems and ext2 doesn’t support it. Thus for ext2, there is no automatic method that it may recover after power failure. With the help of Linux data recovery tools you can recover ext2 files.
Ext3 and ReiserFS run fsck after they have been mounted a certain number of times, which is restricted to 20-30 mount counts by default. In some cases, user may not wish to continue with the process because of the time it takes. Thus in such situations, the fsck check can be turned off. However the same method 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 harm 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 age in ext3.
On the other hand to disable the check, we need to make sure that ext3 entry in /etc/fstab possesses positive integer in 6th field. This is necessary 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 necessary 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 recovery application 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 simply 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 situation .Stellar Phoenix Linux data recovery software demo version is free in which you can see the preview of your recoverable file.
