Superblock Corruption leads to Data Loss in External Mac hard Drive
External USB is easily supported by Mac OS X and in this FireWire is present to store entire data, create the backup and even install operating system. The stored data in external hard drive can easily be used by attaching and mounting them. But in some situation this external hard drive becomes unable to be mounted by Mac OS X computer. This mainly happens when the data is transferred or accessed from the drive.
This behavior in Mac results in the inaccessibility of data and even data loss situation. So it is important to have updated backup available and in case the backup is not available then the data recovery becomes important. When the Mac OS X external hard drive becomes unmounted automatically then no noise is heard. This indicates that the hard drive is correct and is in working state. After this when the external hard drive gets attached to the Mac OS X then user may come across error messages like:
“Unknown device”
OR
“Mount: wrong FS type, bad option, bad superblock on /dev/hdb1,
Missing codepage or other error
In some cases useful info is found in syslog- try dmesg tail or so"
These errors are generally caused due to corruption in the file system, superblock corruption, damaged or missing system files. In this corruption can be caused due to many reasons such as improper system shutdown, virus infection, system malfunctioning.
In this situation there only left two choice for its users they can either choose to initialize their Mac OS X hard Drive or cancel the process. The only result that is left is data inaccessibility. So to resolve the Superblock corruption, it is important to perform Mac data recovery.
Resolution of Superblock corruption:
To sort out this behavior of Mac OS X operating system it is important to replace those data that are damaged. This can be done by formatting the hard drive and then reinstalling the operating system again. By this entire corruption and error problem gets resolved but at the same time the need for data recovery arises as such after formatting the data entire data gets deleted.
In this regard user can use third party software known as Mac Hard Drive Recovery software. This software has powerful algorithm that perform advanced scanning of the hard drive and results in the recovery of the lost Mac data safely. Not only is this but this software has read only features that does not hamper the original data.
