HP UNIX Recovery After “Can’t Read Superblock” Error
With HP-UX UNIX, after situations like operating system reinstallation, hard drive formatting or unforeseen data loss, when you try to restore data from disk image, it may not mount. So, the data can not be accessed from it. It results as critical data loss and requires HP UNIX Data Recovery to be fixed.
While mounting the disk image to restore data from it using “mount /dev/sda1/image name” command, you receive the following error message:
“Mount: /dev/sd1: can’t read superblock”
This behavior of your HP-UX UNIX computer makes all your valuable data inaccessible and causes serious data loss.

This problem generally occurs either due to Superblock corruption or Partition Table corruption. In both of these situations, data loss may take place.
Superblock is a critical HP-UX UNIX data structure that keeps record of file system characteristics such as its size, block size, filled and empty blocks and their relevant counts, location and size of inode tables, disk block map and its usage information and size of block groups. A request for accessing the file needs access to superblock. If it can not be accessed, the file system can’t be mounted and the file becomes inaccessible. Any attempt for mounting the file system with corrupted superblock would likely fail.
Partition Table is a reserved area of HP-UX UNIX hard drive that stores partition/volume information. The hard drive is divided into at least one and at most four primary partitions/volumes. All these partitions/volumes are described by 16-bit entries which constitute the partition table which is located in MBR (Master Boot Record). When it gets corrupt, the partition/volume entries are deleted and thus the data stored on them becomes inaccessible.
In both of these situations, you need to opt for HP UNIX Recovery to salvage your significant data from logically damaged hard drives. It is best possible using HP UNIX Data Recovery software.
These software are specifically designed to methodically scan the affected HP-UX UNIX hard drive and extract as much data as possible from it. These software incorporate advanced and powerful scanning methods to achieve perfect results.
Due to read-only design and interactive user interface, using these software is completely safe as well as easy. In order to ensure complete HP UNIX Data Recovery, you should opt for powerful and power packed recovery tools.
Stellar Phoenix HP UNIX Data Recovery software is an efficient HP UNIX Data Recovery tool to get all your lost data back. The software supports recovery from JFS 3.0, 3.1 and 3.3 file system volumes of HP-UX 11i, 11 and 10.x.
