Data Recovery For Linux OS

Linux is in fact, a member of the large UNIX family. Due to its popularity, low cost and open support, it has commanded a special niche in the operating system platform. Linux has been a very stable, flexible, secure and increasingly powerful OS with relatively low licensing fee. It is an OS much favoured by increasing number of technical users, each may choose to use a different flavour of Linux variants, amongst the more popular one, are :

• RedHat Linux
• Caldera Linux
• Mandrake Linux
• Turbo Linux
• SuSE Linux
• SCO Linux
• Debian Linux
• Slackware Linux

The file systems adopted are :

• ext2fs
• ext3fs
• ReiserFS
• JFS

Besides common hard disk crashes associated with desktop or laptop , one may encounter any of the following problems with the risk of losing the data :

• Damaged Super Block or Inode List
• Corrupted LVM logical volume
• Accident deletion (frequently through the command "rm")
• Reformatted volume
• Lost or damaged partitions
• Unable to mount volume
• Fail to perform fsck due to fatal errors

We find that a lot of Linux recovery jobs indicate problems associated with complete or partial hard disk failure and bad sectors. Under those circumstances, it is not advisable for users to run fsck or commercial utility as such intensive scan may result in further deterioration of media or file system.
