Linux Can Make Data Recovery Complex - But Not Impossible

Linux, like its big brother UNIX, comes in different flavours. SuSE, Novell\SuSE, Red Hat, Debian, Mandrake and Gentoo are among the most common types and we also work on home made versions of the Linux operating system from time to time.

Linux presents some special challenges when it comes to data recovery. Its single hierarchal structure starts from the root directory and expands into sub-directories. Linux places partitions under the root directory by mounting them under specific directories. Therefore, unless a partition or device is mounted Linux will not know that it actually exists. While this method of operation provides versatile management of logical and physical drives as mount points, it requires a rare level of expertise when it comes to data recovery. In-depth knowledge and understanding of the EXT2 and EXT3 file systems is essential to effectively access lost data and ensure a successful recovery.

Do not attempt a repair yourself if you suspect an impending drive failure on your Linux operating system. The unskilled opening of any hard drive or RAID system will almost certainly damage your data further and dramatically reduces your chances of a successful recovery. Similarly, avoid off the shelf Linux data recovery applications. If you only have one chance to rescue your data make sure it's a good one - performed in the right environment by experts.

Similarly, rebooting or mounting a file system as a drive's lifespan rapidly reduces can compound problems and cause irreversible damage to the hard drive and any data stored on it.

Data recovery from Linux File Systems

Linux file systems and disk configurations also present their own unique intricacies. If you don't know how your file system is constructed, we can normally get a good idea of the underlying problem from your operating system once we have inspected your drive. Data Detect is experienced in recovering data from a range of GNU file systems including: Ext2FS, Ext3, Reiser, IBM JFS (Journaled File System) and XFS.

If you experience a hard drive crash or RAID failure on your Linux system, or your hard drive is making any abnormal buzzing or clicking sounds, (a good indication that it's about to sustain physical failure), you should power down the drive and remove it immediately. You can then contact us for advice, safe in the knowledge that the damage will not get any worse.
