Linux Data Recovery

Linux data recovery is now becoming more common in our lab. Ten years ago we would rarely see Linux outside of server machines, but now we often see home user and business laptops with Ubuntu, Fedora or Red Hat installed.

Linux Data Recovery – Similarities.

The hardware we use for Linux data recovery is exactly the same as it is for Mac and Windows recovery. Generally we first need to gain access to the hard drive on a low level, it doesn’t matter if it was used on Linux, Mac, Windows or whatever.

Differences.

Once we overcome the hard drive fault and have an exact copy of the drive, we will then use the Linux operating system to recover the data at file level. The most common Linux partitions we see are ext2, ext3 & ext4 but may also see ReiserFS, UFS & XFS.

Linux often uses a more complicated partition layout than Windows or Mac drives, with separate partitions for boot, swap and home folders. This doesn’t cause any problems, but needs to be taken into account.

Linux is often used by specialists in a particular field, so rather than Word files and Excel spreadsheets the data may be medical imaging files, source code, music / video production files.

It is quite common to see Linux machines set up with a RAID array. We can recover data from RAID systems, and have specialist tools to handle the recovery of RAID even without the original controller. Contact us for RAID costing.

When a hard drive fails you may see any of these messages

  • GRUB Loading Stage1.5 / GRUB Loading… / Error 17
  • Computer rebooting repeatedly
  • Computer stuck at splash screen / logo
  • SMART failure predicted
  • Primary hard disk error

Also listen out for any clicking, ticking or grinding sounds. These can indicate a physical hard drive problem which could get a lot worse if you continue to power the drive.

We can recover data from hard drives that have failed from

  • Electronic damage
  • Water / fire damage
  • Drops / falls
  • Firmware faults
  • Component failure / deterioration
  • Deleted files

If the data is still there, we can recover it!
