Recovering data from hard drives that use the XFS file system

Data Recovery XFS Filesystem

The XFS file system is a Linux derivative that is increasingly popular in many Network Attached Storage (NAS) arrays. The chances are that if you are running a NAS device, then it will be using the XFS file system. Most NAS systems will either be running as a RAID 0, RAID 1, or RAID 5.

Example NAS manufacturers whose equipment uses XFS

  • Buffalo
  • LaCie
  • DLink
  • Western Digital
  • Seagate
  • + many others !

These NAS devices all use standard hard disks from the usual manufacturers and as such, these devices are prone to all the usual types of hard disk faults and failures. If your NAS box has developed a fault, we recommend that you check through this list first and try to identify the problem. If your NAS device is working fine and your problem is to do with deleted data then please read on!

Recovering deleted / lost / inaccessible data from XFS

The XFS file system is fast, compact and efficient. Because it is based around iNodes and Superblocks, recovering data that has been deleted, or data where the related iNode / Superblock information has been damaged or overwritten will prove rather problematic for nearly all data recovery companies. As part of our Advanced Data Recovery programme we have developed some XFS mapping tools that are often able to recover deleted data by producing a work around to damaged / deleted / overwritten Superblocks and iNodes.

We have had success with these tools and have recovered data from RAID systems where other data recovery companies have failed.

If you have an XFS system with deleted data, we would certainly be interested in taking a look at it. Call us on 0800 151 2207 to discuss.
