What to do when your Buffalo RAID system fails
XFS, is a high performance file system found on all Buffalo RAID Arrays. Unfortunately, there limited commercial tools that will read XFS.
We do not recommend the use of commercial tools on these devices. These tools can sometimes help, but, because it is not specifically used for recovery, more often these tools fragment and overwrite data or simply destroy the file system structure. This can cause damage or loss of your data. Especially true with RAID arrays; if the array stripe is damaged or out of alignment, this can cause severe damage. Even if alignment is only off by a single sector out of every million, any commercial tool will create more damage and complicate the system recovery. There are procedural steps that must be taken before anything like this should ever be attempted and should only be attempted by a professional that is highly knowledgeable in UNIX.
Recovery labs also have difficulty with Buffalo NAS units when files are deleted. XFS, as a high performance file system, does not delete files in a way that leaves vestiges of the file in the same way that other file systems do. Consequentially, many data recovery companies wrongfully believe that deleted data is impossible to be recovered from these systems but will still ask for the job anyway. This could be due to lack of knowledge about the complexity of recovery or trickery in hoping to recover a few single lost RAW files and saying that is all that can be recovered. Protect yourself by making sure the professionals working on your Buffalo RAID systems have the right equipment and knowledge.
