![]() ![]() DataTech LabsĀ® Experience with Buffalo RAID Data Recovery Protect yourself by making sure the professionals working on your Buffalo RAID systems have the right equipment and knowledge. 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. 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. 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. Recovery labs also have difficulty with Buffalo NAS units when files are deleted. 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. 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. Especially true with RAID arrays if the array stripe is damaged or out of alignment, this can cause severe damage. This can cause damage or loss of your data. 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. We do not recommend the use of commercial tools on these devices. Unfortunately, there limited commercial tools that will read XFS. XFS, is a high performance file system found on all Buffalo RAID Arrays. What to do when your Buffalo RAID system fails ![]()
