What is your success rate for recovering RAID data?
      How does MicroCom stack up against the competition?

Our Answer:

Actually, the answer to this question has some complexities to it — the short answer is that MicroCom recovers about 94 percent of all the cases we work on.

There are numerous contingencies that determine the recoverability of data from a RAID subsystem.  First, in regard to the collective array of hard drives, i.e., the data storage subsystem we normally just call "the RAID", the essential thing is that no more than one stripe segment of a RAID-5 stripe array sequence (or no more than two stripe segments of a RAID-6 stripe array sequence) turns out to be unobtainable.  By the same token, with RAID-0, all stripe segments must be obtainable, and also, all array member hard disks drives must be recoverable.

Then, when it comes to any failed individual RAID storage element, there are fundamentally only two things that make data upon any given hard disk drive array member unrecoverable.  For the individual disk drive elements these are: (1) the medium upon which stored data was recorded has become damaged, or (2) the data needed from a particular array member drive was over-written with newer information that eradicated the original data; this kind of thing is a frequent outcome of failed rebuild attempt. NO ONE can recover data in either of these cases.

We are confident in saying that our recovery expertise can recover data from electronic data storage media in well over 99% of cases where it's possible for the data to be recovered by anyone in the commercial field. Over the twenty years that MicroCom has been recovering data (since 1989), our resident expert and chief engineer, has on several documented occasions, recovered data from damaged RAIDs after famous competitors had failed or declared that retrieval was not feasible.
