Data rescue of server and Raid systems

Raid storage systems are offered by the manufacturers as being an especially safe method of mass storage. From our daily experience with defect Raid systems we know that fault repair with these systems is by far the main source for wrong decisions.

Raid systems react especially sensitive to the failure of more than one disk. Due to the architecture of these systems very often harmless errors are amplified and grow to be a chain of fatal events. Moreover, Raid systems are implied to possess inherent data rescue mechanisms. While in some cases this may be correct, users tend to undertake steps from an erroneous feeling of security which may finally prove disastrous.

In more than 80 percent of all cases to which Attingo is called for help the damage was done or amplified by well-meant rescue attempts by engineers without specialized knowledge.

Over many years Attingo Data Rescue has developed the hardware-based procedure Attingo AdvancedRaidResolver (AARR). It enables a complete analysis and step-by-step retraction of the entire Raid system by reverse engineering techniques by using algorithms specially adapted for every type of system and every configuration possible.

In emergency cases Attingo is available 24/7 with our entire highly qualified staff and our clean-room lab located in Vienna. The consequences of Raid failures are our special field of expertise which is at your disposal!

Common causes for errors and faults of Raid systems:
Defects of hard disks which may appear only during rebuild or as direct consequence of it
Damaged or faulty controllers
Inadequate support by manufacturers, eg when advised to rebuild the Raid5, delete or recreate it for lack of other options
Inadequate user documentation in error cases
User errors (disks are exchanges intentionally; more than one disks is replaces; all available options in the controller bios applied)
