RAID ADG Data Recovery
We recover your data professionally and are very experienced in restoring Hewlett Packard ADG RAID arrays.

RAID ADG Recovery

Attingo is able to reconstruct your lost data from RAID ADG (Advanced Data Guarding. This is an implementation for RAID 6 by Hewlett Packard and Compaq AG. It is often used with Compaq Smart Arrays, where the parity is calculated via complex Galois polynomials.

Data rescue from RAID ADG systems

  • Two or more hard drives break down. Attingo will extract the data in the in-house clean room laboratory and reconstruct the virtual drive. 
  • Data loss often happens due to errors inside the RAID controller (BIOS, software). Attingo is able to recontruct the lost data.
  • After a firmware update data may be lost because of a changed storage order.
  • Attingo recovers the data if the RAID ADG is degraded or offline.

Capacity of a RAID ADG

The sum of all hard drives minus two.

RAID ADG pros and cons

  • In the worst case two or more hard drives break down. The array is no longer accesible and a data rescue is needed.
  • In the best case only one or two hard drives break down. The system is still working and there is no data loss.
  • To perform a successful data rescue, the so-called "generator syndrome" as well as the distribution of the input and parity blocks are necessary.

Hat alles super geklappt und wie besprochen
2016-07-06: , Seagate 3TB Constellation CS SED ST3000NC000 aus QNAP TS-1270U-RP | RAID6 | Linux | EXT

Leistung ist super, Preise sind halt in der Datenrettungbranche extrem hoch.

Waren mit Service sehr zufrieden
2012-03-28: , Seagate Barracuda ES.2 ST3500320NS aus Thecus N7700 | Linux | NTFS

hab von Branchenkollegen auch nur Gutes über euch gehört

Alles wunderbar funktioniert
2011-03-02: , Seagate Barracuda ES.2 aus Open-E NAS RAID | RAID6 | Linux | Unix

Hätte es natürlich gern günstiger gehabt, aber Sie waren immerhin halb so teuer wie K****.
