RAID 1 Recovery
We recover your data professionally and are very experiences in restoring data from RAID 1 arrays.

RAID 1 Recovery

In most cases it is possible to recover data from a defective RAID 1. Thanks to its redundancy a RAID 1 provides high failure safety. Nevertheless, RAID 1 breakdowns occur again and again. Our highly qualified technicians and engineers are specialized in recovering data from defective RAID systems. They recover data from RAID 1 systems with a success rate of over 98% percent.

RAID 1 recovery - causes for data loss

Defective RAID controller

If the RAID controller is damage, the data is no longer accessible. Possible causes can be physical damage as well as errors in the BIOS or the software. Firmware upadtes may also induce data loss. Exchanging the defective hard drive with a structually identical one often does not help, because of individual configuration parameters on the defective controller. Nevertheless, the chances for a successful data rescue from a RAID 1 are high! 

Files were deleted by accident

If files are deleted by accident, the data on all the hard drives in the RAID 1 were erased in the dame way. Under the right circumstances those files can still be recovered.

One defective hard drive in the RAID was not detected before

It often happens that one hard drive breaks down unnoticed - the redundancy is gone. This is detected as late as the second hard drive breaks down. As a result, there is different data content on the various hard drives. Therefore you should send us all the hard drives for the data rescue!

Defective file system, update errors

Defective file systems can also cause data loss from RAID 1 systems as well as firmware updates and bugs (especially on NAS systems).

Attingo is rescueing your data already during the diagnosis and analysis

After the diagnosis is finished within a few weekdays you receive a fixed price offer and a list of saved data. In urgent cases that process can be sped up significantly. Our specialists will be working on your case all around the clock, even on weekends and holidays. We'll be happy to advise you on our different diagnosis options.

Your RAID 1 does not leave the country

We take care of your device from the pick-up to the delivery of your rescued data. Defective hard drives will neither be sent abroad nor to third-party providers. Diagnosis, analysis and the data rescue itself will be solely performed in our in-house clean rooms.

How to act in case of data loss from a RAID 1

  • It's very important that you remain calm. Even if there have been rescue attempts, a successful recovery is not impossible.
  • Tell us the hard drive model used in the RAID 1.
  • What kind of device is it (NAS, DAS, ...)?
  • Tell us the RAID 1 controller model (or rather the type of mainboard, if the RAID 0 controller is operted onboard). This information may speed up the data recovery process.
  • Do not install or initialise anything on the system anymore.
  • Do not restart or rebuild the RAID 1  to prevent consequential data loss.
  • Label all the hard drives with their slot number and mark the defective ones.
