Data Rescue 24/7

Data loss: No need to panic!

Keep calm. Attingo data rescue will recover your lost data. Do not try to correct the damage on your own!

Data loss – what should you do?

In more than 90% of all cases, Attingo’s experts will be able to recover lost data. Impending data loss is definitely a state of emergency. Remaining calm and not performing rash steps will prevent that the damage becomes even more severe.
We would be happy to provide individual advice - Feel free to call us.
Or send us a non-binding request online.

For this, Attingo data rescue operates an in-house clean room laboratory. Our technicians and engineers have extensive knowledge and can perform the required procedures to perform both the physical as well as logical data rescue. Furthermore, Attingo data rescue has tens of thousands of hard disks from all manufacturers and production series stored as spare parts.

Data loss – what should you avoid doing at any cost?

Do not reboot! Turn off the computer.
In almost all cases of data loss, it is very important to turn off the system and not restart it again. This applies to PCs, Apple systems, servers, NAS units and also RAID arrays.

Hardware damage
Hardware damage is increased by powering the storage medium up again; surface damage is exacerbated. Clear signs of hardware damage of a hard disk are audible clacking, clicking, whirring or screeching noises.
In the same manner, voltage spikes and environmental influences are often the cause of lost data.

Software damage
Additionally, software damage such as the accidental deletion of files or directories, re-formatting, recovery installation or file system errors, have severe consequences in the case of a restart. With each activation or booting of a system, temporary files and paging files are generated. These could overwrite data system information essential for a data reconstruction or even data itself.

Bad advice
A great deal of bad advice can be found on the Internet that can have severe consequences: For instance the recommendation to store the affected storage medium in the freezer and then turning it on immediately. The consequences are among others short-circuits, misaligned write/read heads or no longer functional hard disk bearings.

Do not perform rescue attempts on hard disks
Hard disks may only be opened in dust-free environments! If a hard disk is not opened by a data rescue professional, then the damage will be worsened massively and the costs required for the data rescue will be considerably higher.



RAID is not safe!

Attingo’s technicians have been reconstructing server and RAID systems for more than 20 years. One thing is clear: RAID is not safe. Irrespective if it is a RAID1, RAID5, RAID6 or RAID DP system. Every day our engineers perform reconstructions of these systems that are deemed to be safe.

The simultaneous failure of several hard disks, an incorrectly configured monitoring or simple bugs in the RAID controller firmware can also cause data loss in RAID systems. In particular, in the case of the failure of a RAID system, the pressure experienced by the person responsible for IT is enormous: Such damage often results in an entire company or enterprise coming to a complete standstill. The understanding that a RAID system can fail is often not present.

This results in panic reactions: Hard disks are replaced, rebuilds are initiated and hard disks are forced to mount. In the worst case, the manufacturer’s support will recommend deleting the RAID configuration and creating it again from scratch – a fatal error (which unfortunately is actually regularly reported by our customers!).

An additional point, which exacerbates the damage in the case of a RAID failure are the so-called “fatal rebuilds”. These for instance occur when the sequence of the storage media in the RAID system no (longer) coincides with the slot numbers, a RAID array is forced to mount and a rebuild is started. As a result, in the worst case, data strips are overwritten on all hard disks.

Due to the fact that the data in RAID systems is not linear per each disk, but instead is written in blocks and distributed across all disks, such actions following a failure are often fatal.

You can find more detailed information on the topics described above under RAID data rescue.

In the case of the failure of a RAID system, contact Attingo data rescue – before you take any steps – and describe the problem you are experiencing to us. We would be happy to advise you.



How can I recognise a legitimate data rescue service?

  • If a company appears to be an inland company, however has an address located outside of the country, you should act with caution. Furthermore, when the legal form of the company is foreign, then it should be checked very carefully if it actually is a serious provider of data rescue services.
  • Complete company details with the name of the general manager as well as the registration number.
  • The company has its own national clean room. Many providers of data rescue services are only intermediaries and send the defective storage media to a partner abroad. Often they even only have a virtual office: This can be easily discovered when you perform an Internet search for the supposed address and instead find an “office rental” company.
  • It must be possible to personally hand in a storage medium or server at the laboratory.
  • Invoicing according to the data volume is dubious (for instance per gigabyte) because the costs for data rescue always depend on the work involved. For instance the reconstruction of a deleted video with a size of 450 GB is often less work than the recovery of a 25 KB Word document from a hard disk that was damaged in a flood.
  • There are numerous reports on Internet forums made by those that used the data rescue services. However, there are also many contributions that have been written by the service provider himself or from their competitors (similar to hotel comparison platforms and similar). Yet, when one is willing to invest some time, it is possible to make an evaluation of the integrity of data rescue service providers.
  • Diagnosis that is free and against a fee: In both cases the data rescue provider should exactly specify what the customer will receive in the case of a diagnosis that is free or requires payment. Often desperate customers are baited with free diagnosis services. However, as soon as the storage medium is at the data recovery service, the customer is practically blackmailed.
  • Certificates are not a 100% guarantee, yet they often can be an indicator for the integrity and professionalism of a data rescue service. However, again a verification with the party issuing the certificates should be performed.
  • Reports on the data rescue service in newspapers, magazines and other media, current press releases or the presence on trade shows are additional positive indications of their trustworthiness.
