RAID 5 Data Recovery
Due to the high cost-benefit function, RAID 5 is currently the most frequently used RAID system. The surplus of a RAID 5 array is mostly limited to the possible failure of one hard disk. However, if for some reason another disk fails, the entire RAID volume is no longer available and may be "lost".
The experts at Gefund-IT are very familiar with the scenarios of RAID 5 data loss. Especially for standardised NAS systems of the RAID 5 configuration, you will benefit from our enormous performance capacity in view of the recovery time and cost factors involved in rescuing your data.
RAID 5: performance + parity
RAID 5 offers both increased data throughput when reading data and redundancy at relatively low cost, making it a very popular RAID variant. RAID 5 is one of the most cost-effective ways to store data redundantly on multiple hard drives while making efficient use of storage volume. However, due to high controller requirements and prices, this advantage often only comes into play with more than four disks. The usable total capacity is calculated from the formula (number of disks - 1) × (capacity of the disk). After failure of one hard disk or during the rebuild to the hot spare disk (or after replacement of the defective hard disk), the performance decreases significantly.
Data recovery from proprietary RAID formats
Some manufacturers of storage and NAS systems have developed customer-friendly and efficient RAID configurations, which, however, have a slightly different structure with regard to standardized RAID levels. What is convenient and practical for the user can become a particular challenge in case of data loss. Due to many years of experience, Gefund-IT is very familiar with most manufacturer-specific RAID systems and their professional recovery.
Some examples of manufacturer-specific RAID configurations are:
- Drobo BeyondRAID Technology
- LaCie SimplyRAID
- QNAP RAID
- Snap Server Dynamic RAID
- Synology Hybrid RAID
- Western Digital MyCloud
Which data do we save?
- Failure of individual hard disks, e.g. due to overheating in the server, mechanical damage during transport, voltage peaks due to faults in the electrical system or after a lightning strike
- Data formats of all operating systems like MacOS, Windows, Linux, DOS, etc.
- Data recovery on virtual systems like Hyper-V or VMware
- Faulty recovery; initialized and performed by the RAID controller
- Error message: RAID Offline/ Critical
- Error message: RAID degraded
- Corrupt database files like SQL, MySQL, PostgreSQL, Dbase, Oracle, Filemaker, Access, MS Exchange
- RAID group accidentally disbanded: mostly due to faulty administration
- All file types such as images, office documents, videos, databases, CAD drawings
- Typical RAID error messages

There are many ways to configure a RAID array or RAID storage server. If you are working with a Failed RAID array, you need to be careful how you handle it.
What usually happens is that a drive fails, but nobody will notice because the data is still available. Then at some point another drive fails and the data is no longer available. In a panic, the person responsible for the data storage tries to get the RAID online, but in the panic they start moving drives to force the RAID to rebuild or replace hard drives to get the RAID running again. Any of these procedures can lead to data corruption and complicate recovery.
So if you have a problem with the following RAID systems, call Gefund-IT Data Recovery immediately at 0791-49 39 04 98 and we will get your data back!
