SERVICES OF DATA RECOVERY FROM HDD IN RAID CONFIGURATION 0, 5, 6, 10

CORRUPT RAID CONFIGURATION? BIT Data Recovery can help you recover you data!

Any server or more complex application uses a RAID configuration meant to ensure redundancy in case one of the hard drives fails.

In most cases, there are used such solutions as RAID 1, 5, 6, 10 or 50. These solutions distribute the information on several hard drives in order to ensure the redundancy in case unexpected events occur.

These solutions are safe in 85% of the cases, the remaining 15% are cases that cannot be solved just with the help of a specialist in data recovery:

• the server was configured with 3 hard drives in RAID and two hard drives failed over a one week interval and the RAID cannot be rebuilt unless there is a minimum of 2 hard drives
• the mainboard of the server fails and another one, identical to the first, cannot be found
• the RAID configuration appears to be corrupt and the controller can no longer fix it
• I set up a RAID 0 configuration and one of the hard drives failed
• I have a RAID 1 configuration and I accidentally formatted a partition

There are many unpleasant situations you may have to face, even if you have a RAID configuration to ensure the required redundancy. For such cases, we are at your disposal with professional data recovery solutions based on our technician’s experience.

If you have a RAID configuration that requires data recovery, please contact us! One of our technicians will diagnose the problem and tell you what the odds are for data recovery from your RAID configuration.

RAID 0 - This type of RAID configuration is used to create a virtual hard drive made up of two hard drives. That means if you have two 500 GB hard drives and you set them up in RAID 0, you will get a 1 TB virtual hard drive. The advantage of this type of RAID configuration is the speed, as a file is automatically divided between the two hard drives. The disadvantage is that if it happens for one of the hard drives to fail, data recovery can only be performed by fixing the problem on the defective hard drive. In case the defective hard drive cannot be repaired, there is no other way to recover the data.

RAID 1 - Mirroring is one of the safest types of RAID configurations; basically, all information is written at the same time on two hard drives. The advantage of this type of RAID configuration is obviously its safety; in case one hard drive fails, there is a second one containing the exact same information. The disadvantage lies in its lower speed as it writes the same data twice and limits the number of hard drives to maximum 2. In 98% of the cases, data recovery is not necessary, unless one of the hard drives fails. The only situations calling for data recovery are those involving human errors; basically, if the user accidentally deletes any data, it is automatically deleted from both hard drives.

RAID 5 - Currently, most servers use RAID 5, the advantage of this type of RAID being the fact that it can be made up of several hard drives, minimum 3, while the maximum number depends on the capacity of the RAID controller. Most frequently, this type of RAID requires HARWARE encoding. Another advantage of this type of RAID constitutes the reduced space used from a hard drive to ensure the redundancy. Practically, in case a hard drive fails, the system remains operational based on the other operational hard drives. The disadvantage of this type of RAID is the speed which can be fairly low due to the fact that the controller needs to encode all the data in order to ensure the redundancy. Usually, it is necessary to recover the data from such RAID configurations if they become corrupt.
