RECOVERY SERVICES FROM HARD DISKS IN RAID

DATA RECOVERY SERVICES FROM HARD DISKS IN RAID

Do you need RAID 0 DATA RECOVERY or RAID 5 DATA RECOVERY?
We are experienced and have the necessary equipments for these procedures !

Any server or more complex application uses a RAID configuration intended to insure redundancy in case one of the hard disks fails.

In the vast majority of cases solutions such as RAID 1, 5,6,10 or 50 are used. These solutions share information from several hard drives in order to protect the data in case of unforeseen events.

Regardless of these safety systems offered by the RAID matrix there are also exceptional cases which will determine you to use to our RAID DATA RECOVERY services.

RAID SERVER defect

Regardless if the hard drive used in RAID are SATA or SCSI we can offer you RAID RECOVERY solutions.  We also insure recovery services for RAID HARDWARE or RAID SOFTWARE.

The most frequent cases requiring RAID DATA RECOVERY are RAID 0 matrixes or RAID 5. Here are some frequent RAID RECOVERY cases :

  • The server was configured with 3 disks in RAID 5 and two of them crashed as a consequence of power fluctuations
  • The controller no longer recognises the RAID or the hard drives and in case of the rebuild of the matrix on the same controller, you will probably lose the data
  • RAID controller fails and the data must be recovered from a RAID 0,5, or 6
  • RAID appears as corrupt and the controller can no longer repair it
  • RAID appears as corrupt and the controller can no longer repair it
  • RAID 0 was configured and one of the hdd crashes and the defective hdd must be recovered and then the matrix rebuilt for data recovery

There are many such unpleasant situations you can be confronted with even if you have a RAID configured which would insure the necessary redundancy.  For such cases we bring you professional recovery solutions based on years of experience in the field.

If you have a raid which requires data recovery, please contact us! One of our technicians will diagnose the RAID and you will then be informed on your chances of recovering the data as well as the recovery of costs. For any details concerning the shipment access our shipment page.

HARD DISKS IN RAID

THE MOST FREQUENTLY USED TYPES OF RAID

 RAID 0RAID 0 - This type of raid is very used for the performance of a virtual hard drive from two hard drives. That is, if you have two hdd of 500 GB and want to put them into RAID 0 you will get a virtual hdd of 1 TB. The advantage of this type of RAID is speed because a file is split automatically to the two hard drives.  The disadvantage is that if one of the disks fail, the recovery of the data is only possible by remedying the problem of the defective hard.  In case the defective hard disk cannot be remedied, there is no way to recover the data.

 Raid 1RAID 1 -Mirroring-is one of the most secure types of RAID, practically all the information is written to two hard drives at the same time. The advantage of this type of raid is clearly safety, in case a hdd fails there is the second hard drive containing the same information. The disadvantage is the fact that it is slower, since it writes the same data twice and limits the number of hard disks to maximum 2. In 98% of cases the recovery of the data is not necessary if one of the hard disks fail. The only situations requiring the recovery of data are human errors, practically if the user accidentally deletes data; it is deleted from both hard drives.

Raid 5RAID 5 - At present the most frequently used servers are RAID 5, the advantage of this type of RAID consists of the fact that it can be formatted into many hdds, at least 3 and maximum according to the RAID controller capacity. This type of RAID most often does not require HARDWARE encoding. Another advantage of this type of raid consists of the small space used on a hard drive to insure redundancy. Practically in case a hdd crashes the system keeps on working based on the other functional hard disks. The disadvantage of this type of RAID is the speed which can be relatively low because the controller must encode all the data to insure redundancy. Usually it is necessary to recover the data from these RIDS if they are corrupt.
