Servers and desktop computers can extend their storage capabilities by using a RAID (Random Array of Inexpensive Disks) which is where a group of disks are configured to work together forming a RAID array, appearing as one large drive to the host computer or server.
There are many different combinations of RAID levels that can be employed depending on your storage requirements. Although each disk is susceptible to normal hard disk failures, some RAID levels can provide additional redundancy to prevent data loss, effectively giving you a second chance.
If more than one disk fails or the RAID configuration is corrupted, then the RAID array may be damaged and become inaccessible. It is important to be careful in this type of scenario. All the data in the RAID array could be lost if the disks are placed into the hands of an inexperienced data recovery company.
Damaged, corrupted or deleted RAID arrays can be recovered by a data recovery specialist who understands RAID levels with a thorough understanding of RAID data structures and file system architecture. If your RAID array fails, safely shut down the RAID unit or computer and speak to a RAID recovery specialist.
Do not take risks with your RAID data by sending the hard disks to an inexperienced data recovery company who may compromise the RAID array. Always speak to a data recovery specialist to confirm the RAID recovery process and procedures used to recover your data before sending the disks away.
One of the fundamental procedures, is to first secure the data, by imaging each RAID disk onto secure servers and only recover the data from the images. If a data recovery company does not have this basic understanding or RAID recovery capability, your data could be put at serious risk.
