  • Raid Data Recovery

With extensive experience in the field of data recovery, Stellar has all the required technical expertise that ensures secure RAID Recovery solutions for simple RAID configuration (RAID 0, RAID 1, RAID 5) to more complex configurations (RAID 50, RAID 6, RAID 6EE etc.) used inside any server or huge Data storage boxes (NAS, SAN).

With in-house Research & Development comprising of software & hardware engineers, team of RAID recovery experts, state of the art infrastructure of ISO CLASS 100 Clean Room, Stellar can recover data lost due to any logical or physical data loss situation.

Situations of data loss and their causes in different RAID level:

There are multiple situations that causes data loss from RAID Systems such as;

  • RAID Array Failure
  • RAID controller failure
  • Server Not Booting
  • Rebuild Failure
  • Damaged Strip
  • Hardware Failure
  • Volume/ Partition not found
  • RAID configuration corrupted or overwritten
  • Software Corruption or Software/ Operating System Upgradation.

In RAID 5 or above, if you lose one disk in the array, still you can rebuild all the information by replacing the damaged drive. However, if you have situation of multiple disk failure at the same time or the rebuilding exercise stops in between, then it is a complex RAID failure and the smallest mistake can cost you your whole data.

How Stellar can help you to recover your data from Raid?

For any data loss situations, if valid backup is not available, Stellar RAID data recovery service is the safest option for getting your business critical data back. Stellar has advanced tools & technologies and in-depth knowledge of how the data is managed in different RAID configurations that delivers unmatched RAID recovery results.

Dos & Don'ts Related to RAID Failure

  • Always label the drives with their positions in a RAID array.
  • Never try any repair utilities on inaccessible volume/ drives.
  • Never run any defragment utilizes without knowing the health status of individual drives.
  • While replacing the faulty drive, always ensure that the new drive is zero filled and has =< number of sectors of the faulty drive
  • Always ensure good health of all the individual drive attached in the RAID array, before rebuilding.
  • Never try rebuild if more than one drive fails/ is offline.
