With years of experience in the data recovery field and qualified technicians working around the clock,we have the technical expertise to handle complex RAID recoveries.

It is easy to recover data from windows, but we can successfully recvoer data from complex Virtual Machines.

When your RAID fails, do not attempt to repair or rebuild your RAID array. If done incorrectly or with the wrong stripe block size or disk order, this may corrupt your data permanently. Don't risk it!

Different Levels of RAID

RAID 0 - Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.

RAID 1 - Mirroring Volume: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.

RAID JBOD 1
RAID 5 - Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.
RAID 10 (or RAID 0+1) - A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.
Data recovery process becomes much more complicated when dealing with a failed hard drive which is part of a RAID array, and this is why it is important for professional, experienced data recovery specialists to handle the recovery.

How to recover RAID ?

We provide extensive RAID recovery services. The safe and proper way is to image all the drives of the RAID array first, then work on those images to rebuilt the data. We often need to repair one or more drives from electronic or mechanical failure first then image afterwards.

In theory, we should not have to perform RAID5 data recovery since this type of RAID can work in degraded mode until you replace the bad drive, then everything is back to normal once the RAID 5 rebuilds itself.

The most common mistake with RAID 5 is when a good disk is replaced instead of the bad one. An immediate failure occurs since most RAID systems can’t work with 2 disks that are faulty. The same problem occurs if the user specifies a wrong number of disks while rebulding the failed RAID. This often happens due to the use of a hot spare which is not, in theory part of the raid itself.

On the other hand, RAID0 recovery is common, since this type of RAID offers no tolerance to failure. If any of the drive crach or fail, then your data is gone. We perform a lot of RAID recovery on RAID 0.

Please note

There is only one case where we can’t recover data. If a RAID is reinitiliazed (which takes hours), all data will be lost. It will basically write 0 over the entire disks. There will be no data left to be recovered.
