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!

Common RAID Failures

RAID Drive Failure
RAID Controller Failure
RAID Array Corrupted

RAID Configuration Lost

RAID Degradation

What to do when RAID fails

Do not try to rebuild or reinitialize your RAID
Do not run FSCK on your RAID
Do not run CHKDSK on your RAID

Different Levels of RAID
Traditional 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.

可能是包含下列内容的图片：上面的文字是“DRAID Overview -Storage server- RAID2.0 Technique Traditional RAID (TRAID) has a very rigid layout: -RAID-10: N data drives N mirrors, spares -RAID-5/6: N data drives P checksum drive (RAID-6: P+Q). spares DRAID distributes blocks over any number of drives such that: -Spares are virtualised and distributed across drives -Host I0 is balanced across drives -Rebuilding a failed drive balances IO across all other drives DRAID keeps the same failure protection guarantees data blocks plus P (+Q) checksum) balanced over more physical drives DRAID recommendation is 40-80 physical drives (up to 128)”
