Contact ReWave toll-free at 866-739-2835 or click here to submit
a free price quote for RAID 0+1 data recovery.  We are available
24/7 for your RAID recovery needs.



A data recovery engineer will assist you with a free price quote
for recovery and instructions to receive the free evaluation to
determine if your data is recoverable. You can bring your RAID
drives to one of our recovery labs or
ship the drives to us using our
shipping instructions.



Upon receipt of your drives, a data recovery engineer will perform
the free evaluation.  You will be contacted with the results and
given the option to proceed with the recovery of your data.  The
actual recovery process will then begin. 




RAID 0+1 requires a minimum of four drives.  Additional drives must be added in even
numbers.  If four drives are used, a pair is first striped as in a RAID 0 and then is mirrored
as in RAID 1.  The total storage capacity is calculated by summing the storage capacity
of all the drives in the array and dividing it in half.   For this reason, RAID 0+1 can be very
expensive.  This level does offer increased performance over some of the other RAID levels
due to the striping that takes place.  Because there is a mirrored copy of the stripe set, a
RAID 0+1 array allows the failure of one or more drives as long as the failure of each occurs
in the same stripe set.  When this type of drive failure occurs, the RAID 0+1 essentially
becomes a RAID 0 and is vulnerable to drive failures in the mirrored copy.

A RAID 0+1 array is normally used in servers that demand high performance.  This type of
array is also used in high capacity external hard drives. For more information about devices
with built-in RAID 0+1 technology, click here.

The following diagram illustrates a RAID level 0+1 (a mirror of stripes).





There can be many reasons for RAID 0+1 failure.  Listed below are some of the most
  Bad Sectors on the disk Missing Partitions
  Corrupt Data in the array Overwritten Files
  Corrupt Files in the array Array Backup Failed
  Corrupt RAID 0+1 Controller Broken RAID
  Damaged Files on the disk RAID Controller Failure
  Deleted Files in the array RAID Crash
  Failed RAID 0+1 Server Crashed
  RAID 0+1 Drive Failure RAID Firmware Failure
  RAID Power Failure RAID Power Surge
  RAID Rebuild Failure RAID Will Not Boot
  RAID Disk Failure MFT Corruption




If you experience problems with your RAID 0+1 array, please do not attempt to correct the
problem yourself.   By taking matters into your own hands, you could overwrite parity data
making RAID recovery more difficult.  Please follow the steps below and contact ReWave
for assistance at 866-739-2835.

Turn off your RAID 0+1 device immediately.  This ensures that no additional data
can be written to the array, which could overwrite the data you are trying to recover. 

Document the events that occurred causing RAID 0+1 failure.  Try to make
notes documenting any problems that occurred and efforts that were made to fix the
problems.  If you remove the drives from the array, it is important to label the drives
with the same order in which they existed in the array. Although not required, this
step will save us time during the RAID recovery process.

Contact ReWave immediately.  Our data recovery team is available 24/7 to assist
you with RAID recovery at 866-739-2835.
