RAID Data RecoveryRAID Levels

RAID Data Recovery

Our  RAID data recovery engineers are trained to handle all of the current server hardware platforms as well as commonly used legacy systems utilized in the market today.

Complex fault-tolerant systems can also suffer from a crash. Often, failure to correctly implement these systems leads to point of malfunction and can cause data loss. This is human error and not shortcomings of the technology used or the design of the array.

Even the best-configured system can fail due to:

  • RAID Controller failure
  • Multiple drive failure
  • Accidental replacement of media components
  • Accidental reformatting of drives or whole RAID array
  • Array configuration lost
  • Intermittent drive failure resulting in RAID degradation

Northwest Data Recovery, LLC has extensive experience in recovery from failed RAID‘s, including parity-distributed and basic spanned or striped volumes. We only require the active members of the array in order to recover lost data – no controllers, cables or enclosures. If you are asked for the original RAID controller or array system by a data recovery company, be careful – you may be risking recoverable data to an inexperienced firm!

RAID Levels

RAID Levels with different architectures have a lot of similarity, but each type also has its own “favorite” failures and different techniques to handle too:

  • RAID 0 Data Recovery
  • RAID 1 Data Recovery
  • RAID 10 Data Recovery
  • RAID 5 (50) Data Recovery
  • RAID 6 (60) Data Recovery

Every single RAID data recovery   case which arrives at our labs receives high priority importance because we know and understand them to be a top priority for most organizations. Our disk recovery process, coupled with our ability to produce a safe sector-to sector dump of the complete volume, allows us to process an array as a collection of image files. RAID recovery  of crashed members of the array is similar to hard drive recovery procedures.

We are expert in all Disk Based Hardware and Software RAID Array Configurations:

  • RAID 0
  • RAID 1
  • RAID 0+1
  • RAID 1E
  • RAID 3
  • RAID 4
  • RAID 5
  • RAID 6
  • RAID 10
  • RAID 50
  • RAID 51
  • RAID 5E
  • RAID 5EE
  • RAID 7
  • RAID Z

All further procedures to recover data from array members are done on the raw images, leaving original drives intact. Our advanced software tools will extract the data from the images. When a drive image is not available, the tools can reconstruct the data ‘on-the-fly’ in the same way that the RAID rebuild process would have done on the original system.

After determining what steps will be necessary to complete your RAID data recovery, we will contact you for approval . No work will be done without your approval. As soon as you approve the quotation, our engineers will continue with the recovery process.

Frequently Asked Questions

Q. Can you recover data from our RAID if it isn’t broken?

A. Absolutely, we have recovered data from broken, decommissioned, and live RAID Arrays.  Functional & live recoveries take less time since the RAID doesn’t have to be reconstructed.

Q. Our RAID array is part of a storage area network (SAN) utilizing fiber channel, can you get our data?

A. We frequently recover data from corporate & public sector servers.  There has not been a server too large for us to get the data off of yet.  All we need is a place for our equipment to tie into your fabric and we can recover your data.  Care is taken to make sure we don’t saturate your core or impact your workforce.

Q. My business is down, how long does it take to recover a RAID array?

A. The amount of time it takes to reconstruct a RAID array is heavily influenced by how badly the array has been damaged, if there is physical damage to the disks, and the number of disks in the array.  Rest assured that each RAID recovery is performed without delay and in a manner which will not jeopardize your data.

Q. The disks were removed and I don’t know their original order, can the data still be recovered?

A. While it is helpful to know the original order of the disks, it is not necessary.  Once the disks are imaged we can inspect their contents and determine their order from the file fragments on the disks.

Do-it-yourself data recovery risks

Attempting data recovery yourself could permanently damage your hard disk, making data recovery more difficult and more expensive… if it the data can be retrieved at all

Sometimes, a RAID drive will fail and cascading failure of the array will follow very quickly. If more than one drive is damaged in a RAID 1 array, or more than two hard disk drives fail in a RAID 6 configuration, data loss will occur.
