Reconstruct and Rebuild Corrupt RAID Arrays for RAID Recovery

RAID reconstruction is a safe and effortless procedure to safely recover data from inaccessible or corrupt RAID hard drives without damaging data stored on original disks. In reconstruction, stored data will be salvaged from the original disks and saved into another disk of same or higher capacity.

RAID reconstruction requires you to recall certain RAID parameters and enter wherever required. Required RAID parameters are starting sector, drive order, block size, RAID rotation, etc. If you exactly remember these, you can immediately reconstruct data stored on RAID hard drives. Else, use RAID recovery software capable in automatically calculate the RAID parameters based on inputs taken and reconstruct RAID arrays which makes your RAID architecture accessible again.

Reasons of unsuccessful RAID reconstruction

There are various occasions when the RAID server become inaccessible and requires to reconstruct arrays. If you’ve provided incorrect RAID parameters while reconstruction process like wrong drive order, parity bit or block size, etc., it’ll result in failed reconstruction.

Don’t worry if the reconstruction fails, you can run it again. As the reconstruction operation is safe and doesn’t write anything to the original drives, unlike Rebuild operation, you’ll be able to run it again with different parameters and see if this time reconstruction is successful.

Understanding differences between RAID Rebuild and RAID reconstruct

Rebuilding or repairing RAID is unsafe and might lead to permanent data loss if the operation is unsuccessful. Using utilities provided by RAID controller manufacturer, you can try rebuilding failed RAID arrays by modifying Disk order. Please remember that the whole procedure is irreversible and can make connected hard drive permanently inaccessible.

Whereas, RAID reconstruction is considered to be safe and can be performed multiple times if the previous operation is unsuccessful.

Reconstruct and Recover RAID hard drive data using recovery tool

Available recovery tool for RAID 5 comes with multiple benefits and capabilities to reconstruct or repair RAID arrays. You’ll be able to recover any type of documents, i.e. Photos, Music, Videos, Emails etc. from a RAID hard drive as well as externally connected media like removable USBs, hard drives, CD DVDs etc.

Stellar Phoenix RAID recovery supports reconstruction on different RAID levels, 0, 5 and 6. It lets you create a virtual RAID level when all the possible reconstruction fails and allows you extracting all the stored files from connected RAID controller disks.

How to reconstruct corrupt RAID arrays and recover data:

  • Download and install this RAID recovery tool on master PC. Stellar Phoenix Lotus Notes Recovery

or Download from cnetStellar Phoenix Windows Data Recovery – Technician

  • Start program from program list or from the desktop.
  • ‘RAID Recovery’ will be listed under ‘Data Recovery’ tab
  • Select RAID levels you’re trying to reconstruct – RAID 0, RAID 5 or RAID 6.
  • All the connected RAID hard drive will be listed under ‘Select Hard Drive to Reconstruct RAID’
  • Use ‘left’ and ‘right’ slider as well as up and down sliders to move hard drive into correct possible order that you could remember.
  • Click on check box stating ‘Don’t know start sector of hard drives. Show list of probable start sectors’ to let software automatically decide the possible start sector.
  • Under ‘Select RAID Parameters’, you can select two or more possible start sector or define yours onto the text box and click on add sector.
  • Further, you’ll need to select stripe/block size, parity order/ rotation and parity repetition/delay under the same ‘select RAID Parameters’ section.
  • Click on ‘Build RAID’ to begin the reconstruction procedure and software will begin applying all the possible combination of RAID parameters to successfully reconstruct RAID arrays for you.
  • You’ll be able to see files stored on RAID hard drive and can recover it to your desired destination drive once the reconstruction procedure is complete.
