Using Reclaime Free RAID Recovery with iRecover

Reclaime Free RAID Recovery (www.freeraidrecovery.com) is a RAID recovery utility that detects parameters for broken RAIDs. It is free to use but additional steps are required when using it to recover data from a broken RAID.

You can create an image of the 'recovered' RAID using Reclaime Free RAID Recovery, or you can use additonal data recovery software to recover data from the broken array directly. If you have an iRecover Pro license you can use iRecover to process the parameters as detected by Reclaime Free RAID Recovery, by simply following the instructions provided for Zero Assumption Recovery (ZAR) by the Reclaime software.

Note that the use of Reclaime Free RAID Recovery is not a requirement for iRecover to rebuild a broken array, as iRecover is capable of detecting the array parameters automatically! It may however speed the recovery up quite a bit because you can skip iRecover's RAID detection phase.

These example instructions are provided by Reclaime for recovering a WD Sharespace RAID 5.

  • Launch iRecover.
  • Click "Data Recovery for Windows and Linux". We will use the data we got from Reclaime to define the RAID.
  • Right click anywhere in the disk list, select "Define RAID manually".
  • From the "Available drives" list, select "Disk 2 - WDC WD10 EARS-00MVWB0", then click "Add".
  • From the "Available drives" list, select "Disk 1 - WDC WD10 EARS-00MVWB0", then click "Add".
  • From the "Available drives" list, select "Disk 3 - WDC WD10 EARS-00MVWB0", then click "Add".
  • Next to the "Array members" table, click "Add parity".
  • From the "Array members" table, select the last entry (ID 0500).  Click "Move up" 3 times. Verify that the parity drive (ID 0500) is at row 1 (the top row is number 1).
  • On the right side under "Array configuration", set "RAID type" to "RAID5 (MS/LDM)".
  • Below that, set "Stripe size" to "128 sectors".
  • Below that, set "Parity start/rotation" to 3/3.
  • In the "Array members" table, enter "48,1953523055" as "Start, Size" in all rows.
  • Set "Parity delay, stripes" to 1.
  • Set "Stripes in first delayed block" to 1.
  • Click "OK". A warning message may appear stating that "Starting sectors and sizes are incorrect". Click "OK" to dismiss the message box, then click "OK" on the manual RAID setup form again to close the form.
  • In the device list, "Virtual RAID #0" is the newly created RAID. Double click it to start recovery.
