Example 4 - RAID-0 (Striping) on a HP 454

Configuration:

2 drives with 50000 sectors (24 MB) each.
Originally configured as a RAID-0 (Striping) with a total capacity of 100000 sectors (48.8 MB).
Hardware RAID-0 (Striping) on a Highpoint RocketRAID 454 controller card.
The 2 drives have been copied to image files:
C:\img\raid0\r0_1.IMG
C:\img\raid0\r0_2.IMG

Instructions:

Start RAID Reconstructor.

Select RAID-0 (Striping) as the RAID type. Set # Drives to 2. Enter the names of the image files into the fields labeled Drive1 and Drive2.

Click Open drives.

Verify that the 2 drives show the size of 50,000 sectors and that the total size shows

Number_Of_Drives * Size_Of_Smallest_Drive = 2 * 50,000 = 100,000 sectors

In 4. Analyze, leave the Start sector at 0 because we have a hardware RAID that is most probably starting at sector 0. Also, leave the Block size unchanged. This value will be determined by the analysis we are going to start.

Click Analyze and the analysis wizard will start:

Select Managed Auto (Legacy) and click Next. The wizard will perform a pre-test and determine the block size (128). This will greatly reduce the permutations tested next.

We want to leave the parameters and the number of sectors that we want to probe unchanged. Click Next.

The entry found is around 70% smaller than any other entry. This is good and we get a "RECOMMENDATION: Choose entry #1". Click Finish.

The found parameters got transferred into the corresponding fields in the main screen:

Block size is 128
Drive order is r0_1.img - r0_2.img

Now we are ready to copy the combined array to a virtual image file. Specify a target file name and click Copy.

Immediately after clicking Copy we have a small file c:\img\raid.vim. Mount this image with Captain Nemo or scan it with GetDataBack in order to retrieve the data from it.

Click on Captain Nemo

Voilà, you are ready to copy your files off the lost RAID.
