Imaging RAID 5 array with 2 damaged drives
Even if a RAID 5 array contains errors, Atola TaskForce is able to detect its parameters and image such RAID.
RAID 5 reassembling
1. Connect the drives to the ports of the TaskForce hardware unit. Make sure the ports are in Source mode
2. Click the RAID button in the left-side taskbar
3. Select the drives that make up the RAID array
4. Click Continue

Detecting errors
The TaskForce autodetection module starts running immediately, after you select the RAID devices.
Stage 1: TaskForce reads data on the drives to identify RAID type. If it runs across an error, TaskForce displays error tags next to the respective RAID member.
To see the number of errors encountered on a RAID member, simply hover the cursor over the error tag.
Error tags
Stage 2: TaskForce goes through thousands of possible RAID configurations to identify a suitable one.
Once the configuration is detected, click the Apply button.
Applying the suggested RAID configuration
After you click Apply, TaskForce automatically applies the suggested configuration and checks the file system for partitions.
Despite read errors, Atola TaskForce can mount the partitions for preview by rebuilding the data in the bad sectors using data redundancy inherent to this RAID type.
Imaging RAID 5 array with errors
1. After RAID configuration is successfully applied, click the Go to Image button to proceed with imaging
2. Select your target device/folder and click Continue
3. Click the Start button to launch your imaging session
When the TaskForce system encounters an error, it automatically reconstructs the missing data, using the data in the parity blocks on the remaining RAID members.
Coping with errors
Thus Atola TaskForce can recover the full image. No operator involvement is necessary.

NB: In case 2 drives of the RAID 5 array contain errors in the same sector, TaskForce can still recover the data from those, using the multi-pass imaging system.
Imaging report
Atola TaskForce automatically generates the Imaging completed report with all RAID details and timestamps.
Atola TaskForce managed to successfully reconstruct and image all the data. That is why the number of errors in the Imaging completed report is zero.
