During an upgrade cycle of my desktop computer, when I was prompted to reboot, the computer would not reboot. It seems something corrupted the booting portion of the drive.
Yes, I know I'm supposed to back stuff up before performing changes, but in this case I didn't. So... I needed to find a way to recover information off of a raid 10 drive array. I had two sets of two mirrored drives in a striped configuration: Raid 10.
As they were controlled by an Adaptec controllor card, I thought Adaptec might help. They were unable to offer direct assistance, but they did suggest that the sofware offered by Runtime Software would be of use.
I used Runtime Software's tools to examine my drives, and used their paid service to determine the drive configuration. The response back from their paid service indicated that my drives were beyond recovery. Perhaps the settings I used were incorrect for the data capture their software provided to their 'human examiners'. But I would have thought they'd have an idea of what would be correct.
After receiving that bit of bad news, I decided to try data recovery myself. I licensed their tools and gave it a try. Long story short, I was able to recover everything I needed.
The following video shows the steps I used to recover data from a drive array controlled with an Adaptec AH2910SA Drive controller controlling four drives in a Raid 10 configuration.
