Physical RAID Imaging

I've only ever had one RAID issue to deal with so am a complete novice - we had a sister company with a failed server that our internal IT dept said couldn't be recovered.

\We deduced from the controller that RAID was in play, then used the free element of Runtime Software's suite and were able to establish what type of RAID it was, then purchased the necesary license to recover data (didn't have to look at slack space)

Realise this a simple point-and-shoot option that may not address your issue )

Cheers
