RAID Recovery: The Data Knight Kroll Ontrack To The Rescue!

Tom’s Hardware goes into Ontrack and reports on the world of data recover. Lots of good information on data recovery and costs. Recovering data from “RAID systems can reach the five-digit zone rather quickly”, so it’s definitely worth investing in a good backup mechanism before disaster occurs.

Hard drive failure is especially disastrous for smaller companies working with a single server and a single disk, if they do not have a complete and working data backup at hand. The whole situation is even more complicated if the broken hard drive is a member of a RAID array. Neither hard drive failure in RAID 1 nor RAID 5 will result in data loss, since this scenario has been taken care of by the choice of these RAID levels in advance. But the risk of human error increases: self-made data loss occurs if you accidentally substitute the wrong drive in a degraded RAID 5 array (one with a failed hard drive).
