For some reason it's still running, but when I want to Ghost the OS partition it gives me an error: "Read sector failure, result = 1, drive = 0, sectors 16864623 to 16864687". Also I'm getting a new hdd today. The setup is as follows: 2 drives in RAID, 2 partitions, the OS partition in stripe, the data partition in mirror. When I remove the old failing drive and plug in the new drive, how should I proceed to setup the RAID again? EDIT: managed to copy the partition using Acronis TrueImage. Phew!
