Thank You for reply. I have a luck with next variant: In bios I create container with one hdd - raid 0. Next I boot linux (I can see this container as /dev/sda), launch program testdisk - it find all my partiotions and save to disk. After reboot I see all my partitions as /dev/sda1, /dev/sda2 ... etc. I mount it and copy all my data.
Hello I have old 2650 server with perc 3/di raid controller. I have some problems with raid and in result - disappear of the raid 1 container. So, I want to just mount one of the disk in linux from raid 1 and copy all information from it. In BIOS I change RAID to SCSI, but when I mount disk I see nothing on it. Where I was wrong?
