I am using RAID array and doing some IO operation and by the way my NAS system getting slower and slower in performance. So i am rebooting the system. After rebooting the system i am not able to see the RAID array. Now how do i recover my data ?? Please help me in recovering the data.
What NAS OS are you using? What file system? What RAID level? Dedicated hardware controller or onboard mobo RAID controller?
Without the above answers, it is difficult to give a specific course of action.
You can replace any bad disks to use the RAID utilities to rebuild the array.
Visit www.runtime.org and check out the applications RAIDReconstructor and GetDataBack. These are free to use to determine if they can recover your data but you must purchase a license in order to enable full functionality and actually recover the data.
