Posted by Tim to Data Recovery Tips on April 29th, 2016

I am running a 5 x 3TB RAID5 array on Windows Server 2003. The other day, We had one hard drive failed and since then we have replaced it and the RAID5 has been rebuilt, but our data partition is displaying RAW file system instead of previous NTFS file system, all of my files are inaccessible. It continually asks me to format the drive, of course, I am not prepared to do at this point. How to recover lost data from RAW RAID 5 array, please help?
