I have an old 2003 server that is used for FTP and also to store non-critical files/folders. It has the OS on mirrored drives and data in a RAID 5 on 5 separate drives. Recently it had a power supply failure and after inserting the new hot swap power supply I got a message that the RAID 5 partition was corrupt. I ran a chkdsk /r and it was fine for a few weeks. Now whenever I copy/move/add a lot of files to folders on this partition, I get the "disk corrupt" message. Running chkdsk /r fixes it but I'm concerned about it getting to a point where it cannot be repaired since it happens about once a month. Are there any programs out there that can repair this partition for good? Any help is appreciated.
