Recurring disk corruption

Hello Experts
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.

Is this a hardware or software RAID 5?  If hardware, you should never run chkdsk on a RAID 5 volume without verifying the volumes integrity first.  The file system may start resorting information that the controller can fix.  Both are usually completely unaware of each other also.

It sounds like you've rebuilt a corrupt partition and all the chkdsk /r is doing is slowing shaving away data the RAID is relying on and probably vice versa.  

If you don't have a good backup, you need to stop everything and copy off all the data and put onto a trusted safe volume.

Your disk are talking to you, but you're not listening. B4 you end up in a recovery position please back up your files and replace the disks

I ran the consistency check utility from Open manage.  I will follow up if that does not resolve the issue.

It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
