I have a client whos server performance had degraded significantly. When I look at the logs I see a bunch of Errors Event ID 11 with the source of Disk. I also have Warnings Event ID 51. For Event ID 11 it says 'The driver detected a controller error on \Device\Harddisk1\DR1' and for Event ID 51 it says 'An error was detected on device \Device\Harddisk1\DR2 during a paging operation. This server is running a RAID 5 using an Intel Matrix Storage Manager to run the RAID but does not have a troubleshooting module. I don't know if it is a bad drive or the controller is having a problem but right now the server is running but for how long. Please help or give me some suggestions.
