I've got a 1.5TB raid5 array with a Areca 1120 controller running in win 2k3 server. This past weekend has been quite frustrating for me with random fits of corrupt data. Then a reboot to run chkdsk which seems to fix it and I regain access to my files for a brief time until it repeats. I've been reading some posts and I keep seeing reference to faulty hardware. I assume one of my drives has some bad sectors or soon to be bad sectors on it. How do I find out which one of my drives in the raid array is bad/going nuts? I'm pretty new to this raid stuff and I do keep back up DVDs of my important data but I would really like to get this file corruption issue resolved so I do not have to reboot and run checkdisk every time I work with files on the system. I need to spend some time on the box to see if the controller has any features to allow for individual disk checks but if anyone has any other tips/tricks/advice that you don't mind passing along that'd be great.
