Hi All

I have a server with 2 x 500Gb drives in a RAID configuration. I am not sure what RAID config it is as these are rented servers. The 2 drives mirror each other and I would assume that the server is supplied as much "stock standard" as possible. The server has been operational for 6+ years and has worked fine.

A few months ago, maybe 6 or more, I noticed under Computer Management -> Disk Management that one of the partitions (there are 3) had a warning along the lines of "failed redundancy check" with a small yellow triangle alert icon. I choose the option to resync the drives and this seemed to solve the problem. Now last week this happened again and so I resync'd again. Now today this happened again. I resync and it seems to work fine but obviously this is something that needs further investigation.

Is this a sign the drives are failing? Or would it be the RAID controller? I have contacted their support department but thought I would ask here fwiw as well.

I have a backup server as well and can switch over all functions to it but don't want to go through the hassle if its not warranted to do so i.e. if people in the know of these things don't think its a necessary move - I am not a hardware guy.

Thanks.
