I just pooled 4 drives together and put a few video files on them, nothing else. As soon as I pooled them together, the drives have been making noise as though they are being accessed even though there isn't much on them to access and I'm not using anything from them. The GUI shows that 2 files are open and I'm not sure what they are. Is there a way to find out what files are open and possibly making the hard drives make noise? The Windows install is new and I don't believe anything is scanning them. I've set everything in Drivepool (rebalancing, duplication, etc..) to only happen during certain hours at night, but for some reason some files are open and the hard drives are being accessed.
