Is there any way to tell which hard drive might be going bad, short of removing one and listening for the other? One of my HD's is making the infamous "click and whee" sound every so often. It clicks then basically starts back up basically. It's not happening too frequently yet, but it did happen twice the other day (and hasn't in about 4 days since) so I'm not super worried yet. I have two hd's in though, and I'm not sure which one is getting ready to start dying. I have a replacement hd but I don't want to put it in and have to deal with formatting, setting up my os, reinstalling, etc. if I don't know which drive needs to be replaced. I couldn't think of any way to tell which one it would be short of taking one out and running with the other...however that could be difficult because I'd not only have to hope to be here to hear the sound, but also have to get a second hd prep'd with an os and software.
