I assume a drive in the console is showing as unhealthy or failing right now? Have you tried
running chkdsk on all your drives ? Have you reviewed the various potential causes of file conflicts in
this FAQ ?
Unfortunately, the console doesn't offer a way to associate a drive in the Storage tab with a mount point in C:\FS. Probably the easiest way to figure out which drive it is would be to shut your server down and disconnect a drive, then restart it. This sounds drastic, but it's really pretty harmless. The drive you've disconnected will show as "missing". If it's not the right one, reconnect it and try another.
In the longer term, you may want to look into the add-in Disk Management by Sam Wood. It will help you to identify the drives you have installed in your server. I wouldn't install it right now, though; you should really solve your current issue first.
I'm not on the WHS team, I just post a lot. :)
