Hope this makes sense...
2 days ago StableBit Scanner and WHS 2011 reported that a drive was failing....and a brand new 6TB WD Red drive of all things!
So I shutdown the server, physically removed the drive and backed up the data to another 6TB drive. I mostly backed up the Server Folders that I don't have duplication turned on for - as the duplicated server folders should be ok (dupe copies on the other drives) - correct?
So I was all set to add the NEW 6TB drive into the pool and then follow the instructions in this posting: http://wiki.covecube.com/StableBit_DrivePool_Q4142489
