Is it possible to upgrade from 5.2 u4 to DSM6 without the hard drives connected? I have 5 drivers, 4x 2TB for data and 1x 500GB for packages. But one of the 2TB disks has 2 bad sectors. So if I try to upgrade with the drives attached the upgrade fails.
So what I would like to do is to do the upgrade without the 2TB drives connected and then connect them after the upgrade. Are they being recognised as a raid or are they gonna be formatted as soon as I reconnect them to the upgraded system?
