Hi,
In the worst case, read this link, http://forums.dlink.com/index.php?topic=41395.0 , it's in the 323 fac. The factory reset even without removing the disks might be an alternative and is supposed to have no effect on the data or the raid configuration, but you will have to redo your users and any other settings you made. Or you could go with fordem's recommendation and try removing the drives first. In either case, you should be able to recover your data unless somehow both drives got toasted somehow, which I doubt. It just seems to me you have to try the factory reset with or without the drives in place. If you decide to try the reset, you insert a paperclip into the reset hole on the back and hold it in for 10-15 seconds with the unit power on. Good luck
