Back at firmware 1.04 or so there were a bunch of reports about the DNS-323 format process stalling at 94% (or 97% or 98% depending on the reporter...) I was one of those who had this happen. With firmware 1.05, the problem seemed to go away.
I'm now at firmware 1.08 and the problem has returned. I have two new WS 1TB drives where the format will not finish. The format bar hangs at 97% on both RAID 0 and RAID 1 formats. If I abort the format and reboot the DNS-323, the drives appear to be formatted, but I'm wary of trusting them.
I searched the forums and never found a definitive fix for the problem. I tried all the suggestions which I did find: run from a different browser, clear the partitions (none on my new drives...), etc.
Did anyone ever solve this problem?
