I am beginning to think that my Ultra 6 destroys disks for sport. After losing 2 discs simultaneously on a 3-disc array and losing all my data, I rebuilt my array with 6 discs and dual redundancy. Yesterday I got an email that another disc failure was detected (3 months old) and while the NAS seems to still work fine, I cannot access FrontView. It will allow me to login through RAIDar, but it will not load the screen with any data. RAIDar itself seems to work as it shows the NAS and the disc that has been flagged as failed. Anyway, anyone have any ideas. I am scared to turn it off as last time I did that it never turned back on.

Have you inserted the replacement disk yet?
No I haven't. Haven't had time this week. I am going to put the new disk in this weekend and I hope everything goes well. I was able to shut it down successfully.
Question: could having my disk spin-down setting be pretty short (e.g. 10 minutes) be leading to any of these issues I am having with killed disks? I am starting to think that "green" drives are simply incompatible with NASes.
Re: Disk failure and now FrontView will not respond
Well, my initial setup was 3 WD20EADS WD Green drives. After about 3 months, I had two discs fail simultaneously and the third disc failed a drive test. I RMA'ed all of them and added 3 Seagate ST2000DL003 Green drives to bring me to 6 drives with dual redundancy (i.e. 2 disc overhead). After 3ish months one of the ST2000DL003 drives just failed. I am now replacing that with a Seagate ST32000644NS, which is an enterprise level drive. My growing concern with the green drives is that the drive's own power management is fighting with the NASes power management and I am somehow creating failures by cycling the drives on and off too many times. I am going to turn the NAS power management (i.e. spin-down) off for the time being and I am going to replace any more failed drives with enterprise drives. I thought I could save money and power by using the desktop green drives, but it has been more than a headache thus far.
Re: Disk failure and now FrontView will not respond
OK, this gets stranger. I fired the NAS back up so I could do a hot swap and it seems to think the failed drive is fine now. It is rebuilding the RAID using the original failed disk, which is not showing as failed anymore. I am skeptical. I will update after it syncs totally... The good news is I am able to get into frontview again.
Re: Disk failure and now FrontView will not respond
Wanted to update this issue. I had another disk fail this past weekend and as soon as it did, FrontView would not load, despite my setup being X-Raid 2 with dual disk redundancy. I actually am not convinced that X-Raid works that well at all. Anytime I lose a disk, my NAS basically goes through a slow tailspin to completely dead. In the course of 2 days, I got reports of 3 different disk failures, but then when I restarted the NAS, it reported different disk problems. Even more annoying, the RAIDar page will show all 6 disks as green dots, when FrontView reports that one or more are dead.
Why on earth would you design an OS that is not functional/accessible when you have a single disk failure in a multiple redundant system? Could it be that I have a hardware issue?
