Hi, i'm using thecus N7700 and the last beta firmware.
7 Drives Wd20Eads and has been running ok until friday night.
Disk 3 dropped and the raid 5 went to degraded. As in my small city I condn't find one of these disks,... I put in the same drive... it took 10 hours to rebuild but the raid was healthy again...

7 Hour late the same disk drop. I was not at home, but also disk 7 drop... So raid went damaged. I restarted the nas and disk 7 was online again and raid appeared again degraded. I have tried to copy some files to my old N5200 but after 5 minutes N7700 went again to damaged because disk 7 drop again. I restart and the raid appears in degraded( but at least is there), i tried again to copy files, but again to degraded.

So what can I do now??? The N7700 is off now and waitting for answers.

I wanna buy two seagate drives. But I can't rebuild raid changing drive 3, because drive 7 is also falling... Can I clone the disk 7 to a seagate to rebuild the raid wich other seagate in disk 3??? Or it can't be possible,... and if it can be done??? What program to clone the two drives???

Thanks in advance for the help.
