NV+ V2 not booting through after reset [24963130]

Perhaps that helps for your further diagnosis:

Via bootmenu I access the technical support and telnet to the NAS and logged in. I see:

-----------------------
/dev # ls | grep sd
sda
sda1
sda2
sda3
sdb
sdb1
sdb2
sdb3
/dev # cat /proc/partitions
major minor #blocks name

31 0 1536 mtdblock0
31 1 128 mtdblock1
31 2 6144 mtdblock2
31 3 16384 mtdblock3
31 4 106496 mtdblock4
8 0 2930266584 sda
8 1 4194304 sda1
8 2 524288 sda2
8 3 2925545912 sda3
8 16 2930266584 sdb
8 17 4194304 sdb1
8 18 524288 sdb2
8 19 2925545912 sdb3
----------------------------------

So the two disks are well recognized with 3 partitions.

And the /var/log/enclosure.log shows:

------
fan!!1!!status=ok::descr=1365RPM
disk!!1!!status=ok::descr=Channel 1: WDC WD30EZRX-00MMMB0, 2794 GB
