I believe there's a CR3032 battery in there, at least, there is on a DNS-323 - however - I am not certain if that battery simply powers a real time clock or also some amount of NVRAM.

Since your unit should be under warranty, I would have it replaced - rather than futz around with it.

I don't think it's the battery, since the date and time does survive a restart or shutdown

The strangest thing is that the settings where saved with the original firmware that came installed (1.03) and the first times I used the box after upgrading it to the latest 1.04 RC

It's more like the settings are not properly written to /dev/mtdblock0 and /dev/mtdblock1, in fact while I was following the fun_plug installation steps:

root@CH3SNAS:~# store-passwd.sh
Copying files to mtd1...
mount: mounting /dev/mtdblock0 on /sys/mtd1 failed: Device or resource busy
Copying files to mtd2...
Done.
root@CH3SNAS:~# store-passwd.sh
Copying files to mtd1...
Copying files to mtd2...
Done.
root@CH3SNAS:~#

I don't know if it could also be a problem with the sda4 and sdb4 data partitions, perhaps the box is messing up the files between the disk partitions and the mtdblock contents?

Right now I'm wiping both hard disks completely (dd if=/dev/zero of=/dev/sdX). Should it be safe to do an rm -f * of the /dev/mtdblock0 and /dev/mtdblock1 contents (rm -f /sys/mtd1/* /sys/mtd2/*)? Are these files recreated when the box is restarted without hard disks plugged in? Should I downgrade to an older firmware in order to "clean" those contents? I would like to make the box forget everything about the hard disks (hd_magic_num, raidtab2web, raidtab,...) in order to do a fresh start, like it's being used just out of the box

Thanks for your help!

please do....
