DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hi all,

first of all, sorry for my poor english !

I decide to flash my stock firmware of my dns 323 rev B1 (1.09) to alt f rc4.

but ...... my hdd are in raid1 (i think in ext2).

When i flash the firmware, did i loss all my data ? because i have 2 TO in this nas, and i can't backup this 2 to (i haven't 2 TO free anywhere).

I've read in this forum no data loss for jbod, but any response for raid 1.

thanks
