Build a 8TB NAS with a NVR DS-7608NI-E2 - Debian

[kapastratos]

Hello there,

I have a DS-7608NI-E2 NVR and at this moment I have nothing to do with it, so I was thinking that with some help, I can build a 8TB NAS (2X4TB hard drives).

Ages ago I did something similar using an NSLU2 and following this tutorial: https://www.cyrius.com/debian/nslu2/

Basically how this worked: short version -> they altered the original firmware to load Debian from an hard drive
and the long version -> https://www.cyrius.com/debian/nslu2/boot/

What I was thinking:

1) alter the original firmware
2) use one usb port for an usb to sata adaptor (I have a 16GB SSD hard drive and I want to install Debian on it)
3) use the 2 internal 2x4GB hard drives in RAID

What I was able to do:

1) extract the cramfs.img from the digicap.dav using hiktools05R1
2) mounting the cramfs.img revealed 6 files

gui_res.tar.lzma
new_10.bin
start.sh
sys_app.tar.lzma
uImage
webs.tar.lzma

Does anyone have any idea that will help me further with this project?

Thank you
