Disk Replacement : Nas unreachable...

Hello
Since few weeks i try to replace a 2 To disk on my Network space vs2 classic : the old one is die.. i found your site and was very impatient to try !
I try first with the fvdw-sl-console and firmware 15.1 and all was working well in the script but at the end of the process, when i reboot the box, i cannot browse or ping it.....
So i read some posts and try version 11.0 with manual installation. After experienced the disk block size issue on a USB/SATA enclosure (block size was 4096) i connect directly on a sata port and performed installation, but with the same results as above.
I have flashed the u-boot to have GPT partition support and retry install with console...same result
So now i don't know what is wrong on my disk. Below is the Fdisk result command
I think about the MBR block : perhaps i have to wrote one on the disk ?
Disk /dev/sda: 2000.3 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 9 72 514080 83 Linux
/dev/sda2 73 136 514080 83 Linux
/dev/sda3 137 200 514080 82 Linux swap
/dev/sda4 201 243201 1951905532+ 5 Extended
/dev/sda5 209 312 835380 83 Linux
/dev/sda6 321 328 64260 83 Linux
/dev/sda7 337 400 514080 83 Linux
/dev/sda8 409 243201 1950234772+ 83 Linux
Thanks to give me some ways to troubleshoot my Nas.
