The procedure is complicated as the OS of the 2Big2 is not designed to be installed manually. The box was sold with OS installed.

A simple dump of an existing installed disk won't work, because the size of the disk is important, and there are some flags to tell the OS it's a new install, which are removed after first setup.

The installation procedure is here: https://web.archive.org/web/20180817011242/http://lacie.nas-central.org/wiki/Installing_firmware_on_fresh_disks_(2Big_2)
and the needed partition dumps can be found here: https://www.mediafire.com/folder/me9cyqnlp00cm/Lacie#8lpolhj1341v4

Hm. It's not clear to me why that file was missing. Anyway, the original is lost in cyberspace. I created&uploaded a new one, based on the description in the Wiki. Its basically the mbr + a flag (LaCieFirstBootLaCie) in sector 4. It's not clear to me why the original file was bigger. Maybe it contained some noise, generated because the disk from which it's cloned had a history. This file is generated from scratch.

this is the file missed

mbr+label.gz 269 2011-Apr-30 18:21

this is the first step that i make it

Init the disk by running: gzip -dc //mbr+label.gz | dd of=/dev/sdd

see this link to understand why i say is missed ... But my linux experience is very very low and i m like a Monkey if i say something wrong forgive me FOUNDED SORRY

the missing file dimension can depend from the HD size (i had 2tb hard disk) ?

Yes, as I wrote, I uploaded a new example.

Yes. But I'm not gonna do it. The script would basically contain the commands listed in the Wiki, but wouldn't be able to intelligently react on errors.
Further it's impossible for a script to decide which disk should be prepared. (You can look at /proc/partitions, as you know which disks are available).
