Hello,
I am using Windows 7 64-bit
Here is my problem. I have a 2 TB hard drive at 5400 rpm that contains a C partition (system, programs...), an E partition that contains data, and an F partition that contains the files I use for video editing (video captures, images of the videos I have finished...). I have a new 500 GB hard drive that runs at 7200 rpm. I want to use this disk as partition C. I have made a backup of the 3 partitions (C, E, and F) with the software I use for backups: NORTON GHOST 15.0. I restored the C partition onto the new 500 GB drive and started Windows, no problem. On the 2 TB hard drive, I formatted the old C partition (I performed this operation on my wife's computer with a dock for 3.5 or 2.5-inch hard drives). When I connect this drive to my computer and restart the system, Windows begins to boot then I get a blue screen for 1 second and the system reboots and this goes on in a loop. By disconnecting the 2 TB drive, Windows starts without any problem. If I connect the 2 TB drive after Windows has started, this drive is not recognized. Going to 'Computer', 'Manage', and 'Disk Management', there is a red cross in front of this disk and a message indicating this: 'The disk is offline because it has a signature collision with another disk that is online.'
How can I remove or modify this signature knowing that the old C partition has been formatted? Only partitions E and F have been kept. If I need to delete all the data on the disk, that is not a problem as I have taken, as a precaution, 2 backups of partitions E and F.
Thank you in advance for your help.

Hi,
found this on a forum, but never tested:
go to disk management, right click on the problematic hard drive and click on "Online", what does that do? Sometimes it works just that simply.
Otherwise, there is a solution to change the disk signature:
in blue the commands to type
In a command prompt (-> run type CMD and enter), launch diskpart
List the hard drives with the command list disk
select the disk that has the issue (the one offline) with the command select disk XX where XX is the disk number given by the list command
List its ID with the command uniqueid disk
change its ID with the command uniqueid disk id=11ABC1111 where 11ABC1111 is an ID that you choose yourself.
I think the command uniqueid disk id=MYDISK should also work

All problems have a solution, if there is no solution... well there isn't one, since that's what we're told!
