It's Dead .....
I put the head of the new disk in the old disk (this procedure https://www.youtube.com/watch?v=W_vssaURTrs) ..... result :
* Bad noise, the disk is "clicking" since 20 seconds then stop.
* No way to read anything (nor sector, nor partition table ....)
Then I reverted the operation, new heads in the new disk, old heads in the old disk ... the new disk work .... So I didn't destroyed the heads. Old disk ... can't be read, still clicking .... :-(
Why the new heads where not working on the old disk.
I think I will stop the investigations :-(
RIP the data's.
