HI AJ2008,
Thanks for the reply.
The ID off this disk " F3 " what i see it always detect the model, FW, ( but if they can not read the SA dont give the size)
I had some disks off 7200.11 tha was head problem and the size was 0MB.
In this case i dont have a donor 5400.6

just 5400.5 but i change heads ( site code match WU, WUXI )
and the heads where not compatible, so i put the heads back to the original disk, and power on ok the first 3 times, them it give the same error and my patiente disk?
So Acelabs, are telling that can be motor problem, but this new disk where working fine ( new disk )
I need a real donor from the same falimy just to see if it´s heads problem or not...
Or i can change the plattes and PCB for the donor disk...
Them i post the progress.
Thanks
Jose
