the disk make clicking noise. i changed the heads, it still continues to clicking but its recognize the disk.
after i put the heads back and its the same problem its clicking and recognize but i cannot take the data.
and my donor works well before changing the heads.

my question is if the disk can make problem to the heads?

Either something went wrong during the head swap, or the patient has some platter damage killing the heads.

Hello, A better description of the case could give us a better look.
Patient and donor models, the history behind the problem etc etc.

hello,
thank you for your answer. the model is WD400BD and the doner is the same and the same dcm. i change the head with the special plastic tools and i used the imager tool.
when i change the head and i don't make any physical damages. when i put the head back to the doner, it can not read any data and the head makes clicking noise.

I would say alignment problem...at least.
