from a 2.5 hitachi i attached this sound noise
any advise will be appreciate,
i suspect motor jammed-> i will try to brutal force the motor into the clean room,
but i wanted to post here for a confirmation from a somebody more expert..

Mi sembra che usi questo metodo un po' troppo... deve essere un'abitudine .... guarda che spostare l'insieme dei piatti su uno chassis funzionante quando serve serve ! E' piu' facile a dirsi che a farsi, comunque .
P.S. sei proprio sicuro che il motore sia bloccato?

I noticed that you use this method too often... Must be an habit .... please notice that sometimes,when needed, you have to move platter pack to a good chassis!
Easier to say than do, anyway
P.S. are you really sure the motor is seized ?

well i am not sure - tomorrow i will enter cleanroom and check it out.

last drive, 7200.11, needed a special platter swap ( i have SD'tools,and do not allow me the work )
this drive instead do not need a special platter swap, so i am wating the donor, until than ,i can only be patient and wait.

one thing that i'm asking myself: once i will loose the alignment of the platters, another DR company can still recover the data?

Si ma se prima costava "x" in quel caso costa una fucilata ! (ammesso e non concesso che si riesca e in tempi ragionevoli)

Yes but if originally the cost was "x" , then it will cost an arm and a leg ! (assuming it can be done and in a reasonable amount of time)

could you be nice and explain the reason/reasons it will increase the cost of data recovery?

Semplice : quanti sanno come risolverlo e cosa serve ? Sono cose che si pagano care - non posso darti altri dettagli.
Simple : how many people know how to do it and what is needed ? These things are damn expensive - can't give more details.
