head swap st3500418as

[magnetepazzo]

Hi guys, I have a hdd seagate barracuda 7200.12
sn 6vm386he
st3500418as
p / n p9sl142-621
hp22 firmware, with damaged heads,
I ran a swap from this hdd I had in the laboratory: seagate barracuda 7200.12
s / n 9vmkwa2
st3500418as
p / n 9sl142-302
cc38 firmware
mounting the heads aligned itself regularly and I started the copy, and I managed to copy 250 GB of 500 but then the copy stopped suddenly. By switching off the hard disk and turning it on again, he clicked. Question: do you think the head is broken again because it is not perfectly compatible? or was this also to die?
Thanks so much

likely heads are gone, can we terminal output also ?
