as the hard drive has been dropped it wont be a rom flash problem

the reason for it to be clicking all the time
is that
it has lost its service area alighment
so that why its 0 bytes

and its more likely possible headstack damaged
which your have to replace.

thanks fro replay

i swape head but not worked , i think missed second head
then i swaped head again with original donor

the first time detect (true size) and then not detect again in port terminal

Donor disk for seagate:

1 Same Model
2 Same FW

hi
we need Model and Firmware only to check on Donor Drive for seagate head swap ????
Thanks for any comments.

1. first head write white stiker wy4-t TICB-C
2. second and third head is writed wy4-t TICB-B

Does anyone know the significance of the WY4-T part versus the TIBC-C or sometimes TIBC# part?

Thanks for any insights.

It would seem to be irrelevant on this series drive in my experience.
