fw:0002bsm1
this hdd was work

conditional repalce head is model hdd
is it true? do you think head fail

[craig6928]

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.

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.
